I took a look at Aaron Sanchez's batted ball stats this morning expecting to see a bunch of soft contact that would help explain the big difference between his ERA and xFIP. Most of it is luck, because nobody is going to make a 5.15 xFIP work, but I expected a lot of soft contact that would explain the difference at least in part. Among 334 qualified pitchers (25+ batted ball events), he:
- has the 79th-highest average exit velocity (90.2)
- he's 118th highest in exit velocity on FB/LD (93.9) and 89th highest on ground balls (87.3)
- he has the 67th-highest percentage of batted balls being hit at 95+ (43.2%)
- he's 201st-highest in barrels/batted ball event (this isn't bad)
Posting because I was legit surprised at how mediocre the contact profile is given the difference between his ERA and xFIP. People are hitting the ball harder off him than they do against most of the league.
He's not really doing anything that you'd like to see a starting pitcher do right now, aside from an above-average GB rate (which does limit the barrels against to a slightly better than average rate):
- his K-rate is below average
- he has the second-highest walk rate in the league among qualified starters
- when hitters make contact, they hit the ball harder than they do against most pitchers
I wonder how he'd do in a role where's only asked to go a max of 3-4 innings. I have no idea if this is true or not, but he seems to fare quite well early in starts and then fall apart by inning 5 or 6.
