Where do SF Giants turn after Blake Snell's 'frustrating' second injury?

Bob Melvin gave it some thought and did the math. “So, that's five,” the Giants manager said, finishing his answer to a reporter's question Monday afternoon before his team opened a three-game series against the Diamondbacks at Chase Field. As in, five healthy starting pitchers, a figure Melvin could only claim by including the pitcher expected to take down bulk innings in relief that night, Spencer Howard, and looking ahead to the anticipated return of one full-time member of the rotation, Keaton Winn. Winn has made enough progress on his way back from forearm tightness to warrant a seat on the team charter this trip — he could be an option if all goes well in a rehab outing scheduled for Tuesday at the Giants' minor-league complex — but the loss of Blake Snell means the Giants' rotation won't return to full strength anytime soon.
