William Bradford Myers (born December 10, 1990) is an American former professional baseball outfielder and first baseman. He played in Major League Baseball (MLB) for the Tampa Bay Rays, San Diego Padres, and Cincinnati Reds.

Originally drafted by the Kansas City Royals, he was traded to the Rays in 2012. He won the AL Rookie of the Year Award in 2013.

Myers attended and played baseball at Wesleyan Christian Academy in High Point, North Carolina. As a freshman, Myers had a .450 batting average and was an all-state third baseman. During his junior year, he went 10–0 as a pitcher. After committing to the University of South Carolina, Myers was drafted by the Kansas City Royals. In 2008, his team won a state championship.

Myers was drafted by the Kansas City Royals as a catcher in the third round, with the 91st overall selection, of the 2009 Major League Baseball draft. Myers signed a contract with the Royals, that included a $2 million signing bonus, in August 2009. Before the draft, Myers had committed to South Carolina during his junior year.

Myers made his debut in professional baseball in 2009, when he played catcher and batted .369 with five home runs in 84 at bats with Royals' Rookie League affiliates, the Idaho Falls Chukars and the Burlington Royals. Myers began the 2010 season playing catcher for the Burlington Bees of the Midwest League and was named to the Midwest League All Star team. On July 1, 2010, the Royals promoted Myers to the Wilmington Blue Rocks of the Carolina League, a league generally considered more advanced than those in which he had previously played. Myers played catcher and finished the 2010 season batting .315 with a .429 on-base percentage overall, and totaled 14 home runs, 83 runs batted in, and 85 walks between his time in the Midwest League and Carolina League. In 2011, playing for the Double–A Northwest Arkansas Naturals, he batted .254 with eight home runs and 49 RBIs in 99 games. He played primarily outfield in 2012, and was named to appear in the 2012 All-Star Futures Game.

On December 9, 2012, Myers was traded to the Tampa Bay Rays (along with Jake Odorizzi, Patrick Leonard, and Mike Montgomery) in exchange for James Shields, Wade Davis, and a player to be named later (later chosen to be Elliot Johnson). He started the 2013 season with the Triple-A Durham Bulls of the International League. On June 17, Myers was called up to the Rays, for whom he played outfield.

Myers won the AL Rookie of the Year award in 2013, beating teammate and pitcher Chris Archer and Detroit shortstop José Iglesias. In spite of the fact he had not joined the Rays until their 70th game on June 18, Myers led AL rookies with a 53 RBIs in the 88 games he did play in. The last player to lead AL rookies in RBIs in fewer than 90 games was Hoot Evers playing for the Detroit Tigers in 1946, when he had 33 in 81 games, and also became the first-ever hitter to win the award in under 100 games.

In the post-season, Myers had two singles in 20 at bats.
