Rangers starting pitcher Yu Darvish will make his major league debut against Ichiro Suzuki and the Mariners on April 9 at Rangers Ballpark. The Rangers announced the order of their rotation Thursday and decided not to break up left-handed pitchers Derek Holland and Matt Harrison, which means those two will follow Colby Lewis with Darvish slotted in the No. 4 spot and Neftali Feliz rounding out the five-man rotation.
