OAKLAND -- Ryan Cook's 2013 debut went rather awry, much like his performance in the Cactus League, where he finished with a 6.14 ERA. But the A's reliever is confident his next outing will look much different.
"I was just mechanically off," said Cook, who walked three and hit a batter in two-thirds of an inning in Tuesday's 7-1 A's loss to Seattle. "I knew what I was doing, and I couldn't make the adjustment. That's what made me more upset. I was just flying open with my front side, nothing staying closed, and I couldn't get anything glove side."
When Cook walked in a run, it snapped his 15-inning scoreless streak dating back to last season, which isn't even the longest of his young career. The right-hander started 2012 with a 23-inning scoreless streak en route to garnering an All-Star nod.
Cook was, at times, the A's best reliever last year, and he and lefty Sean Doolittle will be relied upon to set up for closer Grant Balfour this season.
"It felt really good to get back in there, even though the results didn't pan out the way I wanted," he said. "That just makes me want to get back out right away. I think I was just a little overamped, trying to do too much and make perfect pitches instead of just pitching how I pitch."
