Jason Castro was continuing his recent success at the plate after hitting a ball that was a guaranteed double during the Houston Astros versus Minnesota Twins game in the sixth. As Castro was rounding first and almost to second base, he started grabbing at his right hip and limped the rest of the way to second base. He was in obvious pain as he walked off the field and down the dugout tunnel. It was later announced and confirmed by manager A.J. Hinch after the game as a hip flexor or quad area injury.
