I’m virtually out of pitchers to write down about, I swear. We’re transferring on to the center relievers. The fellows who generally have to take it on the chin, who hardly ever get the credit score they deserve, however oftentimes make or break shut video games.
The Crimson Sox’ beginning rotation depth and high quality ought to assist maintain this group more energizing than they’ve been within the current previous. Proper now, I believe this group is likely to be on the sunshine aspect, however relievers spring up out of nowhere and can be found on the drop of a hat, so a commerce or the addition of a DFA’d arm from one other staff may add high quality to the bullpen. Right here’s a have a look at method too many pitchers who would possibly get an opportunity for the Crimson Sox this yr.
Justin Slaten’s 2025 was disappointing, largely as a result of he was unavailable for a lot of the center a part of the season. He posted a 4.24 ERA with an 18.2% strikeout fee and seven.3% stroll fee. These numbers had been a big step down from his rookie season, however the underlying stuff was simply nearly as good.
His fastball particularly was glorious. It has stable vertical motion and nice velocity with large extension. In 2025, the swinging strike fee was among the many finest within the league at 15.6%, whereas the best contact fee was an amazing 31.3%. His cutter was a dependable strike-getter and likewise restricted laborious contact. Slaten struggled to place lefties away in 2025 as a result of leaving his curveball within the zone with two strikes too often, however higher command ought to see the pitch return strikeouts. His sweeper was helpful in placing away righties and may proceed to be a weapon for him.
The problem for Slaten was getting out of bother. His left-on-base fee of 55% was remarkably low and may rise to a traditional fee over a full season. His 2024 fee was 71%, and there’s little purpose to imagine it shouldn’t normalize given his stuff. Aroldis Chapman and Garrett Whitlock are the highest canine within the Crimson Sox bullpen, however Slaten will probably be requested to deal with high-leverage conditions frequently.
Expensive Alex Cora, I do know navigating the center innings might be tough, significantly in a good sport. Hopefully, your rotation offers you six innings typically sufficient that no one within the pen must be overworked. I’m writing to you as we speak to plead that you simply don’t give the ball to Greg Weissert each night time. I do know it’s tempting, however don’t do it.
Every of the final two seasons, Weissert has been close to the highest of the league in appearances by way of June, after which seen his efficiency tail off in the summertime earlier than reemerging on the finish of the season. Weissert instructions his fastball on the prime of the zone, the place it performs properly as a result of its flat strategy angle. Towards righties, he makes use of a sinker and slider/sweeper to nice impact. Lefties are an issue, with nothing else moreover a fastball to get strikes with, although. He’s finest used matching up with righties in a one-inning spot, and shouldn’t be requested to do way more.
I don’t suppose I’ll ever be capable to stop Zack Kelly.
The stuff is simply too good to not work. His four-seam averages 96 mph with seven ft of extension. The pitch has a flat strategy angle, although I’m wondering if it’s a bit “lifeless zoney”, as a result of righties have been capable of deal with it. It was primarily a two-strike pitch and returned whiffs as a result of stable command, however the contact towards it was laborious. Early in counts, he used a sinker and a cutter that every earned strikes and restricted harm. His sweeper additionally punched out hitters, however just like the four-seam fastball was hit laborious. Lefties received four-seams and cutters for strikes, with changeups deeper in counts. The sluggish ball strike fee was an abysmal 49% to lefties, and must see enhancements to develop into a viable weapon.
Kelly’s strategy towards righties is sound, whereas he wants an “out-pitch” towards lefties. Regardless of this, his OPS allowed was .831 towards right-handed hitters and simply .604 towards lefties. I’ll chalk this as much as unhealthy luck. He struck out 29.3% of righties in comparison with 15.7% of lefties. His batting common on balls in play was over 0.400 towards righties and is certain to come back all the way down to a extra regular fee. His left on base proportion can also be positive to come back up, except there are some underlying points with the stretch that I’m not seeing. Should you’re out on Kelly, I don’t blame you. After wanting into the numbers, I’ll go the opposite method and predict that Kelly will probably be a key member of the Crimson Sox bullpen by the top of the season.
Ryan Watson was a Rule 5 draft decide, which provides him a stable probability to interrupt camp with the staff. He received’t be utilized in high-leverage spots, which implies his job is to throw strikes. If he can throw strikes and deal with low-leverage work, he’ll doubtlessly be utilized in extra significant spots later within the season. Within the minors, he used a fastball, sinker, slider, and curveball. His four-seam hasn’t missed bats within the minors, however his low-release and above-average extension ought to permit the pitch to play on the prime of the zone. His slider and curveball have every proven the power to create whiffs as properly. In his first spring coaching outing, he featured a low-90s cutter as properly that has potential. The stuff doesn’t soar off the web page, however he has weapons to assault either side of the plate and supply an inning or two of reduction at a time.
Of the non-roster invitees, Keller has the most effective probability to make the roster given the monetary dedication. He’s in line to make $1.8 million if he breaks camp with the staff. I don’t know a ton about Keller; he’s spent the final a number of seasons in Japan, most lately with the Yomiuri Giants. He has a fastball, cutter, curveball combine, with the four-seam making up the majority of his arsenal. It is available in at 151.7 kilometers per hour, which sounds fairly quick, however is definitely about 94 mph. His secondary pitches had been utilized in a small pattern, so far as I can inform, with middling outcomes. He additionally walked three males in his second spring coaching outing, which you’ll be able to’t afford to do as one of many lower-leverage arms within the bullpen. The Crimson Sox are prepared to pay him if he makes the roster, so there’s clearly one thing they like, although.
Tayron Guerrero wasn’t a reputation I knew till Christopher Smith wrote about his journey to Boston, however now I’m all in. He’s a 6-foot-8 righty with huge velocity and command points. He began taking part in baseball in 2007 after watching the Crimson Sox win the World Sequence, and was within the main leagues lower than 10 years later. He hasn’t been capable of follow an enormous league staff, bouncing round from group to group and spending time abroad, however his velocity offers him an opportunity to be particular if he can discover the zone. He’s utilizing a four-seam and a two-seam that every stand up to 100 mph, a splitter, and is engaged on a gyro-slider as a technique to be within the strike zone extra typically. He’s on a minor league deal and is unlikely to make the opening day roster, but when he proves the power to throw strikes, he may climb the bullpen belief tree and find yourself in high-leverage spots. Of the names on the backside of this record, Guerrero has the very best ceiling.
Did you want John Schreiber? If that’s the case, you’re gonna love Seth Martinez. Martinez spent final season with the Marlins, primarily in Triple-A. Earlier than that, he made 111 appearances for the Astros from 2021 to 2024, registering a 3.93 ERA over that point. He’s a side-armer with large extension who tops out about 90 mph, utilizing a sinker, cutter, four-seam, sweeper, and changeup. His fastball is tremendous flat, and in concept, ought to play on the prime of the zone, whereas his sinker can work to jam righties. His sweeper and changeup have every proven bat-missing potential previously, however his lack of velocity caps his ceiling and makes command paramount. He’s one other non-roster invitee with an out of doors shot to make the staff.

He exists! He’s thrown a number of single innings in reduction up to now this spring, and his slider seems to be sharp. His fastball has excessive vertical motion, and his changeup form is tremendous attention-grabbing. *Insert Rick Reilly-style joke evaluating the size of Noah Tune’s story to a Grateful Useless tune.* It’s most likely a protracted shot at this level, however I might be satisfied.
Aye! I’m relievin’ right here! Nittoli is a non-roster invitee with some main league expertise. He makes use of primarily a cutter that doesn’t truly minimize, from a low arm angle. It’s not one thing I’ve seen earlier than, which might be a basic case of survivorship bias, nevertheless it may additionally present a glance that hitters haven’t seen earlier than. He makes use of a sinker, changeup, and sweeper as properly. He’s sort of like Cooper Criswell, however extra Italian-sounding.
Having totally different seems to be out of the bullpen is essential. The Crimson Sox have an affinity for low-slot pitchers, whereas Devin Candy is the alternative. He’s received a really excessive arm angle that creates a ton of vertical motion on his fastball. He additionally has a cool changeup form that has an enormous velocity and motion separation from that fastball. Early Spring Coaching hasn’t gone properly for him, and he’s had issues throwing strikes, however there’s some actual swing and miss stuff if he can harness it.
