Although Ruiz's offensive numbers as a whole were not particularly impressive over his 10-plus seasons in Philadelphia (68 homers, 401 RBI, .266 batting average), his impact was felt in many different facets of the game. He caught four no-hitters during his tenure with the Phillies- including Roy Halladay's perfect game and postseason no-hitter- and threw Brandon Phillips out at first base to finish off the postseason no-no. When Halladay won the NL Cy Young Award in 2010, he gave Ruiz an exact replica of the trophy because of the impact he had by calling games so well.
Of course, Ruiz will be remembered in Philadelphia for being an integral part of the 2008 World Series champion team. Without him, it's possible that Brad Lidge wouldn't have gone a perfect 48-for-48 (including going 8-for-8 in the postseason). In Game 3 of that series, Ruiz hit a walk-off infield single, swinging the series in the Phillies' direction. They didn't drop another game that series.
