Tampa Bay Rays: Fifth Starter
Mark Topkin of the St. Petersburg Times explains that manager Joe Maddon thought "the uncertainty may have weighed on [Davis]," which may explain his 10.24 ERA this spring.
Davis certainly has the pedigree to pitch in the majors -- he's the 15th-best prospect in the majors, according to our own Keith Law:
"In a perfect world, he's a borderline No. 1 starter because of the velocity and potential for multiple out pitches, with a strong likelihood that he'll settle in just below that and soak up substantial innings with above-average performance."
