Houston Astros All-Star shortstop Jeremy Pena will return to the injured list with a mild left calf strain, manager Joe Espada announced following Monday's 5-4 loss to Minnesota. Pena sat out the game as Nick Allen took over at shortstop, marking another setback for the team's infield defense.

Pena had already missed time earlier this season dealing with a right hamstring strain, making durability a concern for the 26-year-old infielder. The Astros are now without their starting shortstop for at least the minimum 10-day stay, with Espada suggesting the injury won't require an extended absence.

Through his limited action this year, Pena has maintained solid production at the plate, batting .291 with six home runs and 21 RBIs. His absence creates a significant gap in Houston's lineup while they attempt to remain competitive in the AL West race.

Nick Allen will likely handle shortstop duties while Pena recovers, though his offensive contributions don't match Pena's consistency. The Astros need their All-Star back quickly to maintain playoff positioning as the season enters its critical second half.
