Deep Dives

Dustin May (SP, STL, 18% owned)

  • L14 line: 2G, 11.1 IP, 7K/3BB, 2.43 ERA across two starts as STL's SP#1.
  • Underlying: Season ERA sits at 5.84 but FIP is 4.01 — a 1.83-run gap that screams positive regression. The recent 2.43 ERA is the real version of May, not the bloated overall mark.
  • Role / playing time: Listed as SP#1 on the Cardinals depth chart. No IL flags, full rotation lock.
  • Recent news: No recent tweets in the buzz feed, but the role and trend tell the story.
  • Verdict: Strong add in 10+ team formats. Buy signal at 70.16 is the highest pitcher score on the board. The peripherals match the recent results — this is a classic buy-low window before the ERA catches up.

Matthew Boyd (SP, CHC, 73% owned)

  • L14 line: 2G, 8.2 IP, 9K/2BB, 7.68 ERA. The ERA is ugly, the strikeouts are not.
  • Underlying: Season ERA 5.79 vs FIP 1.63 — a 4.16-run chasm. That's one of the loudest regression flags you'll ever see. 9K/2BB in 8.2 innings is ace-tier.
  • Role / playing time: Cubs SP#1, currently on the IL. Stash-and-wait scenario.
  • Recent news: No specific tweet, but the IL designation is the only thing keeping ownership from spiking past 80%.
  • Verdict: Strong IL stash if you have the slot. Buy signal 69.85. He's just over the 70% cutoff but worth flagging because the FIP is absurd.

Lucas Erceg (RP, KC, 49% owned)

  • L14 line: 7G, 7 IP, 8K/7BB, 1.29 ERA, 4 saves, 1 BS.
  • Underlying: No advanced rationale flagged, but 4 saves in 7 outings + the CL#1 tag is what matters for closer chasers. The 7 walks are a yellow flag for ratios.
  • Role / playing time: Listed as CL#1 (closer) on the Royals depth chart — the job is his.
  • Recent news: None in the feed.
  • Verdict: Strong add in any league chasing saves. The walk rate is scary but the role is locked, and at 49% owned he's the best available pure-saves grab on the wire.

Max Meyer (SP, MIA, 27% owned)

  • L14 line: 3G, 17.1 IP, 20K/4BB, 1.05 ERA. That's an 11.1 K/9 over the sample.
  • Underlying: Buy/sell flagged as Hold (44.44) on small-sample caveat, but the K-rate is doing the talking. 5:1 K/BB and a sub-1 ERA across three starts is real performance, not BABIP smoke.
  • Role / playing time: SP#4 on Miami's chart — slot is secure, no IL flag.
  • Recent news: None cited.
  • Verdict: Strong add in 12+ team leagues. Even if the ERA balloons, the 20-K pace is the kind of thing you don't leave on waivers. The Hold signal is small-sample noise.

Sean Burke (SP/RP, CWS, 16% owned)

  • L14 line: 3G, 19.1 IP, 15K/2BB, 0.94 ERA. A 7.5 K/BB ratio in three starts.
  • Underlying: Hold signal (40.85) flags small sample, but a 0.94 ERA with only 2 walks is built on real command, not luck.
  • Role / playing time: SP#4 on the White Sox — innings are secure, even if the team context is rough.
  • Recent news: None cited.
  • Verdict: Streamer with upside in 12+ team formats. The White Sox offense and bullpen will limit win equity, but the ratios are too clean to ignore.

Aaron Civale (SP/RP, ATH, 14% owned)

  • L14 line: 2G, 10.1 IP, 8K/2BB, 2.67 ERA.
  • Underlying: Hold (41.06) due to small sample. The 4:1 K/BB and sub-3 ERA suggest the version we saw in Tampa years past is back.
  • Role / playing time: SP#2 for the Athletics — full rotation gig.
  • Recent news: None cited.
  • Verdict: Streamer-plus. At 14% owned in a deep league he's a quality No. 5 SP gamble. Matchup-dependent for shallower formats.

Nathaniel Lowe (1B, CIN, 7% owned)

  • L14 line: 9G, 11-36 (.305), 5 HR, 10 RBI, 8 R, 3BB/6K.
  • Underlying: Buy signal (60.48) flagged as small-sample, but 5 HR in 9 games with only 6 K's is a power-and-contact combo you bid on.
  • Role / playing time: Listed as 1B#3, which is the one concern — playing time may be split. But the bat is forcing the issue.
  • Recent news: None cited.
  • Verdict: Strong add in 12+ team leagues. 7% ownership for a guy posting a 5-HR L14 in Great American Ball Park is a market inefficiency.

Nick Gonzales (2B/3B/SS, PIT, 11% owned)

  • L14 line: 12G, 21-53 (.396), 6 RBI, 7 R, 1 SB, 4BB/9K.
  • Underlying: Hold (52.68) on small-sample. The contact is loud (.396 AVG, 9 K's in 12 games), even without the power.
  • Role / playing time: 3B#1 with 2B and SS eligibility — that triple-position flexibility is the real prize.
  • Recent news: None cited.
  • Verdict: Strong add for MI/UT slots. At 11% owned with 3-position eligibility and a .396 hot streak, he's the best deep-league middle-infield grab on the page.

Quick Hits

  • Bryan Baker (52% owned, TB) — 4 saves L14, listed CL#1, no advanced flag yet. Saves chasers add now.
  • Jack Perkins (24% owned, ATH) — 3 saves, 7K/0BB in 6 IP. RP#3 on chart so role murky, but the line is loud.
  • Chase DeLauter (64% owned, CLE) — .347 with a .212 BABIP, signal flags AVG should rebound. Worth a final-week grab.
  • Brice Matthews (1% owned, HOU) — .292 with 2 HR/2 SB at CF#1. Speed-power deep stash.
  • Janson Junk (5% owned, MIA) — 11 IP, 0.00 ERA as MIA's SP#5. Streamer only.

Skip / Already Gone

Over 70% owned and not the focus today: Kazuma Okamoto (74%), Matthew Boyd (73% — covered above as the rare exception because the FIP gap is historic), Kris Bubic (76%), Emerson Hancock (77%). Also fading hard despite the buzz: Justin Wrobleski (61%, Strong Sell 24.25, velo down 2.2 mph), Clay Holmes (64%, Strong Sell 22.37, FIP 4.33), Nick Martinez (34%, Strong Sell 24.38), and Kyle Finnegan (11%, Strong Sell 22.65 — 0.00 ERA vs 4.47 FIP). Don't chase those ERAs.
