Ranking the Twins Top-5 Slider Prospects

As pitchers move through a farm system, the organization hopes to use technology and data to help them improve their pitching repertoire. On the 20-80 scouting scale, nearly all of the sliders below have room to grow this season, which can be dangerous for opposing batters. 

5. Ronny Henriquez, RHP
Current Slider/Future Slider: 50/55
Don't let Henriquez's small stature deceive you. He is a legitimate starting pitching prospect. He joined the Twins organization from Texas as part of the Mitch Garver trade. Last season, he spent time at High- and Double-A, where he posted a 4.71 ERA with a 1.10 WHIP and 105 strikeouts in 93 2/3 innings. At both levels, he was more than two years younger than the average age of the competition. Henriquez is already on the 40-man roster, so there is a good chance he will make his debut in 2022. 

4. Jordan Balazovic, RHP
Current Slider/Future Slider: 50/55
Balazovic has come a long way since he was a lanky Canadian high school pitcher in the 2016 draft. His velocity has increased throughout his professional career, leading to an increased walk rate as he adjusts to his ever-changing repertoire. His slider is one of three pitches with a future grade of 55 or higher. He uses a delivery that makes it tough to pick up the ball, which makes his offspeed offerings even more dangerous. A back injury kept him from debuting until later in the 2021 season. Otherwise, he may have joined Bailey Ober and Joe Ryan at the big-league level. 

3. Francis Peguero, RHP
Current Slider/Future Slider: 55/55
Peguero was the prospect included in the Sonny Gray trade with the Reds. Last season, he pitched in relief at High-A, where he had a 4.96 ERA and a 1.22 WHIP in 32 2/3 innings. His fastball velocity increased from the low-90s to the upper-90s last season. This increase in velocity projects to help his secondary pitches to play better as he moves closer to the big leagues. Even with the better fastball, his strikeout numbers dropped last season, so he will be a player to watch this season. He is 24-years-old, but he will fit into the team's upper-level bullpen pitcher over the next couple of years. 

2. Sean Mooney, RHP
Current Slider/Future Slider: 55/60
Mooney may be an unfamiliar name to some Twins fans, but his slider is still one of the system's best. Minnesota selected Mooney in the 12th round back in 2019 from St. John's. He injured his elbow during his collegiate career and had Tommy John surgery. Since returning to the mound, he utilizes a low-slot arm angle that helps him to have a great slider and an above-average changeup. Last season was his professional debut, and he posted a 3.64 ERA and a 1.07 WHIP in 13 appearances. Over 42 innings, he struck out 71 batters, so a healthy Mooney looks like he can be a pitching weapon. 

1. Matt Canterino, RHP
Current Slider/Future Slider: 55/60
There's a reason Canterino is considered one of the organization's top pitching prospects. His fastball ranks near the top of the farm system, and his top-ranked slider adds even more to his arsenal. He has a four-pitch mix that can make him a dominant starting pitcher, but there have been health concerns throughout his professional career. Minnesota is confident in him bouncing back this season and proving he can stay in a starting role. However, his fastball-slider combination is enough to make him a dominant reliever if the team needs to make future adjustments.
