Rangers pitcher Matt Harrison is set to join the team's rotation and will start on Sunday when the team travels to Seattle for the final game of its series with the Mariners, according to a report Wednesday afternoon from Aaron Gleeman of NBC Sports. 

Harrison has been shut down since Feb. 20 when he started experiencing back stiffness that was later confirmed through an MRI. The return on Sunday will be the first time he'll pitch in a big league game in more than a year after undergoing multiple back surgeries and dealing with Thoracic Outlet Syndrome.

He made only two starts last season before going down with the lingering back issues, but was an All-Star in 2012 when he pitched 213 innings with a 3.29 ERA. He finished that season 18-11 with 32 starts. 

The 28-year-old lasted eight innings in a shutout during his minor-league rehab last Saturday. He struck out five and walked one, allowing three hits on the day.

The Rangers are currently 13-8 and second behind the Oakland Athletics in the AL West. SI WIRE: Brewers’ Johnny Hellweg diagnosed with torn UCL in right elbow
