Two mistakes ruined Wei-Yin Chen's chance of a third straight win since coming off the disabled list.
Chen yielded two home runs to Eric Hosmer, and the Kansas City Royals rallied for a 4-3 victory over the Baltimore Orioles on Wednesday night. Alcides Escobar doubled home the winning run with one out in the ninth inning.
Hosmer hit a solo homer on a full-count pitch in the first and his two-run homer in the eighth tied the score at 3 and finished Chen's night with a no-decision.
''He's definitely a really good hitter,'' Chen said through an interpreter. ''I don't think I made a mistake. I attacked the strike zone. He just swung the bat really well tonight.
''The 3-2 fastball was in a really good location. On the second home run, I think the location was OK, but I can do better.''
While Chen might not have thought Hosmer's home runs were on mistakes, Orioles manager Buck Showalter believed they were.
