Mathis is the second right-handed pitcher reeled in this week by Cleveland, which obtained Joe Martinez in a trade with the Pirates on Tuesday. Both pitchers have starting experience, but were brought into the fold with a better chance at competing for jobs in the Tribe's bullpen.
Last season, Mathis split the year between the American League champion Rangers and Triple-A Oklahoma City. In 13 appearances at the Major League level, Mathis went 1-1 with a 6.04 ERA between two stints.
Excluding a forgettable outing on May 14 in Toronto, where Mathis was charged with eight earned runs over just 1 1/3 innings, the righty had a 3.00 ERA out of the Rangers' bullpen. His second stint with Texas in July consisted of four scoreless innings.
While with Oklahoma City, Mathis went 5-7 with a 5.66 ERA over 18 games, including 15 starts. Across 89 innings, the 27-year-old righty allowed 116 hits, piling up 54 strikeouts against 31 walks. Mathis also pitched for Esta in the Dominican Winter League, posting a 3.29 ERA in seven games.
Mathis has pitched in the big leagues with Texas in each of the past three seasons, going 3-3 with a 4.84 ERA in 45 career games (six starts). His best showing with the Rangers came in 2009, when he fashioned a 2.14 ERA over 22 relief appearances.
