BALTIMORE — Left-hander Mark Hendrickson agreed Tuesday to a one-year contract with the Orioles that guarantees him $1.4 million after pitching well out of Baltimore’s bullpen last season.

The 35-year-old Hendrickson went 6-5 with a 4.37 ERA in 53 games with Baltimore last year. He was most effective in relief, going 4-0 with a 3.44 ERA.

He will receive $1.2 million this year, and the contract includes a club option for 2011 for $1.2 million with a $200,000 buyout.

Hendrickson joined the Orioles last season after pitching for Toronto, Florida, Tampa Bay and the Los Angeles Dodgers. He is 56-68 with a 5.00 ERA in 268 career games.

Baltimore also agreed to a minor league contract with left-hander Will Ohman, who was invited to big league spring training camp. The 32-year-old was 1-0 with a save and a 5.84 ERA in 21 games with the Dodgers during an injury-shortened 2009 season.

To make room on the 40-man roster for Hendrickson, the Orioles designated right-hander Armando Gabino for assignment.

According to a report on MLB.com, the Orioles appear to have most of the bullpen in place.

Michael Gonzalez will close and Jim Johnson will work in a set-up role. Koji Uehara will have an unspecified role, while Cla Meredith and Hendrickson are likely to be in the mix, leaving two possible spots on the Opening Day roster.

Ohman could serve as the left-hand reliever in specific situations. Ohman will likely compete with Alberto Castillo, leaving a few right-handers to fight for the final job.

Kam Mickolio, Dennis Sarfate and Matt Albers should be among that group. Starters David Hernandez and Jason Berken may also state their cases for a bullpen job.
