Hiro Nakajima's first game as a big-league player was A-OK. Nothing spectacular, but no flubs, just a solid day. "I thought he looked good," A's manager Bob Melvin said of the A's shortstop. Nakajima went 0-for-2 with a walk, which came in his first plate appearance. He fielded two grounders cleanly, and turned a double play smoothly. Nakajima said through interpreter Hiroo Nishi that he knows big-league baserunners are more aggressive than those in Japan, so he is trying to observe them closely this spring. He got a good look when Taylor Green came hard into the bag in the second inning as Nakajima was taking a flip from Jemile Weeks; he made the throw to first and got out of the way quickly. "He's a smart guy and acclimates quickly," Melvin said. "He's feeling things out. Nothing panics him."
