Carlos Ramirez

On the strength of an incredible scoreless streak, Ramirez shot from Double-A to the majors in 2017. The right-hander did not allow a run last season until Sept. 20 -- he had perfect 0.00 ERAs with both New Hampshire (18 appearances) and Buffalo (seven appearances) and did not allow a run in his first seven big-league outings. His scoreless streak eventually ended at 47.2 frames. Relying on his slider as his primary pitch, Ramirez struck out 24.1 percent of the batters he faced at the major-league level while walking 5.2 percent. He's a flyball pitcher (55.0 percent flyball rate last season) and that skew led to some home-run problems despite just a 27.5 percent hard-hit rate. Still, he seemed to make an impression on manager John Gibbons. Ramirez should break camp with a middle-innings role with an opportunity for advancement into the later innings by the end of the year.
