34 A.J. Burnett, SP

Pirates starting pitcher A.J. Burnett suffered a Grade 1 calf tear and has been placed on the 15-day disabled list, the Pittsburgh Tribune-Review reports. 

Burnett is in a walking boot and has been unable to put weight on his leg as a result. Burnett said he hopes "it's not a six-week thing," but there is no clear timetable for his return. It's likely he will miss a month, if not more, with the injury.

The Pirates announced Thursday that starting pitcher A.J. Burnett has been placed on the 15-day disabled list, retroactive to June 9, with a right calf strain. He had already been scratched from his scheduled start Saturday.

Burnett is 4-6 with a 3.12 ERA, 1.13 WHIP and an NL-leading 99 strikeouts in 89 1/3 innings.

Pirates starter A.J. Burnett has been scratched from his start Saturday, according to the Pittsburgh Post-Gazette. 

Burnett is dealing with right calf pain, and is unable to make the start against the Dodgers. The club has not named a replacement starter yet, and there's no word on the severity of Burnett's injury. 

On the season, Burnett has a 3.12 ERA and a 3.32 FIP in 89 1/3 innings. 

Pirates starting pitcher A.J. Burnett was in peak form for much of Saturday's game against the Cubs, and the one mistake he made late did not prove costly, in a 6-2 win.

Burnett tossed eight scoreless innings to open the game, then allowed two runs in the ninth inning on a single and a two-run home run by Alfonso Soriano. He limited the Cubs to just the two runs on four hits and three walks, in his longest outing of the season.

Burnett struck out five batters while throwing 77 of 112 pitches for strikes. He pushed his record to 4-6 on the season, while lowering his ERA to 3.12. He is scheduled to make his next start Thursday against the Giants.
