Texas recalled Curvelo from Triple-A Round Rock on Sunday.

Curvelo wasn't able to break camp with the Rangers, but he'll now get a look in the bullpen after Carter Baumler landed on the 15-day injured list Sunday due to a right intercostal strain. In his first big-league stint last season, Curvelo tossed 19 innings over 17 appearances and posted a 5.68 ERA, 1.42 WHIP and 20:10 K:BB while picking up two holds. He'll likely take on a low-leverage role.

Ballesteros is out of the lineup for the first game of Sunday's doubleheader against the Guardians.

Ballesteros will hit the bench for a third straight game after he started the first five contests of the season. The previous two absences came against a lefty starter, but right-hander Slade Cecconi is taking the ball for Cleveland in the first game of Sunday's twin bill. Alex Bregman is resting his legs but staying in the lineup at designated hitter while Matt Shaw handles the hot corner.

The Rangers placed Baumler on the 15-day injured list Sunday due to a right intercostal strain.

Baumler had his best outing of the season Saturday versus Cincinnati, striking out one batter in one perfect inning, but he apparently was injured in the process. The right-hander will consequently need to miss at least a couple weeks. Texas recalled reliever Luis Curvelo from Triple-A Round Rock to take Baumler's place in the bullpen.

Toronto optioned Little to Triple-A Buffalo on Sunday.

Little has had a disastrous start to the campaign, allowing 10 earned runs and giving up three homers while posting a 6:3 K:BB over 3.2 innings across five appearances. He was a big piece of the team's bullpen while working in a high-leverage role last season, so Little will presumably be given another chance with the big-league club if he's able to work out his issues with Buffalo. The Blue Jays selected the contracts of two relievers -- Austin Voth and Joe Mantiply -- among a series of transactions Sunday.

Toronto optioned Estrada to Triple-A Buffalo on Sunday.

Estrada was excellent in a bulk-relief outing Saturday, holding the White Sox hitless over four innings while striking out three batters and walking two. However, he threw 66 pitches and would presumably be sidelined for several days as a result, so the Blue Jays opted to shuffle him down to Buffalo in order to beef up the team's bullpen. Given Estrada's performance Saturday, it seems very likely he'll be back with the major-league club relatively soon.

Toronto selected Voth's contract from Triple-A Buffalo on Sunday.

After Voth was released by the White Sox on March 20, the Blue Jays scooped him up on a minor-league contract. In one start with Buffalo this season, the right-hander tossed three innings, allowing two earned runs on two hits and no walks while striking out two batters. Voth has worked both as a starter and a reliever during his time in the majors, but given that Toronto stated that he'd be available to pitch Sunday, it appears he's slated for a bullpen role.

The Pirates recalled Cook from Triple-A Indianapolis on Sunday, Kevin Gorman of TribLive.com reports.

The 27-year-old was sent to Indianapolis on Thursday but will quickly return to the majors with Jared Triolo (knee) landing on the injured list. Cook made the Pirates' Opening Day roster but registered just six plate appearances during the first week of the season, and he's unlikely to have a significant role while Pittsburgh's outfield is in good health.

The Blue Jays selected Mantiply's contract from Triple-A Buffalo on Sunday.

Mantiply signed a minor-league contract with Toronto in early March, but he wasn't able to crack the Opening Day roster. The veteran reliever thus began the campaign with Buffalo, pitching in two games and allowing one run while posting a 3:0 K:BB over 3.2 innings. Mantiply should occupy a low-leverage spot in the Blue Jays' bullpen. The team was able to clear room for him on the 40-man roster by transferring Cody Ponce (knee) and Anthony Santander (shoulder) to the 60-day IL.

The Dodgers recalled Kim from Triple-A Oklahoma City on Sunday, Sonja Chen of MLB.com reports.

Mookie Betts landed on the injured list with an oblique strain, so Kim will join the Dodgers to split playing time at shortstop with Miguel Rojas. Kim missed out on Los Angeles' Opening Day roster in order for him to get everyday reps at Triple-A, but he'll now have a chance at a regular role in the majors. In his first taste of the big leagues last season, he posted a .280/.314/.385 slash line with three homers, 13 steals, 17 RBI and 19 runs in 71 games.

Toronto transferred Santander (shoulder) from the 10-day injured list to the 60-day IL on Sunday.

The move was fully expected at some point in 2026 after Santander underwent shoulder surgery in February. The veteran outfielder could return later in the season, though he's almost certain to be out at least through the All-Star break. The Blue Jays opened up a spot on their 40-man roster, which will likely to used to bolster an injury-depleted pitching staff.
