Missions' Wisler goes six scoreless

Even Matt Wisler's mistakes worked out for him Friday night.

The one hit he allowed was a triple that he said could have been a home run.

"That was a mistake pitch. I missed, but I got away with it a lit bit," Wisler said of Teodoro Martinez's three-bagger in the third. "I don't think he squared up great on it, even though it got to the wall."

The Padres' No. 5 prospect struck out six and walked three over six scoreless innings, pitching Double-A San Antonio to a 3-1 victory at Frisco.

Wisler (6-4) opened the game with back-to-back 1-2-3 frames innings and retired the leadoff man in the third before Martinez tripled to center field.

"My fastball location definitely helped. I was able to keep it down in the zone," Wisler said. "I mixed in my slider or changeup a little bit, but early in the game it was a lot of ground balls off my fastball down in the zone."

With Martinez on third and one out, Wisler went with what had worked to that point and got a grounder off the bat of Guilder Rodriguez. Second baseman Cory Spangenberg -- San Diego's 14th-ranked prospect -- fielded the dribbler and fired to catcher and No. 2 prospect Austin Hedges, who tagged Martinez out.

"That was big. That was a good defensive play," Wisler said. "And getting the next guy on one pitch to end the inning was huge, too."

Beginning with Rodriguez, the 2011 seventh-round pick set down nine in a row.

"I was feeling great there. It was just working really well," Wisler said. "I was getting ahead in counts, and that was mostly just location. I never made too many mistakes. Up to the sixth, I was feeling pretty confident."

With one out in the sixth, the 20-year-old right-hander issued the first of his three walks.

"It got a little messy," he said. "They were all lefties and I was missing outside with my two-seamer.

"I don't think it was really fatigue. I hadn't thrown that many pitches, I hadn't had to work too hard up to then. I hadn't thrown out of the stretch very much, though, and I think I was mechanically a little off. Those two-seamers ran off the plate."

With two down and the bases loaded on free passes, Wisler ended his night by fanning Joe Benson.

"I was definitely glad to have that, to not give up a run with two outs," he said. "It was pretty big to get that strikeout."

Wisler lowered his ERA to 3.18, which would rank sixth in the Texas League if he had enough innings to qualify.

Spangenberg had two hits and scored a run for San Antonio. Reymond Fuentes, who's ranked three spots behind Spangenberg, singled in a run and contributed his 29th stolen base.

Rougned Odor, the Rangers' No. 5 prospect, singled and walked for the RoughRiders and has reached base five times in his first two Double-A games.
