Input: Question: Which of the two catchers Feliz replaced is the oldest when Feliz played catcher for the first time in his major league career? Passage:On June 8, 2007, in a game against the Oakland Athletics, Feliz played catcher for the first time in his major league career. During that game, the Giants' starting catcher Bengie Molina was lifted from the game, as part of a double switch. Their backup catcher, Eliézer Alfonzo, was injured on a play at the plate and had to leave the game, in the 10th inning. With the Giants out of position players, Feliz moved to catcher, Randy Winn moved from center field to third, Dan Ortmeier moved from right field to center, and pitcher Noah Lowry came into the game in right. After the season, Feliz was honored with a Fielding Bible Award as the best fielding third baseman in MLB in 2007.
