Agreeing with DHonks above... To be labeled the "ace" of a staff, you simply must be the dominant starter of the staff. This more often than not means you are facing another team's ace. What the article did not provide was the amount of runs Ben allowed per category of run support. Case in point: Marlins Mets - Willis vs P. Martinez last night. 2-1. Both aces. Is Ben as talented as Dontrelle, Pedro, Felix, Randy? I don't believe so with a B fastball, A curveball and otherwise empty toolbox. I've always thought of starting opening day with our #5 starter, in order to give Ben a better shot every time out: #5 vs #1 #1 vs #2 #2 vs #3 etc.
