Milwaukee Brewers catching prospect Jeferson Quero is making his major-league debut on Sunday against the visiting Chicago White Sox and left-hander Anthony Kay. Quero will do the catching for right-hander Brandon Sproat and will bat seventh. The Brewers surprisingly called up Quero to the big-league roster on Saturday from Triple-A Nashville to help give them more depth with first baseman Andrew Vaughn (hand) going on the 10-day injured list. The 23-year-old Quero will help fill in behind the plate with William Contreras serving as the designated hitter in the series finale against Chicago. Quero is the Brewers' top catching prospect. His development has been slowed in recent seasons due to various injuries, including hamstring and shoulder issues in 2025. Quero is still considered one of the best defensive backstops in the game. However, he could struggle with the bat early on in his first taste of big-league pitching. He slashed .255/.3336/.412 with six homers and 44 RBI in 58 games at Nashville in 2025.

Texas Rangers right-hander Jacob deGrom (neck) said his stiff neck feels "much better" on Sunday, according to Kennedi Landry of MLB.com. deGrom played catch from 120 feet, which he couldn't do on Saturday before he was scratched from his first start of the 2026 season against the Philadelphia Phillies. The veteran hurler still feels it a bit, but he's hopeful that he can start in Baltimore against the Orioles this week. deGrom woke up Saturday morning with a stiff neck, and the Rangers decided not to take any chances with the oft-injured 37-year-old veteran. If the two-time Cy Young winner is cleared to take the ball for his first start of the year, it will likely come on either Tuesday or Wednesday at Camden Yards. deGrom was an All-Star for the fifth time in his career in 2025 and made 30 starts, but from 2021 to 2024, he made a total of just 35 starts for the Mets and Rangers due to injuries. He'll be a bit riskier against Baltimore if he ends up starting this coming week.

Houston Astros shortstop Jeremy Pena is back in the starting lineup for the team's series finale on Sunday against the division-rival Los Angeles Angels, batting out of the leadoff spot against right-hander Jack Kochanowicz. Pena did not play in the Opening Day loss on Thursday while recovering from a fractured finger that he suffered earlier this spring while preparing for the World Baseball Classic, but he returned on Friday to go 2-for-5 with a run scored and a double before resting again in the team's win on Saturday. With Pena back in there, Carlos Correa will move back to third base, and Isaac Paredes will start at second base. Jose Altuve will serve as the designated hitter. The Astros are being careful not to overwork Pena early in the regular season, but his outing on Friday proved that his finger issue shouldn't be a problem when it comes to hitting. Fantasy managers in redraft leagues will want to get him back in their starting lineups on Sunday. Pena has one hit in just two career at-bats against Kochanowicz.

Athletics outfielder Lawrence Butler is not in the starting lineup for Sunday's contest against the Toronto Blue Jays. Butler started Opening Day but hasn't played since then. It's unclear if his absence is related to his pre-season knee injury or the fact that the A's have faced a left-handed pitcher on back-to-back days. Butler went 0-for-3 in his lone appearance back on Friday. He's coming off a suboptimal 2025 season in which he slashed .234/.306/.404 with 21 home runs, 22 stolen bases, and 96 wRC+. It will be interesting to see if Butler comes off the bench Sunday and if he gets into the lineup against Braves right-hander Bryce Elder on Monday. If not, it will be safe to assume that his knee injury is lingering into the regular season.
