• Barring rainouts or rotation changes, ex-Giants right-hander Ryan Vogelsong will face his former teammates Aug. 15 when Pittsburgh visits San Francisco.
Vogelsong, who spent the previous five seasons with the Giants, left the 60-day disabled list to start for the Pirates in Atlanta on Thursday. He had been sidelined since May 23, when he was hit in the face by a fastball and sustained multiple facial fractures.
Vogelsong excelled in his return, allowing one run on three hits and striking out six in six innings.
