The Opener: deGrom, Murakami, Debuts

Here are three things we’ll be keeping an eye on around the baseball world today:

1. deGrom still waiting for season debut:

Rangers veteran Jacob deGrom was slated to make his season debut over the weekend, but was scratched from his scheduled start due to a neck issue. Via Shawn McFarland of the Dallas Morning News, manager Skip Schumaker indicated that deGrom could still make his first start of the year during the club’s current series in Baltimore. Righty Jack Leiter has already been announced as today’s starter, but deGrom could start tomorrow’s game against Orioles righty Zach Eflin or pitch Wednesday versus lefty Trevor Rogers. The 37-year-old deGrom enjoyed his first full season of the decade in 2025, making 30 starts for the first time since winning the NL Cy Young Award in 2019. The righty’s 2.97 ERA and 3.64 FIP weren’t quite the same level as his peak, but that’s still clearly front-of-the-rotation production the Rangers are counting on as they look to return to the playoffs this year.

2. Murakami kicks off MLB career with homer streak:

Longtime NPB slugger and current White Sox rookie Munetaka Murakami exploded onto the stateside scene over the weekend, hitting home runs in three consecutive games against the Brewers to kick off his MLB career. The corner infielder took a deal well below expectations with Chicago due to concerns about his contact rate and defensive ability. Those concerns will take a lot more than one series to fade, but there was never any doubt about his prodigious power. That’s absolutely played so far, and when the White Sox head to Miami to face Chris Paddack (5.35 ERA in 2025) Murakami will look to extend his career-opening homer streak to four games. That game is scheduled to take place at 6:40pm local time in Miami this evening, with Davis Martin (4.10 ERA in 2025) set to take the mound opposite Paddack.

3. Key starters making team debuts:

As the first turn through the rotation of the 2026 season continues, a number of impact starters will make their first starts with new teams today. Cubs right-hander Edward Cabrera (3.53 ERA in 2025) will take on the Angels at 6:40pm local time in Chicago, while the Red Sox will send southpaw Ranger Suarez (3.20 ERA in 2025) to the mound against the Astros at 7:10pm local time in Houston. Ryan Weathers (3.99 ERA in eight starts last year) will make his Yankees debut against the Mariners at 6:40pm Seattle time, while Paddack (Marlins), Walker Buehler (Padres), Nick Martinez (Rays), and Kyle Harrison (Brewers) are among the other starters making team debuts. It’s not quite a team debut, but Justin Verlander (3.85 ERA in 2025) is slated to make his first start for the Tigers since 2017 at 7:10pm local time in Phoenix against Diamondbacks righty Michael Soroka (who is making his own debut for the Snakes).
