Hitter: The Pirates were hitless through six innings until Gregory Polanco's infield single in the seventh.
Of note: Edinson Volquez got knocked around in his first start against the Orioles in Sarasota, Fla., in a split-squad start. He gave up 7 hits, 6 earned runs and 2 home runs in 22/3 innings. He struck out three and didn't walk a batter.
News of the day
Starter Charlie Morton surrendered his first home run of the spring and gave up five hits for the first time, but got eight groundouts.
"When I was ahead of hitters, everything turned out OK. Problem was I didn't get ahead of many hitters," Morton said.
Morton gave up two first-inning singles, but escaped the inning unscathed. Boston scored two unearned runs in the second before Mike Carp blasted a home run to right field on a 2-2 pitch to make it 3-0 in the third.
"I was working him in, in his first at-bat. Just stayed in, just stayed in. I threw one, he just sat on it," Morton said. "And I missed. The ball didn't really do anything. He got a good swing on it."
Morton said he threw two split changeups in the outing and added he will work on getting ahead in the count by throwing first-pitch strikes.
He threw 8 of 15 first-pitch strikes Sunday.
"There's room for improvement there," manager Clint Hurdle said. "The thing that Charlie did that we hadn't seen him do in the past? He's made a commitment to using that two-seamer inside, run it back. He threw it in there 10 times, with intent, with purpose, with conviction.
"The rhythm might not have been as good. ... He made one pitch he'd like back."
Relievers Jason Grilli, Mark Melancon, Tony Watson and Zack Thornton each threw scoreless innings.
