DETROIT The Detroit Tigers have stocked up on many of the top pitching prospects in baseball the last several years, and heading into this season, theres a similar logjam at the MLB level. So should the Tigers make room for Michael Fulmer? Theres no question he looked like a budding ace in his rookie season, posting a 3.06 ERA, 3.76 FIP and earning AL Rookie of the Year honors. His second season wasnt quite as strong, but Fulmer was still a 3.5 WAR pitcher over 25 starts. Do the Tigers really need to see another partial season of Zimmermann?
