OAKLAND — Jesús Luzardo pitched five scoreless innings in his first big league start Tuesday. He dazzled, as expected, with a high-90s fastball, sinker and 90 mph changeup. A’s pitching coach Scott Emerson loved the composure he saw . . .
And, despite a dominant and compelling effort, Luzardo still has room to improve, particularly with his breaking ball. Tuesday, when Luzardo seemed to bounced a few when he wanted to throw a strike, and threw them for a strike when he probably wanted to bounce a few.
