It goes without saying that the Twins’ bullpen is in need of some juice. They have seemingly found a few strong building blocks, including Yoendrys Gomez, who has been a revelation for this team after the Twins pulled him out of thin air. Others have done enough to keep the team afloat, but the bullpen as a whole ranks 24th in ERA and 29th in strikeout rate. The team desperately needs to add velo and stuff. Thankfully, there are two young prospects right across the river who look like they could solve some of the bullpen problems down the stretch.
RHP Marco Raya
Currently sitting at #17 on MLB Pipeline’s Twins prospect rankings, Marco Raya’s hype has worn off over the past couple years after struggling to adjust to the upper levels of the minor leagues. However, Raya’s stuff is as good as ever this year, and he has begun to find more success with the Saints in May.
Although his fastball is averaging 96 MPH this season, deadzone tendencies and inconsistent command have led to poor results. Instead, Raya has been relying on two excellent breaking balls in the mid 80s. With more than 12 inches of horizontal break and spin rates around 2,800 RPM, his sweeper has generated a 44% whiff rate this season. Raya pairs it with a curveball that sits at a similar velocity, but has more of a 12-6 shape. He also mixes in a power changeup in the low 90s that has been a weapon against lefties, but his struggle to command the pitch has forced him to limit its usage.
After posting a 9.98 ERA in his first 11 appearances with 11 walks and 15 strikeouts, Raya has since hit his stride, working a 4.02 ERA and 1 walk to 17 strikeouts in his last 8 outings. He has the highest graded stuff on the Saints and is currently holding a 40 man spot, so a major league debut could be on the horizon.
RHP Alejandro Hidalgo
It has been a rocky road of a minor league career for Alejandro Hidalgo. Signed out of Venezuela, he spent the first two years of his pro career in the Angels’ system before being shipped to Minnesota for Gio Urshela ahead of the 2023 season. His time in the Twins’ system did not get off to a good start. At 20 years old, Hidalgo ran a 5.24 ERA as a starter in High-A Cedar Rapids before a shoulder injury costed him the entire 2024 season. He returned in 2025 with much improved stuff, playing at both High-A and Double-A. This season, he has moved to the bullpen and taken his stuff to a whole new level at age 23, showing flashes of absolute dominance in the upper minors as he is now just across the river from Target Field.
Hidalgo leads with a dangerous fastball at 95-97, and at 18 iVB from a lower release point, the heater possesses elite carry. He has a cutter in the upper 80s that may be his best whiff pitch and also has a reliable changeup in the mid 80s that he uses to attack lefties. An occasional sinker is mixed in, but it’s mainly a three pitch arsenal, all of which are undoubtably big league pitches if he can command them.
This projection is more of a work-in-progress, as Hidalgo currently sits at a 6.75 ERA this season. Home runs and walks have both been major issues, but the stuff is some of the best in the system and cannot be ignored. He has struck out 43 batters in 28 innings of work while walking 14 this season.
Both Raya and Hidalgo have their flaws, but they also have electric stuff that can only be matched by a few other pitchers in the organization. There are a lot of questions to be answered over the next few months as the Twins hope to get David Festa and Garrett Acton back from injury. Will Kendry Rojas settle into a more traditional bullpen role? Will Kody Funderburk recapture his dominance from the end of the 2025 season? There are lots of pieces to fit into this puzzle, and these two flamethrowing prospects in the Saints’ bullpen have a chance to make a big impact.
