Conley looks bigger than he is on the hill, which can help an otherwise unspectacular changeup. Batters hit .411 off the pitch in 2019, a sign that Conley’s typically hard changeup isn’t getting its heavy sink with enough regularity.
The power fastball butters Conley’s bread. Lefties did a decent job of knocking around Conley’s heater in 2019, but glove-side fade gives the pitch a slightly higher ceiling than the average 95.5 mph four-seamer.
Conley’s long, loping slider was his most effective pitch in 2019. He’s varied its speed over the years, put it’s the vertical action that make Conley’s slider what it is.
Conley transitioned from starter to bullpen arm in 2018, resulting in a massive spike in his fastball velocity from 89.5 to 95.2 mph. The increased velocity resulted in a significantly improved pVal score to 2.7, while the pitch also experienced improvements in batting average and slugging against.
The changeup was Conley’s bread-and-butter pitch last season, holding hitters to a sparkling .175 batting average and .316 slugging percentage. This was backed up by a filthy 50.4% O-swing and 27.8% swing%, indicating hitters were completely off balance against the pitch.
Conley didn’t throw his slider much last year, but it sure was nice when he did. Holding batters to an average of just .115, the pitch resulted in an impressive 44% K rate. The lefty has never thrown the pitch more than 19% of the time in any season, but it was just as effective as any other offering in his arsenal in 2018.
