First baseman Daric Barton and shortstop Cliff Pennington, who both exited Sunday's 8-3 loss to the Orioles with injuries, were back in the lineup for Oakland's first game against the visiting Yankees.
Barton, hit by a pitch above his right elbow by Baltimore starter Brian Matusz in the fourth inning on Sunday, chose to play on Tuesday despite healing from the contusion.
The infielder, who has started all 15 A's games this year, underwent X-rays on Sunday before having an MRI on Monday -- both of which came back negative.
Pennington, meanwhile, was the No. 9 hitter on Tuesday after exiting Sunday's game in the seventh inning. He underwent X-rays -- which came back negative -- near the area of his right hand and wrist after being stepped on while diving back to first base in the third inning.
Both Barton and Pennington were afforded the luxury of resting their respective injured bodies on Monday, as the team enjoyed its first off-day of the season.
