The rotation is set. Orioles manager Buck Showalter has chosen Jake Arrieta as his No. 4 starter, allowing the right-hander to pitch the home opener for the third consecutive season. Arrieta will take the mound on April 5 against the Minnesota Twins at Camden Yards after Jason Hammel, Wei-Yin Chen and Miguel Gonzalez start the three games against the Tampa Bay Rays at Tropicana Field.
