Christopher Brandon Young (born September 5, 1983) is an American former professional baseball outfielder. He played in Major League Baseball (MLB) for the Arizona Diamondbacks, Oakland Athletics, New York Mets, New York Yankees, Boston Red Sox, and Los Angeles Angels.

In 2007, he became the first rookie in Major League history to hit 30 home runs and steal 25 bases. While primarily a center fielder earlier in his career, Young later transitioned to a fourth outfielder role.

Young was born to Carolyn and Robert Young in Houston, Texas. When Young was in high school, his father was a mechanic and his mother was a real estate agent. Young began his baseball career at St. Thomas More elementary/middle school and later attended national powerhouse Bellaire High School. In 1999, the school went 38-2 and won the Texas high school baseball championship over Duncanville High School by mercy rule. Young received All-State honors his senior year, but shattered the ulna and radius bones in his left arm in the state playoffs while attempting to catch a fly ball hit by Elkins High School's Chad Huffman.

The Chicago White Sox selected Young in the 16th round of the 2001 MLB Draft. The broken arm suffered in his senior year caused his draft stock to fall but he signed for $130,000, more typical of a fifth round draft pick. In 2003, he was an Appalachian League All-Star outfielder. In 2005, he was a Baseball America 1st team Minor League All-Star outfielder and the Chicago White Sox Minor League Player of the Year.

After the 2005 season, the White Sox traded Young to the Arizona Diamondbacks with Orlando Hernández and Luis Vizcaíno for Javier Vázquez and cash. In 2006, he was a Triple-A All-Star outfielder and Baseball America 2nd team Minor League All-Star outfielder.^{[citation needed]}

Young made his major league debut on August 18, 2006, and began the 2007 season as the Diamondbacks' everyday center fielder. On August 17, 2007, against the Atlanta Braves, he hit his 23rd home run of the year, setting a Diamondbacks rookie record. He also became the 8th rookie to hit 20 home runs and steal 20 bases.

For the season, his 27 stolen bases led all National League (NL) rookies (13th in the NL overall), and his 32 home runs were enough for 2nd among NL rookies (behind Ryan Braun, and tied for 10th overall). Among other accomplishments, Young finished 2nd among NL rookies in extra-base hits (64) and at bats (569), 3rd in runs (85) and 5th in runs batted in (68). He also hit .237 with a .295 on-base percentage, and led NL rookies by striking out 141 times. Besides, he hit nine leadoff home runs, to set an MLB rookie record.

Young was a unanimous selection for the 2007 Topps Major League Rookie All-Star Team as a result of the 49th annual Topps balloting of Major League managers. He finished fourth (10 points) in the vote for the 2007 NL Sporting News Rookie of the Year Award by 488 major league players and 30 managers, being only surpassed by Ryan Braun, Troy Tulowitzki and Hunter Pence, as well as in the 2007 Baseball America Rookie of the Year award and the Baseball Prospectus 2007 Internet Baseball NL Rookie of the Year Award competitions.
