Rojas, who came to the Twins as an outfielder Alan Roden in the trade that sends a reliever Louis Varland to Toronto, is a 22-year-old southpaw (23 next week) who climbed three minor league levels in 2025, culminating in his first taste of Triple-A work. The Cuban-born southpaw breezed through High-A and Double-A before running into trouble in his first 32 1/3 innings at the highest minor league level. He scored 26 runs (7.34 ERA) in that time and walked his opponents 14.7%.
Those struggles occurred in a small sample size of nine Triple-A appearances at a time when most of the opponents he faced were much older and further along in their development. However, walks haven’t been a big problem for Rojas so far in his pro career, and most scouting reports predict he will eventually have average command with the potential for three average or better pitches. Rojas could be in line to make his MLB debut next summer, so there was no chance the Twins would leave him unprotected.
Prielipp, 24, was a second-round pick in 2022 and could have been a first-round pick had he not come off Tommy John surgery at the time of the draft. Elbow issues have continued to plague the Alabama product since being drafted. He underwent an internal brace procedure in 2023 and had logged all 30 professional innings by the start of the 2025 season.
However, Prielipp looked healthy this past season, playing in 24 games (23 of which were starts) and missing a lot of bats with an above-average groundball percentage. He posted a 3.65 ERA, 27% strikeout rate and 7% walk rate in 61 2/3 Double-A frames before showing some fatigue late in the season with a 5.14 ERA in five Triple-A games (four starts). He has already been ranked in the top 100 at FanGraphs and ESPN, and he will likely receive even more attention on such lists in the offseason. As with Rojas, there was no doubt that he would be added to the 40-man squad today.
Morris, 24, doesn’t have the same ceiling as Rojas and Prielipp, but might be the most MLB-ready of the bunch. He started 19 games (plus two extended relief appearances) in Triple-A this season and worked to a 4.09 ERA with a 22.4% strikeout rate and a 7% walk rate. The 2022 fourth-rounder averaged 95.5 mph on his four-seater in Triple-A last season — an increase of 1.6 mph from the previous year — and has drawn praise for his plus command and a five-pitch arsenal that includes at least average numbers for his heater, slider and cutter.
Klein, a Twin Cities native, was an undrafted free agent who signed with his hometown club in 2022. He threw 106 1/3 innings between Double-A and Triple-A, good for a combined ERA of 3.98. Klein, who turns 24 in April, fanned 27.6% of his opponents for a walk rate of 8%. He sits 94-96 mph with his sinker and four-sieve, and complements those fastballs with a cutter, curveball and changeup.
Gonzalez came to the Twins from the Mariners as part of the 2023 Jorge Polanco trade. He was a top-100 player at the time who struggled in his first season with the organization, but returned to the tune of a .329/.395/.513 batting line this season as a 21-year-old between Double-A and Triple-A. He could get an MLB look in 2026.
Mendez was one of the team’s many deadline pickups and came over in the trade that sent Harrison Bader to Philadelphia. He hit a combined .299/.399/.439 with more walks than strikeouts (13.6% to 13.2%) in 491 innings at the plate between High-A and Double-A. He is a bat-first, hit-over-power outfield prospect who is widely considered one of the top 20 in a deep Minnesota farm system.
Francys Romero from BeisbolFR.com first reported that Rojas had been selected.
