After hitting a single to start the 11th inning, LaRoche then suffered the injury while advancing to second base on a sacrifice bunt by pinch-hitter Jordan Zimmermann. LaRoche was then seen wiggling his leg before manager Jim Riggleman and assistant Michael McGowan came to his aid. LaRoche left the game soon after that.
LaRoche said he had problems with the groin on a check-swing in the fourth inning.
"I kept stretching it as the game went on and started to feel it more and more," LaRoche said. "It didn't feel great running to second."
It marks the second injury LaRoche has suffered this season. He is currently nursing a slight tear to his left rotator cuff.
"It's really frustrating. Looking back the last couple of years, I had some little things like this early," LaRoche said. "Luckily, it kind of ironed themselves out and then I felt OK the rest of the way. Hopefully that is the case."
