He was selected in the 5th round of the 2001 MLB Draft by the St. Louis Cardinals. Schumaker spent the remainder of 2001 with the short-season New Jersey Cardinals, and in he had 158 hits for the Potomac Cannons. His minor-league career advanced from Single-A in, when he was promoted to the Tennessee Smokies, where he spent two full seasons. A.316 batting average in was enough to give him a shot with the Cardinals during spring training in.
St. Louis Cardinals
After spending the first two months of the season in Memphis, Schumaker made his major-league debut on June 8 against the Boston Red Sox at Busch Stadium. Schumaker entered the game as a pinch-hitter for the pitcher, Chris Carpenter, and was struck out by David Wells. Schumaker remained with the club until June 14, failing to pick up a hit in five at bats. On August 10, he was called back up to the Cardinals and picked up his first major-league hit two days later in a pinch-hit appearance against the Chicago Cubs.

Schumaker hit his first Major League home run on April 5, 2006, in a game against the Philadelphia Phillies. He played in 28 regular-season games in 2006 for St. Louis, but did not appear in the postseason. He would still receive his first career championship ring as the Cardinals bested the Detroit Tigers in 5 games of the 2006 World Series. Schumaker became a capable leadoff hitter and a strong defensive outfielder with an above-average arm. However, he has difficulty against left-handers; from 2007 to 2009, he had a.210 batting average, a.278 on-base percentage, and a.226 slugging percentage against them. He had six hits in seven at bats against the New York Mets on July 26, the first Cardinal to do so since Terry Moore against the Boston Braves on September 5, 1935. Combined, Schumaker and his teammate, Albert Pujols, were the first pair of Cardinals to hit five or more hits each since Charlie Gelbert and Taylor Douthit against the Chicago Cubs on May 16, 1930. On February 9, 2009, Cardinal 2nd basemanAdam Kennedy was released by the club, which sparked discussion about placing Schumaker as the regular second baseman in 2009. Schumaker, who played shortstop in high school and college began working out with Cardinals third base coachJose Oquendo in spring training to prepare. Schumaker would go on to become the Cardinals' starting second baseman during the 2009 season. On February 8, 2010, Schumaker signed a two-year deal with the Cardinals worth $4.7 million, buying out his final arbitration years. On August 9, 2010, Schumaker hit his first major leaguegrand slam against the Cincinnati Reds. On August 23, 2011, he made his major league pitching debut when he came in as a reliever in the top of the 9th. He faced 5 batters, striking out 2, walking 1, and giving up a 2 run home run to Aaron Miles. After a great performance in the NLDS against the Philadelphia Phillies in which he drove in Rafael Furcal for the only run in the Cardinals' 1-0 victory in Game 5, Schumaker was left off the National League Championship Series roster due to an oblique injury. He was added back to the 25-man roster for the 2011 World Series against the Texas Rangers and won his second championship title after the Cardinals won the series after a deciding 7 games. Schumaker signed another 2-year deal with the Cardinals on December 12, 2011, for $3 million.
