Beede (groin) is expected to miss the rest of the season, Alex Pavlovic of NBC Sports Bay Area reports.
It's unfortunate timing for Beede, who was expected to be a late-season call-up for the struggling Giants but instead departs for the team's spring training facility in Arizona to begin rehab. The prospect suffered a groin injury while warming up for a start with Triple-A Sacramento, where he owns a 4.79 ERA over 19 starts this season. There still remains a possibility Beede could be back by late September, though it appears he's more likely to make his next appearance in the upcoming Arizona Fall League.
