Justin Masterson will start Cleveland's opener against Toronto on April 5. "He earned it by being the guy we wanted to see out there every five days," Manny Acta said. "By being the guy that whenever you rolled into another town, the other team was wondering if they were going to see him or not. That's what being a No.1 means in this league." Acta chose Masterson over Ubaldo Jimenez, the team's presumed ace who came over in a five-player trade at the July 31 deadline from Colorado.
