[1] Originally an infielder, he began his professional career with the Arizona League Rangers and hit .301 in 29 games.

"[3][4] The suspension continued into the following season[1] and when he returned he was assigned to the Spokane Indians of the short-season Northwest League, where he hit .258 in 67 games.

[2] He spent the next two seasons with the Hickory Crawdads of the South Atlantic League, hitting only .229 in 250 games with 18 homers and 103 RBI.

[2] Because of his poor hitting stats and perceived arm strength the Rangers chose to convert him to a pitcher prior to the 2011 season.

It was revealed that he had torn the ulnar collateral ligament in his right elbow and had to undergo Tommy John surgery, which cause him to miss the 2013 season.

[6] West was designated for assignment by the Rangers on January 5, 2015,[7] and claimed by the Toronto Blue Jays nine days later.

[2] West was traded to the Los Angeles Dodgers in exchange for cash considerations on May 4, 2015 and assigned to the Double–A Tulsa Drillers.
