OAKLAND, Calif. -- Boston Red Sox reliever Bobby Poyner pitched a perfect seventh inning for Triple-A Pawtucket vs. Gwinnett in his second rehab outing today.

The Red Sox placed Bobby Poyner on the 10-day disabled with a left hamstring strain April 12.

The Red Sox possibly could activate him when they open a three-game series against the Blue Jays at Rogers Centre on Tuesday.

He retired the side on a groundout to first base, a flyout to right field and strikeout (looking).

The 25-year-old Poyner, who made the Red Sox's Opening Day roster despite never pitching above Double A, allowed only two runs in 7 innings (2.57 ERA) over six relief outings before landing on the DL.
