Matheny added that it happened on a swing, but was a different area on the same thumb which caused him to miss the first two months of the season after he had surgery on it. He injured the thumb in Spring Training fielding a ground ball and returned on June 7 after missing 57 games.
Matt Carpenter played 51 games at third base in Peralta's absence while Kolten Wong started a majority of the games at second base. Since his return, Carpenter has moved to second base while Wong has been optioned to Triple-A and then recalled to play center field.
