Aaron Nola and the Rich Hill Prescription
One of the most interesting aspects of the Rich Hill story was his decision to break from convention and make his curveball – one of the game’s most effective pitches – his primary offering, a decision about which I wrote earlier this week.
That decision was one of a number of factors that has led to Hill’s late-career resurgence. As you’re probably aware, Hill led all major-league pitchers in curveball usage (49.7%) last season, throwing it more often than his fastball (47.2%). By this standard, Hill is an outlier. Conventional wisdom in baseball stipulates that the fastball should be the primary pitch for just about every arm. Rejecting that wisdom allowed Hill to become one of the most productive per-inning pitchers last season — and to receive a three-year, $48-million contract this offseason despite a limited track record of success.
The only regret Hill might have is that he didn’t change things earlier. What would Hill wish he had told a younger version of himself?
It’s that question which brings me to talented young Phillies starting pitcher Aaron Nola. Nola isn’t left-handed like Hill. His curveball doesn’t have quite the same shape. It is, perhaps, the next best thing to Hill’s curveball among major-league starters, however, depending upon how you judge performance and aesthetic beauty. It’s certainly part of a small group and a candidate in the discussion.
The curve tracks so well horizontally it made Jose Bautista flinch:
