With Tyson Ross, who was four outs shy of a no-hitter against the Diamondbacks last Friday, on the mount, the San Diego Padres had hoped that he would limit the Rockies and give their batters a chance to get fired up. Neither happened Wednesday.

Ross was never at his best at Coors Field — he’s 0-6 at the park — and Wednesday was no different. He allowed four runs, six hits, two walks and struck out seven in four innings in the 5-2 loss to Colorado. That was by no means disastrous at the hitter-friendly ballpark but it was the third inning that gave Ross the most problem. After walking the first two hitters of the frame, David Dahl was next at-bat and lined a two-run triple. He would score off a Trevor Story’s sacrifice fly for a 4-0 early lead.

“Pitches were at a premium for him today,” Padres manager Andy Green said. “Obviously after four that was enough. I think he did enough to keep us in the ballgame. We just didn’t do anything offensively.”

After a 13-run onslaught Monday, the Padres had insisted their batters were getting back on track. Tuesday and Wednesday’s games proved them wrong.

Righty Jon Gray ended his slump by striking out 11 Friars, walking one and allowing three in six innings. Before Wednesday’s start, Gray was 0-3 with a 10.34 ERA in his last three starts — the worse slump of his young career.

“We had our pitches to hit off Jon Gray early in counts, and we missed them,” Green said.

The Padres were also without two of their heavy hitters, Eric Hosmer, who was out for a family emergency, and Christian Villanueva, who was out because of a tight left hamstring. Both are expected back Friday when the Padres start a three-game homestand against the New York Mets.
