Rockies trade RHP Aaron Harang to Mariners

Mariners general manager Jack Zduriencik first looked into acquiring pitcher Aaron Harang last winter and finally landed him Thursday from the Colorado Rockies for minor league right-hander Steven Hensley and cash.

Harang immediately gives Seattle some experience and depth on a pitching staff that's been beaten up early in the season, especially the back end of the rotation. Rookie starter Brandon Maurer didn't make it out of the first inning Tuesday night and Blake Beavan has allowed five earned runs in both of his starts.

The Rockies acquired Harang last Saturday when they traded catcher Ramon Hernandez to the Los Angeles Dodgers. The right-hander went 10-10 with a 3.61 ERA last season for the Dodgers, but was left out of a crowded rotation this year.

Harang, who turns 35 next month, is 105-104 with a 4.19 ERA in 11 major league seasons with Oakland, Cincinnati, San Diego and Los Angeles.

Colorado never intended to keep Harang, and the Mariners needed another starter after allowing Jon Garland to opt out of his contract this spring rather than adding him to their roster. The Rockies scooped up Garland and put him in their rotation.

Harang is expected to join the Mariners on Friday, although his exact role is still to be determined. Seattle manager Eric Wedge said Harang will throw a bullpen on Friday and then the team will assess where he best fits. Harang told Zduriencik that he threw a simulated game at San Diego State on Wednesday and the Mariners are approaching the situation as though they have six starters right now.

Zduriencik also confirmed the Mariners will get some salary relief. Harang signed a $12 million, two-year deal with the Dodgers before the start of the 2012 season.

''Until he does his bullpen, and we have starters, the fact that he is going to bump somebody is a little premature right now. But he is a starting pitcher,'' Zduriencik said. ''If he is in good shape, and his pitch count is where it needs to be and his bullpen is successful, then we'll address it after that.''

The decision to go after Harang was partly due to a triceps strain sustained by Erasmo Ramirez, who is currently on the Triple-A disabled list. If Ramirez was healthy, or Jeremy Bonderman was ready to make the jump from Triple-A in his comeback attempt, Zduriencik said the trade may not have happened.

''We're in a position where we think this is something we should do because more than anything else it's tough to find starting pitching,'' Zduriencik said. ''And to have a guy available like this, that's this experienced, was the right thing to do.''

Hensley was a fourth-round draft choice by the Mariners in 2008 out of Elon University. He has a 30-30 record in 123 career minor league appearances, including two at Triple-A Tacoma this season.
