SCOTTSDALE, Ariz. (AP) Colorado Rockies hard-throwing righty Jon Gray left his spring training start in the third inning with soreness in his left foot.
The team said Friday it was for precautionary reasons.
Gray went 2 2/3 innings against San Francisco and gave up five runs before exiting the game. He could be the team's starter when the season opens April 3 in Milwaukee.
The third overall pick in 2013, Gray went 10-10 with a 4.61 ERA last season.
Colorado is already missing a starter with right-hander Chad Bettis stepping away from baseball to undergo chemotherapy after discovering that his testicular cancer had spread.
It's been an injury-filled spring training for the Rockies, who are without first baseman Ian Desmond (hand), outfielder David Dahl (ribs) and catcher Tom Murphy (forearm).
