CINCINNATI -- The Pittsburgh Pirates made another move to upgrade their bullpen on Thursday night, acquiring right-hander Joakim Soria from the Detroit Tigers for a minor leaguer.
Soria, 31, was 3-1 with 23 saves and a 2.85 ERA in 43 appearances with Detroit this season. He didn't allow a run in 13 of his last 14 appearances.
The deal was made a few hours after the Pirates got versatile reliever Joe Blanton from Kansas City for cash.
Soria will move into a setup role behind closer Mark Melancon in a bullpen that already ranks among the league's best. Pittsburgh's 2.71 bullpen ERA ranked second to St. Louis for the NL lead.
"We feel it will just lengthen and deepen our bullpen," general manager Neal Huntington said.
Pittsburgh gave up infielder JaCoby Jones, a 23-year-old who was recently promoted to Double-A. The Pirates will have to make a move to create a roster spot when Soria joins the team, which opened a four-game series in Cincinnati on Thursday.
Before the game, manager Clint Hurdle noted that the back end of the bullpen has been solid with Jared Hughes, Tony Watson and Melancon, who has converted a club-record 30 consecutive saves.
Kansas City reached the World Series last season with a deep bullpen that took a lot of the pressure off the starters. Hurdle said teams want to try to do the same.
"People are going to emulate success," he said. "The game seems to have gone in that trend."
Pittsburgh, which lost 15-5 to the Cincinnati Reds on Thursday, is second by 5 1/2 games in the NL Central to St. Louis, which defeated the Colorado Rockies 9-8. The Pirates lead the NL wild-card race.
Pittsburgh is missing Jordy Mercer, on the 15-day DL with a sprained left knee, and Josh Harrison, who is recovering from surgery on his left thumb. Both are expected back to help the Pirates' push for the playoffs.
Detroit also dealt All-Star left-hander David Price to Toronto earlier Thursday in a deal that had taken most of general manager Dave Dombrowski's attention. He said the Pirates expressed an interest on Wednesday.
"This is one we went back-and-forth on today with a couple of clubs," Dombrowski said. "It pretty much came together today. (Pittsburgh) is going for it to try to win, which is understandable."
