Despite dealing with his fair share of command and control issues throughout the year, Red Sox pitching prospect Isaac Stebens still turned in a solid 2024 season.

Stebens, who just turned 23 last month, was selected by the Red Sox in the 16th round of the 2023 draft out of Oklahoma State .

The Stillwater native received an at-slot $150,000 signing bonus that July but did not pitch for a minor-league affiliate after putting pen to paper.

He instead had to wait until last April to make his professional debut.

Stebens opened the 2024 campaign at Low-A Salem but was not there long.

The right-hander allowed just three runs (one earned) on seven hits, four walks, and 14 strikeouts in six relief appearances (11 innings) before receiving a promotion to High-A Greenville on April 25.

In 29 outings for Greenville, Stebens posted a 3.68 ERA (3.77 FIP) with 73 strikeouts to 31 walks over 51 1/3 innings of relief in which opposing hitters batted .228 against him.

That includes a 0.53 ERA (2.62 FIP) in his final 12 appearances (17 innings) of the season dating back to July 14.

Altogether, Stebens forged a 3.18 ERA (3.58 FIP) with 87 strikeouts to 35 walks in 35 total relief appearances (62 1/3 innings) between Salem and Greenville last year.

Among 39 Red Sox minor-leaguers who threw at least 60 innings, Stebens ranked third in strikeout rate (31.3 percent), fourth in strikeouts per nine innings (12.56), 11th in FIP, 12th in ERA, 14th in xFIP (3.79), and 17th in batting average against (.220).

On the opposite end of the spectrum, he ranked 33rd in walk rate (12.6 percent) and 34th in walks per nine innings (2.49), per FanGraphs.

Listed at 6-foot and 194 pounds, Stebens featured four pitches last season, per his SoxProspects.com scouting report .

Throwing from a low three-quarters arm slot, the righty sat between 92-94 mph and topped out at 95 mph with his fastball while also mixing in an 83-84 mph slider, a 78-80 mph curveball, and an 84-86 mph changeup.

As he recently explained to hosts Andrew Parker and Chris Henrique on Beyond The Monsters To the Show We Go podcast , Stebens implemented three new pitches into his arsenal last year after primarily relying on his fastball at Oklahoma State.

Because of that, the 2024 season served as somewhat of an adjustment period for him.

I wouldnt say it was seamless.

It was definitely a grind, Stebens said.

There was no backlash on my part.

I was all about it.

I knew it was what needed to be done.

But going from throwing one pitch thats pretty good to adding three more, it definitely increased my walk rate just because I didnt know how to control those yet.

So were still learning those.

Hopefully, having a long career, Im going to nail some of those things down.

I was able to strike out more in less innings than I did at OSU [in 2023], so a lot of good things, he continued.

But it was definitely a grind learning those new pitches, just utilizing them more than anything.

I had three of the four I have now going into the year but the usage rate went from 85 percent fastball and 10 percent slider and five percent changeup to about 40-20-20, so it was a big difference to split up that 80 percent.

Stebens is not currently regarded by publications such as Baseball America or MLB Pipeline as one of the top pitching prospects in Bostons farm system.

SoxProspects.com projects him to return to Greenville for the start of the upcoming season, though he made clear in his conversation with Parker and Henrique that he, at the very least, wants to make it to Double-A Portland before the end of 2025.
