Simmons doubled to left, plating La Stella and pinch-runner Philip Gosselin to tie the score at 4. Storen settled in after that, retiring Jordan Schafer and Jose Constanza on groundouts to end the inning.
"He was just a little pumped up," manager Matt Williams said. "The ball was up in the zone. He ended up calming down after he threw a few pitches and got the ball back down in the zone again."
Although the result was not ideal, Storen and Williams were both pleased with the outing. Facing hitters and getting comfortable during spring is part of the process, Storen said.
"You just tend to speed up because you get in a game and face some hitters and try to throw a little hard," Storen said. "I made the adjustment. That's the big thing. I'd probably be a little more frustrated if I didn't come back and find the zone."
Added Williams: "His velocity was good today. The first time out, he was all right."
