Triple-A Worcester reinstated Uberstine (shoulder) from its 7-day injured list Sunday.
Uberstine rejoins Worcester after he had been on the shelf for two months due to a sore right shoulder. The 27-year-old was activated after turning in a 5.14 ERA, 1.57 WHIP and 11:3 K:BB in seven innings over four rehab appearances for High-A Greenville.
