I find it interesting how much more often Dillon Gee is discussed within the context of future Mets rotations than Jeremy Hefner is. I get that Gee was drafted and developed by the Mets, while Hefner was a scrap heap pickup.
A couple of things do separate them, though. Gee missed half a season last year with a shoulder issue, previously missed time with a different shoulder injury in the minors, and is pitching through another injury at the moment. There’s no such history for Hefner.
Moreover, Hefner has an edge in velocity, and that edge is only getting bigger. Hefner just had his best month, velocity-wise, of his career, his average fastball topping 92 miles per hour. Gee, meanwhile, just cracked 90 in June, and overall is around two MPH slower than Hefner across the board.
This is not to suggest that there’s a ton of room between the two. Both are probably backend filler in a rotation. And having both of them, under team control for a while, is important, given the need for quantity of pitching as much as quality.
But I’m not clear on why Gee’s future would be brighter than Hefner’s. Hefner has been as good as Gee so far, and seems like the slightly better bet to me going forward.
