He played in Major League Baseball (MLB) for the Milwaukee Brewers from 2004 through 2013, the Seattle Mariners in 2014 and the Pittsburgh Pirates in 2015.

[3] On the diamond, he played nearly every position, routinely in the middle infield and even pitching in relief for Coach Chris Decker.

[1] Hart's next appearance in the majors was Sunday, August 14, 2005, when he hit his first career MLB home run, a three-run blast against the Cincinnati Reds into the Upper Deck at Miller Park.

During spring training prior to the 2007 season, Hart, who stands at 6 ft 6 in (1.98 m), recorded the fastest 60 yard dash of any player on the Brewers roster.

[17] In July 2010, Hart was voted by his peers to not only play in the All-Star Game in Anaheim, but also was selected by MLB officials to participate in the Home Run Derby.

Along with Ryan Braun, Prince Fielder, Rickie Weeks, and Casey McGehee, the Brewers had one of the best top five slots in MLB.

Hart had another productive regular season with the Brewers in 2011, posting 26 home runs, and 63 RBIs with a .285 batting average, .386 OBP, and .866 OPS.

Hart's drop in home runs and RBIs is a result of missing the first month of the season with an injury, and being moved to bat first in the order in July, limiting the number of RBI chances he had.

A two-time All-Star, Hart spent nine of his 11 Major League seasons with the Brewers, batting .276 with 154 home runs, 508 RBI and 83 stolen bases in 945 games.

Among the 38 players who have collected at least 2,000 plate appearances in a Brewers uniform, his .491 slugging percentage ranks sixth all-time.

[24] Corey is the son of Johnnie and the late Donna Hart and has two sisters, Tabitha (older) and Ali (younger).
