PHOENIX -- Already saddled with concerns involving the overall health of their starting rotation, the Giants absorbed more worries Tuesday as first baseman Brandon Belt strained his right groin and left the game.
Stuck with an undermanned bench due to the necessity of carrying 13 pitchers, one more than usual, the Giants had to decide quickly whether to place Belt on the disabled list or allow him to play through his discomfort.
"Honestly, I don't think it's too bad," Belt said after the Giants' 7-6 loss to the Arizona Diamondbacks. "It's a little frustrating, but I'm pretty optimistic about doing what I have to do to get back out there."
However, Belt admitted that moving from side to side, a requirement for any first baseman, would be a challenge.
The Giants have personnel options if Belt goes on the disabled list. Recalling Adam Duvall from Triple-A Sacramento is one possibility. A less likely scenario would involve recalling Sacramento catcher Andrew Susac and playing Buster Posey at first.
Under normal circumstances, the Giants could install Travis Ishikawa at first base. But Ishikawa is on the disabled list with a back injury and cannot be activated until April 14.
Tuesday, Joaquin Arias initially replaced Belt, though first base is the infield spot the utility man has played the least. By the fifth inning, Posey was at first base, leaving Hector Sanchez to catch.
Belt injured himself while pursuing Nick Ahmed's foul popup in the fourth inning.
