Can Paxton solidify a spot for 2014?

James Paxton was impressive in his major league debut against Tampa Bay on Saturday (6 IP, 1 ER, 3 K), becoming only the third Seattle pitcher to go at least six innings and allow one earned run or less in their first game in the bigs. In his next start against St. Louis on Saturday, the Mariners' young lefty has a chance to further stake his claim to a spot in the back of the rotation in 2014.
