Posey, Davis named Rookies of the Month

Giants catcher wins NL award; Rays pitcher wins in AL

Giants catcher Buster Posey, whose 21-game hitting streak was one of the longest by a rookie in Major League Baseball history, and Tampa Bay right-hander Wade Davis, who won all four of his decisions during July, have received the Gillette presents the Rookie of the Month Award for their respective leagues.

Posey was voted the National League Rookie of the Month Award winner after leading the league with 43 hits during July, which translated to a .417 average that sparked the Giants' charge toward the top of the NL West.

Having previously earned overall NL Player of the Month honors for July, the Georgia native becomes the first player to double in the awards since Milwaukee's Ryan Braun, in July 2007.

Posey's 43 hits set a new one-month San Francisco rookie record, and his 24 RBIs matched another club one-month standard for rookies set by Jim Ray Hart in 1964.

Posey's 21-game hitting streak, spanning July 4-29, fell one short of the San Francisco record for rookies established in 1959 by Hall of Fame first baseman Willie McCovey.

The scintillating month jacked Posey's season average to .356, which leads all NL rookies. So does his on-base percentage of .399 and his slugging percentage of .538.

Posey dominated the month so pervasively among NL rookies that the only other player to receive votes for the award was St. Louis outfielder Jon Jay, who batted .431 and drove in 11 runs.

Davis, the first pitcher to earn the American League Rookie of the Month Award in 2010, went 4-0 with a 3.03 ERA in five July starts. The fourth player in Tampa Bay history to be voted as Rookie of the Month, the 24-year-old Florida native punctuated his breakout July by hurling seven innings in a 3-2 victory over the Yankees on July 30 that put the Rays in position to supplant New York atop the AL East standings.

Davis' total of nine wins tops AL rookies and already ranks fifth on Tampa Bay's all-time list of rookies winners, trailing Rolando Arrojo (14 in 1998), Jeff Niemann (13 in 2009), Scott Kazmir (10 in 2005) and David Price (10 in 2009).

Other AL rookies receiving strong support in balloting for the awards included Davis' teammate, second baseman Reid Brignac (4 homers and 11 RBIs); Minnesota third baseman Danny Valencia (.453 with 11 RBIs); Tigers outfielder Austin Jackson (.314); and White Sox first baseman Dayan Viciedo (.348).
