Bruce Chen allowed one earned run over three innings Tuesday in the Royals' 8-2 defeat of the A's. Chen issued no walks and struck out two. He has agreed to remain in Royals camp all spring rather than pitch for Panama or China in the WBC, and will hope to claim the final spot in the Kansas City rotation. Chen posted a 5.07 ERA, 1.37 WHIP and 140/47 K/BB ratio across 191 2/3 innings last year.
