Rangers sign possible new closer

Texas has now added two arms over the last few days

The Rangers added an arm to their bullpen on Tuesday, agreeing to a deal with free-agent reliever Seung Hwan Oh, a source told's Jon Paul Morosi, confirming a previous report by MLB Network insider Ken Rosenthal.

The deal is pending a physical, per Rosenthal. The club has not confirmed the report. According to Morosi, the deal is for one year, $2.75 million with a $250,000 buyout and a $4.5 million club option for a second year. There are also performance bonuses up to $1 million for each year.

Oh, who pitched for the Cardinals in 2016 and '17, is entering his third season in the Major Leagues after 11 seasons in Korea and Japan. He'll be looking to bounce back after a rocky '17.

The 35-year-old had an impressive debut season with St. Louis two years ago and ended up taking over as the team's closer, but he struggled in 2017 and was eventually moved out of the role.

Oh recorded 20 saves last season, but he also had a 4.10 ERA in his 62 relief appearances and saw his strikeout rate decline, with 54 K's in 59 1/3 innings. In his lights-out 2016, Oh had 19 saves and a 1.92 ERA in 76 outings, with 103 strikeouts in 79 2/3 innings. | David Adler
