RHP Chris Tillman: The rotation as a whole needs to improve in 2016, but the O's projected Opening Day starter is one of the biggest factors. Tillman, who pitched to a 4.99 ERA in '15, has to prove he can be a top-of-the-rotation guy for Baltimore again.
RHP Miguel Gonzalez: The typically consistent Gonzalez had a down 2015, marred by injury and underperformance. Gonzalez went 9-12 with a 4.91 ERA in 26 starts last year, but he is expected to be a full go in camp.
