 Biographical Information
He made his major league debut for Texas on August 13, 2014, in his fifth season in the Rangers' organization. he had moved around a lot during that time, as Texas was already his fourth stop of 2014, and he had also pitched for more than one team in both 2011 and 2013. he was used mainly as a reliever during his minor league apprenticeship, although he did start a total of 13 games out of 114 games, most of those starts coming in 2014 before the call to the Show. He was 6-3 with an excellent 1.66 ERA in 27 games when he arrived in the Lone Star State.
Claudio set a couple of club marks when he made his debut as a reliever in the 8th inning of a 10-1 blowout loss to the Tampa Bay Rays: he was the 56th different pitcher used by the team that year, and the 34th pitcher. He pitched a perfect inning after arriving late at the ballpark, having only been called up after Yu Darvish was placed on the disabled list earlier that day, and he was expected to be sent down after the game to make way fore the next day's starter, Robbie Ross. After his one inning of work, catcher J.P. Arencibia succeeded him on the mound to pitch the 9th in mop-up duty, upping the total number of pitchers used that year to 36 with 6 weeks still left to play.
