Besides catching what is perhaps the best pitching staff in baseball, Posey put up some serious numbers in only 108 big league games with the Giants this year: .305 avg., 67 RBI, 23 doubles, 2 triples, and 18 home runs. He helped lead the Giants to their first San Francisco World Series title, and the first franchise Series win in 56 years.
Posey was followed in the Rookie of the Year voting by Phillies outfielder Jason Heyward (.277/72 RBI), St. Louis starter Jaime Garcia (13-8, 2.70 ERA), Florida Marlins first baseman Gaby Sanchez (.273/85 RBI), and Pittsburgh Pirate second baseman Neil Walker (.296/66 RBI).
Fireballing closer Neftali Perez (42 saves) of the Texas Rangers won the 2010 American League Rookie of the Year Award.
Buster Posey was called up from Triple A Fresno by the Giants front office on May 29, 2010, after hitting .349, with a .442 on-base percentage and a .995 OPS with the minor league team. Many observers were stunned when Posey was not part of the Giants team following Spring Training 2010, when he batted .315 with a .351 OBP. The Giants selected Posey in the first round (5th pick overall) of the 2008 amateur draft.
