Ellis, 34, batted .248 with seven home runs, 41 RBI and a career high-tying 14 stolen bases in 132 combined games with Oakland and Colorado last season. After being acquired by Colorado on July 1, he finished the season by hitting .274 with six home runs and 25 RBI in 70 games as the Rockies' everyday second baseman.
Ellis led Major League second baseman with a .995 fielding percentage last season and has posted the top fielding percentage at the position three times in the last six years after also doing so in 2006 and 2008. The 2011 season marked Ellis' seventh consecutive season with a .990 or better fielding percentage and his .991 career fielding percentage as a second baseman is the second-best all-time (min. 750 games) behind only Placido Polanco's .993 mark. In 2006, Ellis posted a .997 fielding percentage, which was then a Major League record for a second baseman, and followed it up by setting an Athletics franchise record for second baseman with a 102-game errorless streak from May 14-Sept. 10, 2007.
The 10-year Major League veteran owns a .266 career batting average in 1,126 games with Oakland (2002-11) and Colorado (2011) and his 90 career home runs as a second baseman (92 total career homers) rank ninth among active Major Leaguers. Ellis is Oakland's all-time home run leader as a second baseman with 84 roundtrippers and overall ranks eighth on Oakland's all-time doubles list with 204 in 1,056 games with the A's.
Ellis has twice led Oakland in batting average, hitting a career-high .316 in 2005 and .291 in 2010, and established career bests in 2007 with 161 hits, 33 doubles, 19 homers and 76 RBI in 150 games.
The South Dakota native has been active off the field throughout his career and was honored as the 2007 recipient of the Dave Stewart Community Service Award, which is given annually to an Athletics player for outstanding work in the community. Ellis is also a two-time winner of Oakland's Catfish Hunter Award, which is presented annually to the Athletics player whose play on the field and conduct in the clubhouse best exemplifies the courageous, competitive and inspirational spirit demonstrated by the late Hall of Fame pitcher. The award is voted upon by Oakland A's players, coaches and staff.
Ellis was originally selected by Kansas City in the ninth round of the 1999 First-Year Player Draft out of the University of Florida and traded to Oakland in 2001 as a part of a three-team, seven-player deal. He resides in Scottsdale, AZ with his wife, Sarah, and three children, Adelaide, Briggs and Dylan.
