Dane Dunning, RHP, Texas Rangers

After being traded for a second time in his young career, this time from the White Sox to the Rangers in the 2020 offseason. He is finally ready to settle in and start producing for the Texas Rangers.

Dunning features a four-pitch mix of fastball, curveball, slider, and changeup. The fastball has a lot of late movement and has a heavy sink to so it is generally considered more of a sinker than a true fastball.  Many believe his curveball has taken over his slider as his best secondary pitch.

Dunning has always been an above-average pitcher even during his time in the minors, including his strikeout capability. During his three seasons at the University of Florida, he collected 174K in 163 IP. Furthermore, in his 2 years at low A and Double-A, he collected 300Ks in 266IP.

Now in 2021 in his first season with a rotation spot secured he is off to a hot start. He currently has an xERA of 2.55 which is good enough for the 83rd percentile. While also maintaining an xOBP of .211 which Is good enough for the 90th percentile.

Aside from his expected stats he has also has been able to attack hitters by throwing a first-pitch strike to 65.5% of batters faced. While also getting batters to chase at the rate of 47.7% out of zone swing%.

In his 3 starts in 2021 he has a 16Ks in 15IP and has only surrendered one earned run with a FIP of 2.29. While it is a small sample size so far, and there will be some regression. This is the type of performance I would expect from Dunning going forward.

Dean Kremer, RHP, Baltimore Orioles

Kremer is Baltimore’s seventh-ranked prospect and came over from the Dodgers in the Manny Machado deal of 2018. At that time Kremer led all minor leaguers in strikeouts with 178Ks in 131IP.

He continued his ways in 2019 in the high minors going 9-6 with a 3.72 ERA, 1.30 WHIP, and 122 Ks in 113 IP.

Kremer features a four-pitch mix of fastball, cutter, curveball, and changeup. While the fastball is the more often used pitch, it is not his best that belongs to his curveball.

He uses the curveball as both a chase pitch out of the zone as well as a pitch he can use to throw for strikes. He is able to generate a 28.6whiff% on his curveball with only a .181 xBA.

While he did receive a cup of coffee at the end of 2020. He was able to win a job in the rotation in spring training and is making the most of his time so far.

If you are just looking at the standard stats it may seem like Kremer is just another guy. However, if you look deeper there are a few things that stand out.

First off, he is still striking out more than one batter per nine (28K%). He is also limiting hitters barrel rate ( 6.7%), which ranks in the 58th percentile.

Kremer is still only 25 years old so he still has plenty of time to develop and work on adjusting to major league hitting. I project Kremer as a middle-of-the-rotation pitcher that will continue to strike out batters at a high rate.

Amed Rosario, SS/OF, Cleveland Indians

Amed was an international free agent in 2012 signed by the New York Mets, and he quickly climbed the prospect ranks and was ranked as high as 5th best in 2017 by MLB Pipeline.

While in the minor leagues he showcased his above-average defense and his speed. He swiped sixty bags in 452 games while reaching base at a 34% rate.

The speed and defense were enough for him to be promoted to the major league club in 2017 as a 21-year-old. In 2018 and 2019 he showcased why he was promoted when he combined for 24HR and 33SB in 1247 PA.  However, we saw the regression in 2020 when he only hit four HR and didn’t steal a base in 147PA.

Then in the 2020 offseason, New York shipped him off in the Fransisco Lindor deal. Now in Cleveland, Amed has split time between shortstop and centerfield. We have seen the regression from 2020 continue in 2021 as well. Currently, all his expected stats are in the bottom 20% of the league. xBA, xwOBA, xSLG, and Brl% are all in the 20th percentile or worst.

His one true outlier is his speed and that has been absent since 2019. His last stolen base was on September 24th of 2019 and he hasn’t even attempted a stolen base since August 29th of 2020.

I would be looking to sell Amed as quickly as possible before the regression continues and the sell now window closes forever.

“(Kremer) is also limiting the hard-hit rate (46.7%), which only ranks in the 26th percentile.” Afraid that’s backwards – he’s not limiting anything, the MLB average hard-hit rate is 35.1% and that percentile means 74 percent of pitchers are better at limiting hard hits than Kremer. His whole Statcast page is a sea of blue (except for strikeout percentage and barrel rate), unfortunately for those of us who have him.

Yes, you are correct I must have mis-read the statcast page. thanks for the head-up.
