Greg Mahle relieved Newcomb in the eighth and gave up a two-out triple to Erisbel Arruebarrena. However, Mahle stranded the Drillers' runner at third and eventually earned the win after the Travelers scored a run in the bottom of the frame.
Urias was nearly as good as Newcomb, allowing four hits while fanning three batters in six scoreless innings. He did not earn a decision and has not dropped a start since Aug. 1. The 19-year-old right-hander began his year with Tulsa before undergoing eye surgery in May.
His recovery kept him out until early July, when he made two short appearances for the Arizona League Dodgers and then one for Class A Advanced Rancho Cucamonga. Urias returned to Tulsa on July 26, and has yet to give up more than three earned runs in a start since.
Newcomb, Arkansas' 6-foot-5 southpaw, is 2-0 with a 1.29 ERA and leads all Minor Leaguers with 158 strikeouts on the year.
