Who is he and where did he come from?
He’s Tyler Uberstine, and if you’ve been furrowing your brow at Greg Weissert coming in and letting another inherited runner score, he’s a guy you might want to get to know.
Uberstine, from Santa Monica, California, was selected by the Red Sox in the 19th round of the 2021 MLB Draft out of Northwestern and worked his way up the Major League system after initially stalling in single-A ball for three years. But a switch flipped following his Tommy John surgery and he consistently struck out more than a batter per inning his whole way up the ladder.
The Easter bunny had a surprise in store for Uberstine yesterday, as the 26-year-old came in to pitch the sixth inning and made his Major League debut, keeping it a 6-4 ball game against the Padres. He showcased his notable command and got his first Major League strikeout… and his second one, too! This gave the Red Sox the ability to tie the game up in the seventh.
Uberstine was surprisingly thrown back in to start the eighth and gave up his first Major League home run. That put him in a position to take the decision loss in his debut, but the managerial blunder shouldn’t take away what was a pretty good appearance: 2 2/3 innings pitched, 1 run, two strikeouts, three hits, and a walk.
What position does he play?
He’s a right-handed pitcher. He’s primarily been used as a starter since he was drafted, but he can provide multi-inning relief in the situation the Red Sox find themselves in currently, especially with Johan Oviedo, who very much was penciled into that role, going to the IL, and Garrett Whitlock’s wife giving birth to their second child. (Congrats to the Whitlock family!)
Is he any good?
He could be. Uberstine turns 27 on June 1, and so it’s cool to have a homegrown talent this side of 30 that really climbed his way to the Major League roster despite not never blowing anyone away. Now, he did have a health stumble by way of a Tommy John surgery in 2023, requiring him to miss most of that season, but his fastball remains at around 94 miles per hour. Unfortunately, he lacks a bit of command with the heater, which grades out at just 45 on the scouting scale. He also has a five-pitch arsenal, and his sinker tops 90. He’s best known for painting the top of the strike zone, as displayed in the second pitch in this video. His dependability since returning from Tommy John surgery and ability to adjust to batters quickly has likely led to his early-season debut above some other arms in the organization.
Tl;dr, just give me the stats.
Last year, in Double-A and Triple-A, he made 25 appearances, logging 137 strikeouts in 120 innings with a 3.58 ERA, while giving up 16 homers and walking 37 batters.
Show me a cool highlight.
When he has command, he really has it. Here’s another strikeout.
What’s he doing in his picture up there?
Practicing the ridiculous on-base celebration the Red Sox are doing this year, or at least the toned-down version, which our own Maura McGurk is totally right to criticize. I don’t long for others to get on turbulent plane rides, but it was a much better celebration following that trip to Denver.
What’s his role on the 2026 Red Sox?
You’re seeing it right now. He might eat some innings, and he’ll likely induce a lot of swings and misses. Last year, his whiff percentage was 38% in Triple-A. It’s notable that Uberstine was put into a game in which the Red Sox found themselves down by two runs, because getting them through those somewhat-trivial innings may be his primary job at first. It’s also totally likely that, if his impact is just menial, Payton Tolle’s time to rejoin the club in mid-May to buy the team another year of contr…. I mean, to help his development, may signal the end of Uberstine’s time on this squad, barring any sort of injury or horrendous play by any current member of the bullpen. But the best case scenario is that this draft pick carves out his own spot on the roster the same way he’s entered conversations to make his Major League debut in the first place.
