Mark David Canha (born February 15, 1989) is an American professional baseball first baseman and left fielder for the Oakland Athletics.
Canha attended Bellarmine College Preparatory in San Jose, California, and the University of California, Berkeley, where he played college baseball for the California Golden Bears baseball team. The Florida Marlins selected him in the seventh round of the 2010 MLB draft. In 2014, Canha played for the New Orleans Zephyrs of the Class AAA Pacific Coast League (PCL).
The Colorado Rockies chose him in the 2014 Rule 5 draft from the Marlins, and then traded him to the Athletics for Austin House. During spring training in 2015, Canha led the Athletics in home runs. Due to the team's need for a power hitter following the offseason trades of Josh Donaldson and Brandon Moss, Canha made the Athletics' Opening Day roster. In his major league debut, on April 8, Canha had three hits and four runs batted in (RBIs). Canha remained with the Athletics throughout the 2015 season, and led all American League rookies in RBIs. He finished the season with 16 home runs and 70 runs batted in, while playing multiple positions for the A’s.
Canha underwent season-ending hip surgery after only 16 games with Oakland in 2016. Returning in 2017, he played 6 games with the A's before being optioned to the Nashville Sounds of the PCL on April 15. On April 8, 2018 the Athletics recalled Canha from the Sounds and he is currently their starting center fielder.
