TL;DRSkim

The five fastest-moving roster calls of the morning, in priority order:

• HOLD — Marcus Semien (NYM, 2B, 38% owned): out 4-6 weeks with a Grade 3 hip flexor strain — IL him, and Ronny Mauricio (0% owned) is the deep-league fill-in for everyday 2B reps.
• WATCH — Jazz Chisholm Jr. (NYY, 2B): in concussion protocol after a collision with Jasson Domínguez — no confirmed concussion, but day-to-day pending testing.
• WATCH — Brandon Nimmo (TEX, OF): sprained AC joint crashing into the wall; a possible IL stint pending Tuesday testing, per Skip Schumaker.
• ADD — Hunter Greene (CIN, SP): back with the team and lined up for his next rotation start after a clean rehab — add ahead of the announcement.
• HOLD — Eduardo Rodriguez (ARI, SP, 35% owned): six starts of 7-plus innings this year, dominant changeup — a borderline buy-low.

Semien out 4-6 weeks with a Grade 3 hip strain

HOLD · NYM · 2B

Marcus Semien (38% owned) was diagnosed with a Grade 3 hip flexor strain and is expected to miss four to six weeks minimum, per MLB Trade Rumors — the severity forced him to stop trying to play through it. It's one of the more significant mid-tier hits of the season. Ronny Mauricio (0% owned) becomes the Mets' primary option for everyday second-base reps.

Action: Move Semien to your IL slot; add Mauricio in deeper leagues for the 2B eligibility and playing time.

Chisholm in concussion protocol after an outfield collision

WATCH · NYY · 2B

Jazz Chisholm Jr. left Monday's loss to Detroit after a violent collision with right fielder Jasson Domínguez, both chasing a shallow popup; he's in concussion protocol, though Aaron Boone said he hasn't been formally diagnosed with a concussion, per the Associated Press. Oswaldo Cabrera finished at second. The injury adds to a banged-up Yankees lineup also missing Judge and Stanton (with Grisham and McMahon due back this week).

Action: Hold Chisholm in IL or bench spots; don't drop, and track the protocol updates daily — this is day-to-day for now, not a confirmed multi-week absence.

Nimmo's AC sprain may mean an IL stint

WATCH · TEX · OF

Brandon Nimmo sprained his left AC joint crashing into the right-field wall to record the final out Sunday at Toronto, and manager Skip Schumaker said he could require an IL trip pending Tuesday testing, per the Dallas Morning News. The Rangers already activated Evan Carter (for Wyatt Langford's hamstring IL), giving them some outfield cover.

Action: Hold Nimmo and await the imaging; if he lands on the IL, the Rangers' outfield depth (Carter and others) absorbs the reps rather than an obvious outside add.

Greene returns, lined up for his next start

ADD · CIN · SP

Hunter Greene is back with the Reds after a scoreless rehab assignment, with manager Terry Francona praising his readiness; the team will set his next rotation slot after meeting with the pitching staff. His return is a significant lift for a rotation trying to climb back into the race.

Action: Add Greene in all leagues and stash him for that next start; await the official date from Francona.

Eduardo Rodriguez keeps carving

HOLD · ARI · SP

Eduardo Rodriguez (35% owned) dominated San Francisco again, generating a 53% chase rate and a 38% whiff rate on his changeup. He now has six starts of seven-plus innings in 2026 — up from one all of last year — a real efficiency leap, per @JesseNFriedman.

Action: Hold, and target him in trades from owners who fear regression; he's a borderline buy-low at 35% owned.

Buxton's MRI shows hip impingement

WATCH · MIN · OF

Byron Buxton had an MRI that revealed right hip impingement; he's considered day-to-day, but the imaging confirms a structural concern worth watching, per the team. Hip issues can affect both his swing and his baserunning.

Action: Monitor his lineup status daily; if he starts getting rest days or DH-only appearances, that signals rising discomfort — have depth ready.

Arenado homers again against the Giants

HOLD · ARI · 3B

Nolan Arenado (19% owned) went 2-for-3 with a homer. He remains underowned relative to his track record, even with a quieter Statcast profile this year.

Action: A reasonable add in standard and deeper leagues for the steady production and lineup security.

Hao-Yu Lee stays hot despite a shoulder jam

HOLD · DET · 2B

Hao-Yu Lee doubled but jammed his right shoulder on a head-first slide, staying in and reporting he felt okay, per @cmccosky. He's 18-for-47 (.382) this month with the kind of at-bat-to-at-bat adjustments that suggest real improvement.

Action: Add in deeper leagues; monitor the shoulder for any post-game soreness, but the bat is trending up.

Contreras crushes a three-run homer

HOLD · BOS · C

Willson Contreras launched a three-run homer in the first at Fenway, another return on Boston's offseason additions, per @IanMBrowne.

Action: Hold; he's an everyday catcher with real power in a clicking lineup.

Caminero named AL Player of the Week

HOLD · TB · 3B

Junior Caminero was named AL Player of the Week, capping his power surge, per @BNightengale — recognition for one of the season's best young breakouts.

Action: Hold confidently; he's a rostered building block, not a waiver flier, with a secure everyday role.

Turner stays scorching with a leadoff bomb

HOLD · PHI · SS

Trea Turner homered leading off and is hitting .333 over his last 11 games, per @ToddZolecki — a key engine in the Phillies' surge.

Action: Hold confidently; he's in the middle of a strong run.

Arraez and Jung Hoo Lee anchor the Giants

HOLD · SF · 2B / OF

Luis Arraez (.324) and Jung Hoo Lee (.322) are the first teammates to hit .320-plus through a team's first 83 games since Blackmon and Arenado in 2019, per @BNightengale — the duo reigniting San Francisco's offense.

Action: Hold both; they're the backbone of the Giants' lineup.

Paddack traded to the Rangers

WATCH · TEX · SP

Chris Paddack was traded to Texas, per @JonHeyman — his rotation role should clarify over the next day.

Action: Monitor Paddack's first scheduled start with the Rangers before adding.

Grisham nears a rehab game and a return

WATCH · NYY · OF

Trent Grisham could play a rehab game and is eligible to return Wednesday or Friday, per The Athletic — adding a bat to a depleted Yankees outfield.

Action: Hold in IL spots; prepare to activate within 48 hours of his return.

Luis Robert begins a rehab assignment

STASH · CWS · OF

Luis Robert, out since April, begins a rehab assignment, per @AnthonyDiComo — a healthy Robert would reshape the White Sox outfield, though he's still weeks from the majors.

Action: Stash in dynasty and ultra-deep leagues; wait for a Triple-A stat line before promoting him.

Barger sidelined by a back stress reaction

WATCH · TOR · INF

Addison Barger, already rehabbing an elbow, now has a stress reaction in his back and will be shut down for a couple of weeks, per @KeeganMatheson — pushing his timeline into late July.

Action: Drop in shallow leagues; hold in an IL slot only if you can spare it.

Tanner Gordon set to start for Colorado

WATCH · COL · SP

Tanner Gordon completed a strong rehab outing and is expected to start against Miami, with Tomoyuki Sugano pushed back by a finger issue, per @harding_at_mlb.

Action: Monitor Gordon's line and workload; a streaming option only in deep formats given the Coors penalty.

Reds and Cubs bullpens take more hits

WATCH · CIN / CHC · RP

Tony Santillan (CIN) remains out with his oblique strain, and Anthony Banda landed on the IL with a lat strain. Separately, the Cubs are down Edward Cabrera, Ethan Roberts, and Hoby Milner, leaning on David Peterson and Colin Rea for rotation innings.

Action: Drop the injured relievers in standard leagues; Peterson and Rea are deep-league streaming options only when the matchups soften.
