Previewing The 2025-26 Free Agent Class: Left-Handed Relief

All but two teams have already turned their attention toward the offseason. Identifying free agent targets is a big part of that prep work, so it’s worth taking a look at the players who’ll be available at each position.

The 2025-26 class of left-handed relievers is thin on high-leverage arms but has plenty of solid, serviceable veterans — plus a few wild cards who could pursue a big league return after pitching overseas. Ages listed are for the 2026 season.

Previous entries in this series: catcher, first base, second base, third base, shortstop, center field, corner outfield, designated hitter, starting pitching, right-handed relief

Veteran Setup Arms

Jalen Beeks (32)

Beeks took a minor league deal with the Astros last offseason but opted out late in spring and signed a major league contract with the D-backs. It panned out well. He pitched 57 1/3 innings, logged 14 holds and a save, and fanned 20.3% of his opponents against an 8.7% walk rate — all en route to a 3.77 ERA. Beeks sits 94.4 mph with his four-seamer, posted an above-average swinging-strike rate in 2025, and has pitched primarily in medium to high-leverage spots over the past four years. He won’t break the bank but should get a modest one-year deal.

Danny Coulombe (36)

Coulombe, who just turned 36 yesterday, was terrific in 31 innings with the Twins (1.16 ERA, 25.4 K%, 7.4 BB%) but struggled in 12 innings after being traded to the Rangers (5.25 ERA, 22.2 K%, 16.7 BB%). An IL trip due to shoulder fatigue didn’t help his time with the Rangers, and Coulombe also had a three-week IL stint due to a forearm strain with Minnesota in May. Coulombe’s average four-seamer and sinker barely crack 90 mph, but he has a 2.60 ERA with strong strikeout and walk rates in 173 1/3 innings dating back to 2020. He made $3MM this year, and another affordable one-year deal seems likely.

Caleb Ferguson (29)

Ferguson’s one-year, $3MM deal proved to be a sound investment for the frugal Pirates, who flipped him to the Mariners at the deadline after a solid four-month run. Ferguson was effective with both clubs, pitching to a combined 3.58 ERA. His 18.9% strikeout rate was below average, but Ferguson’s 8.1% walk rate was solid and no reliever in baseball limits hard contact as well as he does. His 27.7% opponents’ hard-hit rate was the best in baseball, and he sat in the 99th percentile in average exit velocity and barrel rate. Ferguson doesn’t have plus command or generate whiffs at a plus rate, but he’s young, durable and relatively consistent. He could be a candidate for a multi-year deal with a low average annual value.

Hoby Milner (35)

Milner topped 64 innings for a fourth straight season, tossing 70 1/3 innings with a 3.84 ERA for the Rangers. He’s a soft-tossing lefty with a below-average strikeout rate, good command and a plus ground-ball rate. He’s worked a lot of middle relief in the past, but the Rangers used him as one of their go-to setup options for much of the ’25 season and he logged a career-high 18 holds (topping his previous best of 17 with the ’23 Brewers). Milner signed a one-year, $2.5MM deal with Texas last winter and should land in that general vicinity again.

Drew Pomeranz (37)

Welcome back, Drew Pomeranz. The 36-year-old lefty signed a minor league deal with the Mariners and was flipped to the Cubs for cash in April. With Chicago, he made his first big league appearance since 2021 — but it was far more than a quick cameo. The former No. 5 overall draft pick dominated with a 2.17 ERA, 28.1% strikeout rate and 7.4% walk rate in 49 2/3 frames. Pomeranz was one of Craig Counsell’s most trusted relief arms in the playoffs. He’ll be 37 in November, so he’s not likely to snag a multi-year deal, but a big league contract should be waiting for Pomeranz this winter.

Taylor Rogers (35)

Though his All-Star days are behind him, Rogers has been a solid middle reliever for three years running. His teams haven’t used him regularly in high-leverage spots, but he has a 3.16 ERA, 26.4% strikeout rate and 10.2% walk rate since 2023. Rogers’ 92.7 mph average sinker is down a full three miles from its 2021 peak, but his results and track record should get him a big league contract.

Gregory Soto (31)

Soto might have the most earning power among this winter’s crop of lefties due to both his age and his power repertoire. He’s one of the game’s hardest-throwing lefties but doesn’t generate the whiffs one would expect despite that fact. Soto is serviceable every year but has never broken through despite plus velo and a plus swinging-strike rate. Soto has had command troubles in the past but has posted nice walk rates in two of the past three seasons. A two-year deal at market value setup money seems possible.

Caleb Thielbar (39)

Thielbar’s first season with any team other than his hometown Twins was a success. He pitched 58 innings of 2.64 ERA ball for the Cubs and tied Brad Keller for the team lead with 25 holds. Thielbar’s 2024 season was ugly, but he’s posted an ERA of 3.49 or better every other year since 2020. He has average velocity, good command and an above-average strikeout rate, but he’ll be 39 in January, so a one-year deal is the strong likelihood.

Justin Wilson (38)

Wilson missed nearly all of 2022-23 due to Tommy John surgery, struggled with the Reds in 2024, and bounced all the way back in Boston this year. The Red Sox got him on a one-year, $2.25MM deal last winter, and Wilson responded with 48 1/3 innings, a 3.35 earned run average, a 27.5% strikeout rate, a 9.7% walk rate and 18 holds. He should get another one-year deal this winter, probably with nice little bump in salary.

Swingmen/Multi-Inning Arms

Sean Newcomb (33)

“Sean Newcomb, multi-year deal candidate” probably wasn’t on too many bingo cards back in March, but the 2025 season was excellent for the former top prospect and starter-turned-reliever. Newcomb tossed 92 1/3 innings with a 2.73 ERA for the Red Sox and A’s. He started five games and frequently worked multiple innings — sometimes as a bulk reliever after an opener. The 2014 first-rounder punched out 23.3% of his opponents versus a 7.9% walk rate — both slightly better than average. Newcomb has easily earned himself a major league deal, and a modest two-year deal seems plausible.

Ryan Yarbrough (34)

Yarbrough’s 2025 season was par for the course by his standards: eight starts, 11 relief outings, a mid-4.00s ERA, below-average strikeout rate and solid command. That’s what Yarbrough brings to the table most years, and while it’s not a skill set that’s going to get him paid all that highly, it keeps him on big league rosters as a sixth starter/long man in the bullpen on a yearly basis. Yarbrough averages 87-88 mph but induces heaps of weak contact.

Possible NPB Returnees

Foster Griffin (30)

Griffin is a former first-round pick of the Royals who made seven MLB appearances between 2020-22. He has spent the past three seasons in Japan, combining for a 2.57 ERA across 315 2/3 innings. Griffin missed time this past season with what MLBTR has learned was a bone bruise in his lower half. He’s expected to have a normal offseason and intends to pursue an MLB return. Griffin didn’t have overpowering stuff during his initial run in affiliated ball, but he’s coming off a 1.62 ERA while striking out a quarter of opponents. He could command a big league deal to compete for a back-of-the-rotation spot.

Anthony Kay (31)

A former first-round pick, Kay has spent the past two seasons with the Yokohama DeNA BayStars in Japan’s Nippon Professional Baseball. He’s worked out of their rotation, logging a 3.42 ERA in ’24 and a 1.74 mark in ’25. Kay isn’t missing bats at a particularly high level (20.8 K%), but he had good command and a nice ground-ball rate overseas. Big league scouts have been watching him, and while he might get the chance to start somewhere, other clubs will probably be interested in bringing him aboard in a swingman capacity. Either way, he’s at least a candidate for a major league deal.

Options/Opt-Outs

• Jose Alvarado (31) – $9MM club option with a $500K buyout

An 80-game PED suspension cast a cloud over Alvarado’s 2025 season, but the hard-throwing southpaw has been one of the Phillies’ best relievers for several years. Dating back to 2022, Alvarado touts a 3.25 ERA and has fanned 31.7% of his opponents while averaging 98.7 mph on his sinker and 93.1 mph on his cutter. He’d easily top that net $8.5MM in free agency, so the Phils should pick this up.

• Tim Hill (36) – $3MM club option with a $350K buyout

Hill, 36 in February, is a ground-ball specialist who misses almost no bats but rarely walks opponents. He’s logged a 2.68 ERA and kept about two-thirds of the batted balls against him on the ground in 111 innings since joining the Yankees in 2024. This feels like a nice value for the Yankees, even with their luxury tax status.

• A.J. Minter (32) – $11MM player option

Minter underwent lat surgery back in May after pitching only 11 innings. The recovery timetable for him is still a bit murky, but he seems likely to pick up that $11MM option, return to the Mets and aim for better health next year.

• Wandy Peralta (34) – $4.45MM player option (contract also contains $4.45MM player option for 2027)

Peralta posted a 3.14 ERA in a career-high 71 2/3 innings with a career-best 59.7% ground-ball rate in 2025. His 20.1% strikeout rate and 9.6% walk rate were worse than average. Peralta still averages better than 95 mph on his sinker, but he’ll be 35 in July and was used largely in low-leverage spots. It’s likelier than not that he picks up his player option.

• Brooks Raley (38) – $4.75MM club option with a $750K buyout

Raley returned from Tommy John surgery to toss 25 2/3 innings with a 2.45 ERA, a 25.3% strikeout rate and a 6.1% walk rate. His sinker’s average velocity had dipped to 88-89 mph in 2023-24, but he was back up to 90.7 mph this year, right in line with his 2021-22 levels in Houston and Tampa Bay. This option is likely to be picked up.

• Brent Suter (36) – $3MM club option with a $250K buyout

Suter posted a career-high 4.52 ERA in 67 2/3 innings this season, snapping a streak of six straight years with a sub-4.00 earned run average. He’s a soft tosser who specializes in weak contact over missing bats. This will probably get bought out, but Suter is a Cincinnati native who’s clearly enjoyed pitching for his hometown club, so perhaps he’d be amenable to returning on a smaller pact.
