Jones and Ryan Flaherty each delivered solo shots in the bottom of the fifth off Pirates reliever Arquimedes Caminero to give the Orioles the lead, 4-2.
But Pirates outfielder Elvis Escobar's triple off Brad Brach in the top of the seventh inning tied the game at 4.
Pirates righty Radhames Liz, who has not appeared in the Majors since he was with Baltimore in 2009, went two innings in his first spring start. Liz allowed a run on two hits and a walk in his fourth Grapefruit League appearance.
"I'm different," Liz said of what has changed in the past six years. "My mental approach is different. Those days, I didn't know what I was doing, [I] was just throwing as hard as I could. Now I'm mentally strong, just trying to make the pitches I need to get the hitter out. It's real exciting to be back. [Pirates manager Clint] Hurdle said they're going to give me innings, maybe use me in long relief. I'm OK with that -- it's still baseball."
Orioles starter Chris Tillman went four innings and held Pittsburgh to one run -- on Elias Diaz's sacrifice fly in the second -- in a solid spring outing.
"I thought it was really good actually," Tillman said of the 65-pitch outing. "Fastball command was really good, changeup got better as the game went. Cutter was really good, curveball got better as the game went, so I think that was good, both out of the windup and the stretch."
Tillman has allowed just one run total over two Grapefruit League starts. He also threw three innings against Puerto Rico in another exhibition game last Saturday.
Up Next: Brian Matusz will make his second start this spring for the Orioles on Friday at 1:05 p.m. ET against the Red Sox at Jet Blue Stadium. Orioles starters Kevin Gausman and Wei-Yin Chen will be pitching in separate Minor League games back in Sarasota. Boston will send Justin Masterson to the hill opposite Matusz.
