Center fielder Jarrod Dyson was back in the lineup and batted in the leadoff on Friday against the Orioles. Dyson went 0-for-4 with four strikeouts on Tuesday against the Yankees and was held out of the lineup on Wednesday.
Yost said Dyson's absence on Wednesday was due to Yankees starter Andy Pettitte, a tough lefty who negates Dyson's speed by holding runners on.
Billy Butler had done well in 13 previous games at Camden Yards before Friday, posting a .345 batting average with two home runs and nine RBIs in 55 at-bats.
Yuniesky Betancourt made his first Minor League rehab start for Double-A Northwest Arkansas on Thursday and went 2-for-5 as the designated hitter. Betancourt is on the 15-day disabled list and has been out since May 3 with a high right ankle sprain.
