ARLINGTON (January 17, 2013) -- The Texas Rangers have finalized a $55 million, five-year contract with All-Star left-hander Matt Harrison.

The deal announced Thursday includes a 2018 club option that could become guaranteed depending on the number of innings Harrison pitches.

Harrison was 18-11 with a 3.29 ERA in 32 starts last year and is 32-20 over 399 innings during the past two seasons. He started Game 7 of the 2011 World Series, which the Rangers lost at St. Louis.

Texas acquired Harrison along with shortstop Elvis Andrus and right-hander Neftali Feliz from Atlanta in July 2007 in a seven-player deal that sent Mark Teixeira to the Braves.

Harrison has a career record of 48-30 with a 4.08 ERA in 126 games the past five years.

The deal came a day after the 27-year-old left-hander filed for salary arbitration. Harrison could have become a free agent following the 2014 season.
