Hours after he struggled through another start, the Baltimore Orioles sent right-handed pitcher Jake Arrieta to the minor leagues early Friday morning. Arrieta, who lasted 3 2/3 innings Thursday night in a loss to the Los Angeles Angels, was optioned to Class AAA Norfolk. An off-and-on starter since being selected as the Orioles' opening day starter, Arrieta has compiled a 3-9 record with a 6.13 ERA. He allowed six earned runs on five hits Thursday night. "As far as getting another start, I really don't know," Arrieta told the Baltimore Sun before he was demoted. "I would like to say yes, but with the struggles and with the way the first half was, you know, who knows? I mean, am I confident that things are going to turn around and be more positive in the second half? Yeah, absolutely. There's no question about that, but right now the first half ended on a bad note. But I can't worry about it too much." The Orioles have yet to announce a corresponding move.
