News: Chen went two shutout innings in his Grapefruit League debut Thursday, allowing one hit and striking out one.
Impact: Chen, coming off a 16-win season in which he had a 2.76 ERA after the All-Star break, has had a quiet and healthy camp so far. The key to his second-half success last year was limiting long balls -- he allowed 17 home runs in 104 innings in the first half, but just six home runs in 81.2 innings the rest of the way. With Chris Tillman as the Opening Day starter, Chen slides in as the No. 2 starter.
