Grandal was removed from Tuesday's game against the Giants due to left groin discomfort, Andrew Destin of the Pittsburgh Post-Gazette reports.
Advice: After going hitless in his first three at-bats of the night, Grandal doubled and came around to score during Pittsburgh's ninth-inning rally, but he was unable to catch in the top of the 10th inning. The severity of his injury isn't immediately apparent, but the Pirates should have more information on the veteran backstop's injury before the start of Wednesday's game.
