Not good. Eflin is presumably headed for an MRI to determine whether he’s dealing with any structural damage and appears ticketed for the injured list, even if this isn’t a worst-case scenario. The 31-year-old veteran hurler looked sharp in his season debut, recording seven strikeouts while limiting the Rangers to just one run on four hits over 3 2/3 innings. There should be a definitive update on his status at some point in the coming days. Dean Kremer would be the logical choice to fill Eflin’s spot in Baltimore’s rotation.

The long-term agreement, first reported earlier Tuesday, is now official. Emerson is widely regarded as one of the top prospects in baseball and is expected to be a key piece of Seattle’s roster through at least 2033. The 20-year-old prodigy’s combination of bat-to-ball skills and emerging power makes it easy to envision him as an impactful fantasy contributor in the near future. There has been no indication the Mariners plan to accelerate his timeline at Triple-A this season, but his arrival as the club’s shortstop of the future feels almost inevitable, especially since J.P. Crawford hitting free agency at the end of the year.

Heyman did not provide specifics regarding a potential extension offer from the Cardinals to Wetherholt, who is hitting .250 (4-for-16) with one homer and one steal through his first four games in the majors. Still, it would make sense for both sides to explore a deal early in his rookie season, similar to the extensions the Red Sox and Orioles reached with top prospects Roman Anthony, Kristian Campbell and Samuel Basallo last year. This report follows Seattle’s decision to sign top prospect Colt Emerson to an eight-year, $95 million contract earlier on Tuesday.

Blue Jays manager John Schneider said that Ponce will miss significant time, but the club remains hopeful he’ll pitch again this season and will await additional medical opinions before determining his next steps. The 31-year-old journeyman left his Blue Jays debut on Monday night with right knee discomfort before an MRI revealed an ACL sprain in his right knee. His prolonged absence puts additional strain on Toronto’s rotation which is already without Trey Yesavage (shoulder), Shane Bieber (elbow) and José Berríos (elbow).

The McGonigle era has gotten off to a phenomenal start with Detroit’s top prospect hitting .357 (5-for-14) with two doubles and four RBI through four games. Perhaps the most impressive aspect of the 21-year-old hitting machine’s early-season performance has been his plate discipline, as he’s struck out just three times while also drawing three walks. He’s batting second for the first time on Tuesday night at Chase Field after hitting sixth at the outset of the year.

Raleigh was given a day off initially, but he came off the bench to deliver his best moment of the young season. He laced an inside fastball from Paul Blackburn with a runner on third into right, and it gave Seattle a 2-1 lead. Raleigh has gotten off to a slow start, but it’s far too early to panic, and Monday is an example of what the man they call Big Dumper can do.

Harrison generated a career-high 16 swinging strikes and needed an economical 87 pitches (64 strikes) to navigate five frames in his Milwaukee debut. A leadoff homer by sizzling-hot Rays slugger Yandy Díaz accounted for all of the damage against him. The 24-year-old former top pitching prospect continues to impress, aided by increased fastball velocity and the addition of a new kick changeup. He should be rostered in all fantasy formats based on his recent performance and strikeout upside. He’ll face the Royals on the road to close out a two-start week on Sunday afternoon.

Cabrera was staked to a six-run advantage by the fourth inning of his Cubs debut and had little trouble cruising to an easy win, scattering one hit and one walk over six relatively stress-free frames. Chicago’s big-time offseason trade acquisition generated 15 swinging strikes, topped out at 98.1 mph with his fastball and allowed just two hard-hit balls in this one. He’ll close out a two-start week with a favorable road tilt against the Guardians.

Acuña picked up his first steal of the season, but was also caught for the only negative to the contest. The 28-year-old scuffled in the series against Kansas City, but those two hits along with two free passes improves his slash to .214/.353/.286 over the first four contests.

He’ll undergo further evaluation and imaging to determine the severity of the injury. It’s an ominous injury designation after Ponce was carted off during his Blue Jays debut following an awkward attempt to field a grounder up the first-base line in the third inning of his first major-league appearance since 2021. The 31-year-old journeyman spent the previous four seasons overhauling his arsenal in Korea and Japan before returning stateside on a three-year, $30 million deal with Toronto. An extended absence would be a significant blow to an already injury-ravaged rotation that’s without Trey Yesavage (shoulder), Shane Bieber (elbow) and José Berríos (elbow). An update on his status should arrive in the coming days, but he’s in clear jeopardy of missing his next scheduled start against the White Sox on Sunday.
