Astros manager Joe Espada said Pena (hamstring) is expected to begin a minor-league rehab assignment Tuesday or Wednesday, Matt Kawahara of the Houston Chronicle reports.
Analysis:
The 28-year-old shortstop ran the bases with no issues this weekend, which was the final hurdle in his rehab program before playing in games. Pena shouldn't require a lengthy rehab assignment and could be back with the Astros next weekend or early the following week.
