Nicasio threw just one changeup in 2019, so I wouldn’t expect this pitch to all of a sudden become a major part of his repertoire.
Nicasio’s fastball hit the zone 60.5% of the time, but allowed a 19.0% HR/FB rate and a .300 BAA.
Nicasio’s slider found the zone 35.4% of the time, but saw its O-Swing rate drop 10% to 31.5%. Consequently, its K% fell to its lowest rate of the last five years.
As his primary pitch, Nicasio also took a step back with his four-seamer. The pitch dropped in average velocity by over one mph. However, he allowed almost 50% fly balls but had a surprisingly high .408 BABIP alongside it. Both of these may see a decline in 2019.
Nicasio’s slider has seen better days. He was able to get batters chasing at over a 40% clip however, they still found a way to get their bat on the ball. A .391 BABIP may have made him a bit unlucky but he will need to get more whiffs to be more comfortable with his slider.
Nicasio’s two-seamer was not an effective pitch. He let up way too much contact both in and out of the zone. A good chunk of batted balls were line drives resulting in a .370 average and a .455 wOBA against. This pitch may not be worthwhile.
Nicasio barely used his changeup in 2018. He did get batters swinging and missing out of the zone on the few occasions he did though.
