Houck (elbow) allowed two runs (one earned) on two hits while striking two over 3.1 innings for Triple-A Worcester on Saturday.
This was Houck's fourth and final rehab outing, and he could rejoin the team next week. He didn't have enough time to build up as a starter, but Houck could be an option out of the bullpen during a six-game home stand to wrap up the regular season.
