Wei-Yin Chen had a rough day in Sunday's loss to the Angels, allowing five runs on five hits, three walks and three home runs in just four innings. Chen struck out five in falling to 7-5. It was a disappointing end to an otherwise excellent first half for the 26-year-old rookie, who enters the All-Star break the owner of a 3.93 ERA, 1.27 WHIP and 78/33 K/BB ratio through 104 innings.
