Ruben Tejada exits game after being hit in the head with a pitch

Mets shortstop Ruben Tejada left Wednesday afternoon's game against the Seattle Mariners in the first inning after being hit in the head with a Taijuan Walker fastball. 

Tejada remained on the ground for less than a minute before walking off under his own power. He was replaced by first baseman Eric Campbell, who took Tejada's spot at shortstop despite having played only one inning there in his major-league career. He made two appearances at shortstop this season for Triple-A Las Vegas. 

Tejada was hit in the hand with a pitch Tuesday night, but stayed in the game. He is batting .236 this season, with a .357 on-base percentage. 

The Mets won the game 3-2 as Bartolo Colon carried a perfect game into the seventh inning.
