The curveball is by far Fiers’ best pitch and is his primary breaking ball. The curve induced more swings outside the zone in 2019, which netted a 3% jump in SwStr%. Fiers continues to get weak contact and whiffs from this pitch, and he would benefit from increasing its usage in 2020.

Fiers’ fastball is his primary option for called strikes. It’s consistently thrown between 90-91 mph, but is moderately effective due to the number of offspeed and breaking pitches Fiers offers. Fiers should decrease the fastball’s usage, as his luck with the pitch may just run out in 2020.

The cutter is not utilized all that often, and has similar movement to his slider at a slightly higher velocity. Fiers could improve the effectiveness of this pitch if he was more consistent with his release points between the fastball and cutter.

Fiers’ splitter saw a drop in SwStr% for the fourth straight season in 2019. Fiers throws it in the zone over 50% of the time and has allowed Z-Contact 92.1% of the time. Fiers should lower the zone rate on the splitter or he could see inflated numbers against it in 2020.

Unlike the curveball, the slider is a hard sweeping one, and is Fiers’ secondary breaking pitch. It induces swings and misses at a well below-average clip for a slider.

Fiers’ primary pitch may have been his best last season. He is a fly-ball pitcher yet this pitch was his most successful at keeping the ball in the yard. He also gained a bit more control walking much less than the season before.

Another commonly used offspeed pitch of Fiers, his changeup is another liability with the long ball. He is able to keep the ball on the ground 50% of the time, yet when it is hit in the air, expect a home run.

Not a great pitch, Fiers gives up way to many extra-base hits with his cutter. It dropped in velocity last in season and has still remained a liability.

One of his many offspeed pitches, Fiers’ curveball is his strikeout pitch. With a 40% strikeout rate, Fiers was able to reliably throw it to get outs. Additionally, if it was put in play it was usually on the ground.

Fiers’ two-seamer does its job by generating ground balls. However, batters lay off it out of the zone too easily and make a ton of contact regardless of location.
