OAKLAND – Astros catcher Jason Castro, who has been on the 15-day disabled list with a right quad strain since Aug. 29, started light running exercises on a treadmill this week.
Barring a setback, Castro will move behind the plate within the next two days to catch situational lefthander Tony Sipp’s bullpen session at Minute Maid Park.
Sipp, who has been out with a back ailment, and Castro remained behind in Houston during the Astros’ three-game series against the A’s. They’re expected to rejoin the club in Anaheim for the three-game series against the Angels, A.J. Hinch said.
