[SI] What Went Wrong with the Diamondbacks’ Pitching? - The hard-hit rate in the heart of the zone against the D-backs ranked 30th with a worst in MLB rate of 51.9%. The 10.4% Barrel rate ranked 26th. But when compared to pitches not in the heart of the zone, their ranks improved to 24th on hard-hit and 16th on Barrel. The conclusion here is simply that the D-backs' pitchers did not have good enough stuff to get away with pitches in the middle of the zone. When they did so, they got hit harder than almost any team in the league.
