Braves reliever David Carpenter struck out all three batters he faced in the second game of his injury-rehab assignment Monday and is expected to come off the 15-day disabled list Wednesday, the first day he’s eligible.

On the DL recovering from a strained right biceps muscle, Carpenter threw 10 strikes in 13 pitches in the first inning for Triple-A Gwinnett on Wednesday, striking out the side. The hard-throwing Braves setup man has four strikeouts and no walks in two hitless innings of two appearances for Gwinnett.

“He pitched really well, 1-2-3 inning, felt good,” Braves manager Fredi Gonzalez said of Monday’s outing. “I’m sure he’ll come back today or tomorrow and get reevaluated, reassessed and see where he’s at. But the way he pitched, the way he felt before he left — he felt great, so I don’t see any reason why (he wouldn’t be activated) when he’s eligible.”
