Ohman, now in his eighth big-league season, gives the Marlins a veteran presence in the bullpen. In 51 appearances for the Orioles this season, Ohman has a 3.30 ERA in 30 innings. Lefties are batting .226 against him. Of particular interest to the Marlins: against Ohman, Washington's Adam Dunn is 3 for 18 while Philadelphia's Ryan Howard is 4 for 18 with a home run.
Marlins president of baseball operations Larry Beinfest said the deal was completed within the final hour of the 4 p.m. deadline.
"We wanted to add a second lefty to go with (Taylor Tankersley) out in the pen," Beinfest said. "Ohman fit the bill. Experienced, and he's been real tough on lefties, and he's battle-tested. Really, since we did the trade with (Jorge Cantu) on Thursday, we've only had discussions about trying to add to the team, specifically to the bullpen. We have some ground to make up, but we believe in them."
The Marlins have been interested in Ohman for several years. They will pick up the remainder of his salary for this season, or about $475,000.
"He's aggressive, he's experienced," Beinfest said. "He's been in this division before with the Braves and we thought it was a good fit. As far as Vandy goes, still a lot of potential there. Great kid. We really didn't see an opportunity for him in the near future, so hopefully this will be a good fit for him moving forward."
Beinfest said he is hopeful that Ohman can join the team in San Diego in time for Sunday's afternoon game. The Orioles are playing in Kansas City.
Over his career, Ohman is 11-9 with a 4.44 ERA. In 261 career innings, he has struck out 255 and walked 132.
VandenHurk has been up and down with the Marlins. He was 8-4 with a 4.68 ERA at Triple A New Orleans this season.
"It takes a depth a little bit," Beinfest said of starting pitching within the organization. "Obviously we have (Sean) West, who is ready to go. Andrew Miller has really improved in Double A. (Alex) Sanabia is here. We have Elih Villanueva. So there's still is some depth."
