The Arizona Diamondbacks have a very legitimate All-Star candidate in Ketel Marte, but one of their top offensive performers may be injured.

Marte singled home Jarrod Dyson in the bottom of the third inning on Friday and appeared to be hopping and favoring one leg as he ran down the line. 

Manager Torey Lovullo put infielder Ildemaro Vargas in as a pinch runner for Marte, ending the latter’s day. The team said Marte was removed with a left groin cramp and was day-to-day.

Any significant time missed for Marte would be a major loss for the D-backs, who already are coming off of being swept by the division-rival Rockies and entered Friday at an even 38-38, 13 games out of first place in the NL West and 2.5 games back of a Wild Card spot.

Coming into the game, Marte was hitting .205 with a whopping 20 home runs, 17 doubles, three triples, 50 RBI and a .932 OPS.

Marte’s home runs, RBI, slugging percentage, triples and hits all rank 12th or better in the National League.
