From the Giants website:
Left-hander Noah Lowry pitched at Class A San Jose on Friday night in what Giants head trainer Stan Conte called a "real test." Lowry had an 85-pitch limit, and how he comes out of the outing will determine when he can rejoin the rotation.

"If he gets to 85 pitches, we can look at a five-day rotation," Conte said. "On paper that means Wednesday, probably in [Triple-A] Fresno, but that hasn't been decided yet. [Friday night] is the real test for me in regards to the injury. If he pitches another rehab, that's more for baseball purposes."

Against the High Desert Mavericks, Lowry went 4 2/3 scoreless innings, allowing five hits and one walk while striking out nine. He has been on the 15-day disabled list since April 7 with a right oblique (side) strain. He was the only Giants pitcher to make all 33 of his starts last year.
