Jones went deep in back-to-back innings, hitting a solo shot in the fourth off Cardinals starter John Lackey and a three-run blast in the fifth off Mitch Harris. Jones entered the game with just one spring homer and three RBIs.
Orioles starter Bud Norris went four innings and allowed three runs (two earned) on three hits and four walks. The pair of earned runs came from Matt Adam's two-run homer on a 3-0 pitch in the third inning.
"I wanted to see a little bit better results today," said Norris, who has pitched to a 9.26 spring ERA in 11 2/3 innings. "I was kinda upset with myself, 3-2 walk and 3-0 fastball that [Adams] hit over the fence. I'm not necessarily happy with that. But [pitching coach Dave Wallace] came out shortly thereafter and said, 'You look fine mechanically, the competitive nature is going to come.' That's what we were talking about on the bench.
"Obviously getting home and pitching in front of the fans in Baltimore is going to be great, but it's a big league game for a reason. I'm going to get there. I'm not that worried. I just want to get there."
Lackey, making his second of four Grapefruit League starts, was charged with five runs on seven hits, including two homers, with Baltimore's Manny Machado going deep in the first inning. Lackey threw three perfect innings in his first spring start but wasn't concerned with the different results Sunday.
"I felt pretty good, for the most part. I thought it was a pretty good work day," Lackey said. "I threw a lot of fastballs, cut it, sank it, threw some four-seamers. Overall, pretty good."
Rule 5 Draft pick Jason Garcia, pitching for the first time since March 10, struck out three in a scoreless seventh for Baltimore.
Up next: After their only off day this spring on Monday, Ubaldo Jimenez will start in Bradenton against the Pirates on Tuesday afternoon. Radhames Liz will take the mound for Pittsburgh.
