Pena (calf) is expected to play in a couple of rehab games at Triple-A Sugar Land this week could return from the 10-day injured list during the Astros' final series before the All-Star break next weekend against the Rangers, Chandler Rome of The Athletic reports.
The veteran shortstop landed on the shelf last Tuesday due to a calf strain, but his absence looks like it will end up being a brief one. Pena was swinging a hot bat prior to getting hurt, having gone 8-for-21 with two walks, three RBI and five runs in his last five games.
