Pena went 2-for-4 with a double and two runs scored Monday against the Tigers.

Pena led off Sunday, though that came against a lefty and with Jose Altuve on the bench. It was more noteworthy that he was in the same spot Monday, with Altuve hitting second in the order. While there are plenty of bigger names in the Houston lineup, Pena has been a steady producer and has increased his walk rate to 7.9 percent while getting on base at a .333 clip through 114 plate appearances.

Allen went 3-for-4 with an RBI in Monday's win over the Rockies.

The 26-year-old led Atlanta in hits on a night when the team took advantage of Coors Field to rack up 14 knocks in total. Allen remains a glove-first shortstop, but he's provided more offense than expected this season to supplant Orlando Arcia as the starter, slashing .292/.352/.338 through 21 games with four steals, four RBI and seven runs.

Rockies manager Bud Black said Monday that Tovar (hip) is "not progressing as we'd hoped" and still might be 7-to-10 days away from being activated from the 10-day injured list, Patrick Lyons of JustBaseball.com reports.

Tovar is working his way back from a left hip contusion, and Black said that the shortstop is having problems hinging his hips when fielding grounders. The Rockies had been expecting Tovar to return to action at the beginning of May, but he will need a little more time than that. With Aaron Schunk (groin) also recently landing on the IL, the Rockies have been using Kyle Farmer and Alan Trejo at shortstop.

The Cardinals optioned Saggese to Triple-A Memphis on Monday.

Saggese has slashed .341/.364/.512 in 14 games this season at the major-league level, but his playing time has dipped since Masyn Winn returned from the injured list last week. Jose Barrero is grabbing Saggese's roster spot while the latter returns to Memphis where he can play every day.

Nimmala went 2-for-5 with a solo home run and two additional runs scored for High-A Vancouver on Sunday.

It was the 19-year-old's third straight game leaving the yard. Nimmala has taken a big step forward at the plate to begin the campaign, slashing .289/.349/.539 through 18 games and reducing his strikeout rate from 31.8 percent in 2024 to 21.7 percent through his first 83 plate appearances this season. Despite his age, the Blue Jays will have to consider a promotion to Double-A for Nimmala at some point this summer if he continues to thrive against Northwest League pitchers.

The Cardinals selected Barrero's contract from Triple-A Memphis on Monday.

He'll join the 26-man active roster as a replacement for Thomas Saggese, who was optioned to Memphis. After he was unable to win a spot on the Cardinals' Opening Day roster as a utility player, Barrero earned his promotion to the big leagues by slashing .299/.396/.517 with four home runs and four stolen bases over 23 games at Triple-A. The right-handed hitting Barrero has seen most of his professional action in the infield but could end up serving as a short-side platoon mate for Victor Scott in center field.

Nunez is out of the lineup for Monday's game against the Mets.

Nunez made nine straight starts from April 14 through this past Wednesday, but he's since shifted to the bench following top shortstop CJ Abrams' return from the injured list Thursday. So long as Abrams remains healthy, Nunez is expected to see infrequent opportunities as a utility infielder.

The Red Sox will promote Arias from Single-A Salem to High-A Greenville this week, Chris Cotillo of MassLive.com reports.

After a stellar run in the Florida Complex League last summer, Arias received a taste of the Carolina League late in the 2024 campaign before returning to Salem to begin 2025. He hit .346/.407/.397 with four stolen bases in 86 plate appearances with Salem this season, and the Red Sox determined the 19-year-old infielder was ready for a tougher test.

The Cardinals are expected to option Saggese to Triple-A Memphis prior to Monday's game against the Reds, John Denton of MLB.com reports.

In a corresponding move, St. Louis intends to call up Jose Barrero, who will provide the bench with more versatility due to his ability to play center field in addition to multiple infield spots. Saggese had gone 0-for-6 with a pair of walks while manning second base in both of the Cardinals' last two games, but playing time had been elusive before that for the 23-year-old, who hadn't started in any of the preceding four contests. He'll get a chance to play on an everyday basis in Memphis and should rank near the top of the list for a call-up the next time the Cardinals require an extra infielder.

Walls went 1-for-4 with a solo home run in Sunday's win over the Padres.

Walls got the Rays on the board with a solo home run to center field. It was his first home run and first extra-base hit of the season. He's now driven in a run in consecutive games but is hitting just .164/.260/.209 with six RBI, nine runs scored and a 9:19 BB:K in 77 plate appearances.
