Yoenis Cespedes debuted with the Athletics on Saturday afternoon, delivering a solo home run and an RBI single. The young Cuban outfielder didn't take a single swing as he drew a walk off Cincinnati's Johnny Cueto in his first at-bat. "This is the day we were waiting for," manager Bob Melvin said. "There was a pretty bright spotlight on him today, so for him to be able to go up there and take a walk his first at-bat, I think impressed me as much as the other at-bats. "Certainly, they got better and better as they went along: a bullet up the middle and then with two strikes fouled off some pitches and then finally got one he could handle and hit it out," Melvin said. "So, I would think he's going to go home tonight with a smile on his face, feeling pretty good about his first day."
