Houston Astros

Carlos Correa

SS

It's worth noting that Correa will be starting at shortstop during his return to play -- something that may become more common while Jeremy Pena sits with a fractured finger. If Pena's absence extends into the regular season, Correa would slide back over to shortstop while Isaac Paredes starts at the hot corner.

Jeremy Pena

SS

Pena suffered the injury while playing in a World Baseball Classic exhibition game against Detroit on Wednesday. He will now likely miss the WBC, but his status for Opening Day will depend on how he checks out during his reevaluation in two weeks. If the 28-year-old ends up missing the first portion of the regular season, Nick Allen would be the next man up to start at shortstop for the Astros.

Cavan Biggio

1B

Biggio has been slow-played this spring as he works his way back from offseason arthroscopic surgery on his right elbow. The utility player is in camp as a non-roster invitee and his delayed start this spring surely eliminates any chance he had to make the Opening Day roster.

Enyel De Los Santos

RP

The right-handed reliever has been shelved by a right knee strain since the start of camp, but he will progress to mound work Saturday before being slotted into game action. Barring setbacks, De Los Santos is expected to have enough time to prep for Opening Day.

Josh Hader

RP

Hader developed left biceps inflammation before reporting to Astros camp and has been limited to flat-ground work since then. He also missed the final seven-plus weeks of last season with a left shoulder strain, so he hasn't pitched in a game setting since early August of last year. Hader is unlikely to have time to ramp up for Opening Day, setting up Bryan Abreu to serve as the Astros' early-season closer.
