CapnZippers: Seth Lugo’s curveball averaged 3300 RPM last night. That spin rate is almost 10% higher than the next guy. Holy Moly! Mets maybe found a gem?

I made a note to do some digging. To be honest, I don’t have a lot to add. As has been measured, Seth Lugo has thrown an outstanding curveball, in terms of its spin rate. It’s outstanding not because it’s amazing; it’s outstanding because it stands out. The average spin rate is way higher than anyone else’s. As a different way to demonstrate that, I pulled up all the individual games with the highest-spin curveballs, from Baseball Savant. Lugo, in the majors, has appeared in 10 games in which he’s thrown at least one curve. A leaderboard:
Lugo dominates the spin charts in the way that Aroldis Chapman dominates the velocity charts. This isn’t a one-off fluke — Lugo has an exceptional breaking ball. The question is whether Lugo himself will become a quality pitcher, but this should at least get you to raise your eyebrows.
It’s really too soon to say how much this means. It’s not an easy thing to analyze an individual pitch, and Lugo won’t go anywhere if his other pitches don’t play well, too. Everything works together. There is some evidence that high spin is correlated to reduced slugging. And there’s evidence that high spin is correlated to increased whiffing. The evidence isn’t strong, but it makes sense intuitively, and again, this is all complex. It’s fair to say that Lugo’s curveball is interesting, without going any further. I don’t know how interesting this should make Lugo as a player, but I know that now I’ll keep my eye on him. I didn’t have any reason to think about him before.
By velocity and movement, the best comparison for Lugo’s curve in the PITCHf/x era is Brett Myers‘ curve. Myers threw a phenomenal curve for an entire decade. Garrett Richards has another comparable curve, but he’s never thrown it much. Jake Arrieta’s curve also compares well, so that’s promising. Lugo’s curve appears to be a major-league pitch. A major-league out pitch, even. We’ll see about the other pitches.
Lugo picked up his first-ever big-league strikeout on a curve. It’s with a clip of that curve that I’ll leave you today.
How interesting an arm is Seth Lugo? I don’t know. “More” would be one answer.
Jeff made Lookout Landing a thing, but he does not still write there about the Mariners. He does write here, sometimes about the Mariners, but usually not.
