Taiwanese left-hander Wei-Yin Chen, who struggled in his intrasquad game outing Saturday, said he’s still getting adjusted to different mounds than the ones he has been used to pitching on in Japan.

“I feel like it’s a little bit flat over there (in Japan), so I’m still making an adjustment,” Chen said through interpreter Tim Lin. “It feels fine to me, but I’m trying to fit in and get adjusted to it.”

Chen faced five batters and threw 31 pitches before the inning was ended because of a pitch count, allowing two hits, one walk with one strikeout.

Orioles manager Buck Showalter said the conditions, which included a wind blowing out to left might have contributed to Chen's struggles.

"I think some of the challenge Chen had yesterday, if you keep in mind that most of their games are played inside, I don’t know if he ever pitched in those conditions," Showalter said.

Chen said he concentrated mostly on the movement on his fastball Saturday, and wasn’t concerned about his breaking ball and change-up.  

“Definitely I felt really excited to be on the mound,” Chen said. “This was the first real game that I pitched on the mound since I’ve been to the states. I felt a little bit nervous but it’s really fun pitching here.”
