LeMahieu, the team's regular No. 2 hitter behind Charlie Blackmon, went 0-for-4 Saturday but is hitting .394 over his last 37 games, second in the Majors to the Astros' Jose Altuve during that span. He tweaked the injury during his final at-bat.
"It just didn't feel as good this morning as I thought it would. It felt weak," said LeMahieu, who has Monday's day off to heal further before a two-game set in Cleveland begins Tuesday night. "It'll be fine."
LeMahieu, the defending National League batting champ and an All-Star this year, has overcome a slow offensive start to build a .319 batting average through 105 games. He's hitting .324 with a .387 on-base percentage in 53 games at Coors Field, and hitting .314 with a .387 OBP on the road.
