Call-Up Report — 5/15: Waldschmidt Arrives, Mack's Breakthrough Window Narrows

Cooper Ingle is the sharpest STASH NOW target: CLE's catching crater (.374 OPS incumbent) paired with a 24-year-old AAA composite-74 prospect with 2026 ETA creates a real opportunity window. Ryan Waldschmidt becomes the week's most STICK-eligible call-up after ARI DFA'd their #1 center fielder and handed him the starter role (6/6 starts, 9th-order spot).

Call-Up Report — 5/15: Waldschmidt Arrives, Mack's Breakthrough Window Narrows

Cooper Ingle is the sharpest STASH NOW target: CLE's catching crater (.374 OPS incumbent) paired with a 24-year-old AAA composite-74 prospect with 2026 ETA creates a real opportunity window. Ryan Waldschmidt becomes the week's most STICK-eligible call-up after ARI DFA'd their #1 center fielder and handed him the starter role (6/6 starts, 9th-order spot).

👀 Call-Up Watch — Six To Watch

Full board: Call-Up Watch.

Cooper Ingle · C · CLE · Confidence: Medium

Top-100 AAA catcher whose path just got more complicated — but the DH/flexibility angle keeps the window open.

The case for promotion Cooper Ingle is the Guardians' #84-ranked MLB Pipeline prospect, age-appropriate at 24.2, with a composite 74 (perf 94.93, traj 80.46, age-score 85.57). The trajectory score (80.46) signals continued improvement, not a plateau, and the perf score is elite. Not yet on the 40-man, which is the meaningful short-term obstacle.

MLB opening The opening just changed shape. On 2026-05-09, CLE acquired Gold Glove catcher Patrick Bailey from SF for LHP Matt Wilkinson and the No. 29 pick, and simultaneously optioned former primary starter Bo Naylor to AAA Columbus. The new MLB room is Bailey + Austin Hedges — a defense-first duo that the league rates among the best behind the plate. This is not a "failed incumbent" opening; it's a defensive-overhaul opening. Ingle's path is now less about displacing a crater and more about forcing his way into DH at-bats if Bailey/Hedges' combined offense stays light.

Fantasy verdict STASH — top-100 prospect, elite composite, but the trade narrowed the short-term avenue. The realistic ETA shifted from "6–8 weeks if incumbents crater" to "summer call-up if his bat plays up and CLE wants offense at DH." Worth holding in deep and keeper formats; not a standard-mixed grab yet.


Edwin Arroyo · SS · CIN · Confidence: Medium

YOUNG-FOR-LEVEL SS riding a 156 wRC+ Triple-A breakout, blocked by a healthy star.

The case for promotion Edwin Arroyo is 22.7 (YOUNG-FOR-LEVEL at AAA Louisville), 40-man rostered, composite 72 (perf 76.81, traj 100.0, age-score 96.37). The 100.0 trajectory is the headline — a swing adjustment this spring (higher hands, more weight transfer) has produced .342/.408/.590 with 8 HR through 39 AAA games. He's added 2B (12 G) and 3B (2 G) reps, which matters for any path that doesn't displace De La Cruz.

MLB opening Elly De La Cruz is hitting (.884 OPS, 10 HR / 195 PA) and isn't moving off SS. The real opening is positional flexibility: CIN's bottom-third (Stephenson, McLain, Hayes) has been a black hole, and Arroyo's 2B/3B reps suggest the org is preparing him for an infield-anywhere role rather than a pure SS slot.

Fantasy verdict STASH — elite trajectory + 40-man + positional flex against a struggling lineup is the bull case. Realistic ETA: 4–8 weeks if CIN decides offense beats defense at 2B/3B. The lack of an SS opening keeps this from being a standard-mixed grab.


Jimmy Crooks · C · STL · Confidence: High

Trajectory-100 AAA catcher with the softest incumbent room in baseball ahead of him.

The case for promotion Jimmy Crooks is at AAA Memphis, age-appropriate at 24.8, already 40-man, composite 74 (perf 82.91, traj 100.0, age-score 76.49). The perfect 100.0 trajectory matches the elite-acceleration archetype. STL added him to the 40-man for a reason.

MLB opening The clearest in the league. Yohel Pozo has .500 OPS / 0 HR in 26 PA. Pedro Pagés is .596 OPS / 3 HR in 100 PA. Iván Herrera's health has been a persistent question. STL's "overabundance of catchers" pre-season is now a "no one is hitting" reality, and Crooks is the only catcher in the org with an actual offensive profile.

Fantasy verdict STASH with the highest conviction on this list. The combination of trajectory 100, 40-man, no competing prospect depth, and three failing incumbents is the cleanest setup on the board. Realistic ETA: 4–6 weeks. Catcher is the weakest fantasy position; this is a free roster slot in any mixed league with two C spots.


Jonah Tong · SP · NYM · Confidence: Medium

Young SP with 40-man seat — and the IL event that opens his window just happened.

The case for promotion Jonah Tong is YOUNG-FOR-LEVEL at 22.9, 40-man rostered, composite 69 (perf 69.08, traj 23.16, age-score 95.69). The trajectory score (23.16) is the real flag — it suggests volatility, not the smooth acceleration of an Arroyo or Crooks. He's getting the AAA Syracuse innings to test whether the perf score is stable.

MLB opening Kodai Senga — 20.0 IP, 9.00 ERA, 1.95 WHIP — was placed on the 15-day IL on 2026-05-13. This was the predicted IL event from previous editions of this board; it's now real. The Mets' rotation depth has been audited (six-starter plans in spring) but Senga's spot is the open one, and Tobias Myers (3.51 ERA over 25.2 IP as the long-relief swingman) is the more likely first-call replacement.

Fantasy verdict WATCH — Senga's IL is the event we were waiting for, but Myers is ahead of Tong in the depth call order. Tong's path opens if Senga's IL extends past 15 days OR if Myers gets stretched out as a starter and leaves a long-relief hole. The 23.16 trajectory caps the upside even on call-up. Hold off in standard mixed; deep-league lottery only.


Emmanuel Rodriguez · OF · MIN · Confidence: Medium-High

Composite-66 OF (40-man) facing a .353-OPS hole that's begging to be filled.

The case for promotion Emmanuel Rodriguez is age-appropriate at 23.2, 40-man rostered, composite 66 (perf 79.87, traj 80.96, age-score 94.21). Solid mid-tier prospect with trajectory support. AAA St. Paul is the launchpad. Pipeline #69.

MLB opening James Outman is one of the league's worst regular performers — .353 OPS overall, .121 average, out of minor league options, openly discussed in beat coverage as a DFA candidate. Trevor Larnach is pedestrian (.779 OPS, 1 HR in 118 PA). The depth alternative is Alan Roden, who Twins beat writers cite as the more likely first call. Top prospect Walker Jenkins is also climbing.

Fantasy verdict STASH — 40-man, age-appropriate, in front of a near-certain DFA. The wrinkle: Roden is the on-deck name in current Twins coverage, not Rodriguez. If MIN goes with Rodriguez (the higher-upside play), this is a 4–6 week window. If they go Roden first, Rodriguez's ETA pushes to midsummer. Roster in deep mixed; monitor Outman's roster status this week.


Cole Carrigg · OF · COL · Confidence: Low

Composite-65 OF (no 40-man) facing a real OF crater but with no organizational signal.

The case for promotion Cole Carrigg is 24.0, AAA Albuquerque, composite 65 (perf 69.6, traj 60.68, age-score 87.87). Trajectory is soft. No 40-man — the most meaningful short-term blocker, because COL would have to clear a roster spot to call him up.

MLB opening Brenton Doyle (.513 OPS) and Jordan Beck (.532 OPS) are both sub-.550 disasters. The hole is real; COL's outfield is a wasteland.

Fantasy verdict WATCH — opening is real, prospect profile is marginal, no 40-man seat means COL would need to actively decide on him over other org options. Realistic ETA: indefinite. Dynasty-league hold only.


Kade Anderson · SP · SEA · Confidence: Low (long-term)

Composite-75 arm at AA Arkansas — 2027 ETA, not a 2026 stash.

The case for promotion Kade Anderson is age-appropriate at 21.9, composite 75 (perf 90.9, traj 50.0). He is at Double-A Arkansas, not AAA — he has not yet pitched above AA. Elite perf score, but the 50.0 trajectory is mid-tier (small sample at level). ETA 2027 is realistic.

MLB opening SEA's rotation hole is shallow. Alex Hoppe (6.75 ERA, 6 IP) is in a small-sample bullpen role. Logan Gilbert anchors at 3.78. Bryce Miller and the AAA depth are ahead of Anderson in any internal call-up order.

Fantasy verdict WATCH for 2027. Composite 75 is genuine, but the AA level and lack of multi-year arc means he's a dynasty-league asset, not a 2026 call-up play. Drop in redraft.

Ryan Waldschmidt · ARI · CF

Recalled 2026-05-08 · 7 days ago · 7 G / 6 GS

Usage: 🟢4 05-08 · 🟢9 05-09 · 🟢9 05-10 · 🟢9 05-11 · 🟢9 05-12 · 🟢9 05-13 · 🔴B 05-15 86% start rate, batting 9th in 5 of 6 starts. Single bench day is noise.

Context: ARI DFA'd Alek Thomas on 05-08 and handed Waldschmidt the CF #1 role. No IL'd incumbent — this is a permanent reckoning, not an IL fill. Org's #1 prospect designation (per @BNightengale) backs the long runway.

Verdict: STICK — clearest opportunity on this list. DFA replaced him into a starter role; only catastrophic performance reverses the call. Rosterable in all mixed leagues.


Gage Workman · DET · 3B

Recalled 2026-05-10 · 5 days ago · 5 G / 4 GS

Usage: 🟢9 05-10 · 🟢7 05-12 · 🟢9 05-13 · 🟢5 05-14 · 🔴B 05-15 80% start rate, batting 9th in 2 of 4 starts. One bench day too early to weight.

Context: Filling in for Gleyber Torres (depth #1, IL, no return ETA). Composite 56.95 (perf 64.54, age 37.99). 2025 AAA: .229 / .806 OPS, 15 HR / 10 SB in 346 PA. 2024 AA: .280 / .842, 18 HR / 30 SB — clear breakout that stalled at the higher level. Versatility (called up as 3B, listed as 2B #4 on depth chart) is a feature.

Verdict: STICK — named IL'd incumbent + 80% start rate + power-speed AAA profile = 4–6 week minimum window. The clearest "real opportunity" call on this list alongside Waldschmidt.


Petey Halpin · CLE · CF

Recalled 2026-05-01 · 14 days ago · 14 G / 7 GS

Usage: 50% start rate over the full 14-day window; bench rate increasing in second week (3 bench days in last 7 vs. 4 in first 7). Context: No IL'd incumbent. CF #4 depth chart. Audition period has been long enough for CLE to settle into a platoon/bench role, and the rolling start rate is trending down, not up.

Verdict: TEMPORARY — usage trend is the signal here. Two weeks of 50% with declining trajectory suggests CLE has seen what they need. Drop in standard mixed; monitor in deep.


Zach Cole · HOU · LF

Recalled 2026-05-04 · 11 days ago · 11 G / 7 GS

Usage: 64% start rate, batting 8th in 2 of 7 starts. Recent benching (05-15) follows an HBP on 05-13. Context: Per @brianmctaggart (05-14): "Zach Cole hit by a pitch on his left foot, which is not the foot that was struck by a pitch in the Minors and put him on the IL." Original call-up framing was matchup-specific ("recall to face Yamamoto, Ohtani"). Chronic lower-body vulnerability.

Verdict: TEMPORARY — recall context (matchup-specific) + injury history + recent precautionary benching = short-term utility call. <10-day window probable. Avoid in standard mixed.


Joe Mack · MIA · C

Recalled 2026-05-04 · 11 days ago · 11 G / 6 GS

Usage: 55% start rate, batting 8th in 3 of 6 starts. Hot opening (7 G in first 9), cooling recently (2 consecutive bench days 05-14 and 05-15). Context: No IL'd incumbent. C #2 depth chart. MLB Pipeline #44. Per @CraigMish: "Marlins Catcher Joe Mack 'They called me up for a reason.'" — Mack's own quote on arrival.

Verdict: TEMPORARY — 55% start rate with cooling trajectory suggests MIA is auditioning, not committing. Two-catcher mixed leagues only.


Jesus Rodriguez · SF · C

Recalled 2026-05-04 · 11 days ago · 11 G / 5 GS

Usage: 45% start rate, batting 9th in all 4 starts with lineup data. Three bench days in 11 games. Context: No IL'd incumbent. Depth chart lists C #1 with role=starter, but actual usage is platoon. SF traded their starter Bailey to CLE on 05-09, which marginally opens the room — but Rodriguez has not absorbed those starts. MLB Pipeline #44.

Verdict: WATCH — the Bailey trade should have opened starts for Rodriguez; it hasn't yet. Either SF is committing to a platoon or another catcher is coming. Revisit in 7 days; if start rate >60%, upgrade to TEMPORARY.


Bryce Eldridge · SF · DH/1B

Recalled 2026-05-04 · 11 days ago · 11 G / 6 GS

Usage: 55% start rate, batting 5th in 3 of 6 starts. Three bench days in 11 games. Context: No IL'd incumbent. Depth chart: 1B #2, role=backup. Per @susanslusser (05-12), manager Tony Vitello "made clear Eldridge mostly will come off the bench with Devers the primary 1B and Schmitt the team's most productive hitter all year." MLB Pipeline #18.

Verdict: TEMPORARY — manager has publicly cemented bench-heavy role. Pipeline #18 is elite, but lineup construction caps at-bats. Super-deep mixed only.


Spencer Jones · NYY · RF

Recalled 2026-05-08 · 7 days ago · 7 G / 3 GS

Usage: 43% start rate, batting 6th in 1 of 3 starts. Two bench days in 7 games. Context: No IL'd incumbent. Depth chart: RF #2, role=backup. Per @BryanHoch (05-08): "'A large man who hits the ball very far,' Spencer Jones is en route to Milwaukee... expected to make his big league debut after being called up on Friday." Hype-vs-usage gap is the story.

Verdict: WATCH — 43% start rate over 7 days is too thin to read. Revisit after 10 G; if start rate clears 60%, upgrade. Home-run-only formats can roster now; standard mixed should wait.

Scoring glossary: All prospect scores are on a 0–100 scale. Composite = weighted blend of the three sub-scores below.

  • perf = production at current level (stats vs. league/level baseline)
  • traj = improvement curve (year-over-year acceleration, age-21 80+ = elite)
  • age-score = age relative to level (younger = higher) A composite of 70+ signals a top-100-caliber profile; 60–70 is mid-tier; below 60 is org depth. MLB Pipeline ranks are external (mlb.com) and noted separately when used.

Verdict legend (consolidated to 4 categories):

  • STICK — real long-term role; rosterable now in standard mixed
  • TEMPORARY — 2–6 week window, often IL-fill; matchup play
  • STASH — minor leaguer with credible 2026 path; hold in deep or keeper
  • WATCH — insufficient signal yet; revisit after 7–10 more games
