Rockies' Jon Gray leaves spring training start with apparent injury

Colorado Rockies starting pitcher Jon Gray left three batters into the team's Cactus League game against the Milwaukee Brewers on Tuesday with an apparent injury.

Gray made an errant throw to second base on a comebacker off the bat of Brewers catcher Jonathan Lucroy and was immediately pulled from the game by Rockies manager Walt Weiss. The rookie right-hander was having his hand checked out upon exiting the field, according to witnesses at the ballpark. The game is not televised and specifics have yet to be reported by credible sources attending the game.

Gray did not record an out, surrendering a leadoff double to Scooter Gennett and a walk to Ramon Flores prior to Lucroy's at-bat. The Brewers scored two runs in the inning with Christian Bergman on the mound. Both runs were charged to Gray, but only one was earned.

It has been an up-and-down spring for the 24-year-old Gray, who enters the 2016 season as a probable candidate for the middle of the Rockies' rotation. He entered the game with a 3.09 Cactus League ERA and was good his last time out -- four scoreless innings with three strikeouts and a walk -- after a rough start. Gray was hitting 97 mph on his fastball before the injury occurred, per Patrick Saunders of The Denver Post.

UPDATE: Gray left the game with abdominal tightness, according to the Rockies on Twitter:
