Giants’ injured prospects ‘missing important playing time’ Joan Gregorio was suspended for testing positive to performance-enhancing drugs. All had chances for serious big-league time, especially with the Giants buried in the cellar. “It would’ve been nice to have kept these guys healthy, not just for here but in Sacramento, to continue their development,” manager Bruce Bochy said. Pitcher Tyler Beede was scratched 15 minutes before his start with Triple-A Sacramento with a strained groin. Beede was the Giants’ top draft pick in 2014 and seemed destined for a call-up this season. Bochy mentioned Jarrett Parker and Mac Williamson as other players missing time with injuries. Parker won a platoon job in left field out of spring training but played just nine games before he got hurt. “We’ve had so many guys who are missing important playing time,” Bochy said. Johnny Cueto, on the disabled list with blisters on his fingers, played catch and will throw again Tuesday.
