Major League Baseball Tuesday announced the eight All-Stars who will compete in the 2011 Home Run Derby on Monday, July 11th at Chase Field in Phoenix. The two most recent champions of the event, David Ortiz of the Boston Red Sox and Prince Fielder of the Milwaukee Brewers, will serve as the captains for the American League and the National League, respectively. Ortiz (.301, 17 HR, 49 RBI) and Fielder (.299, 21 HR, 69 RBI) each determined the other three participants on their teams and personally extended the invitations as part of a new Derby format featuring a team competition between the American League and National League. Representing the host National League along with Fielder, the 2009 Derby winner in St. Louis, will be his teammate, Brewers second baseman Rickie Weeks (.277, 15 HR, 34 RBI); St. Louis Cardinals outfielder Matt Holliday (.316, 10 HR, 40 RBI); and Los Angeles Dodgers outfielder Matt Kemp, who is tied for the National League lead with 22 home runs and has an N.L.-best .611 slugging percentage. Ortiz was the champion of the 2010 Derby in Anaheim and has 68 total home runs in four previous Derby appearances (2004-06, 2010), which is tied for second-most all-time behind Ken Griffey, Jr.'s 74 homers. Joining "Big Papi" will be his teammate, Red Sox first baseman Adrian Gonzalez, who holds the American League's top marks with a .348 batting average and 75 RBI, along with 16 homers; Toronto Blue Jays outfielder/third baseman Jose Bautista, the Major League leader with both 27 home runs and a .679 slugging percentage; and New York Yankees second baseman Robinson Cano (.294, 14 HR, 54 RBI). In addition to being Ortiz's fifth career Derby, this will mark the third for both Fielder (2007, 2009) and Holliday (2007, 2010); the second for Gonzalez (2009); and the first for Bautista, Cano, Kemp and Weeks.
