Orioles manager Buck Showalter said either T.J. McFarland or Jake Arrieta will start on Thursday in Toronto. The O's decided to send down Jair Jurrjens in order to activate Miguel Gonzalez, so they'll need a fifth starter until Wei-Yin Chen (oblique) is ready. Arrieta is more stretched out since he's been used as a starter this season, but Showalter thinks McFarland would be able to throw 75-90 pitches. Neither pitcher would be worth streaming against the Blue Jays.
