First baseman Bryce Harper was removed by the Philadelphia Phillies in the bottom of the first inning of their 9-3 win over the Colorado Rockies on Saturday night with what the team said was a migraine.
Harper, who has played in all 40 games this season, participated in fielding practice and played the top of the first. He fielded a grounder off the bat of Mickey Moniak for a putout.
In the lineup as the Phillies' No. 3 batter, Harper was removed for pinch-hitter Felix Reyes, who took his place at first.
Harper was back in the lineup at first base and batting third for Sunday's game.
Without Harper on Saturday, Alec Bohm took center stage, homering twice and adding a double in Philadelphia's win. Trea Turner had four hits for the Phillies, who improved to 9-3 under interim manager Don Mattingly.
Harper is batting .282 with nine homers, 23 RBIs and a .929 OPS.
