The Cubs are eyeing upgrades for the back end of the bullpen and have looked into Orioles setup man Seranthony Dominguez and Rays closer Pete Fairbanks, reports Bruce Levine of 670 The Score. Levine notes that the Rays have been showing reluctance to part with Fairbanks, which lines up with recent reporting from Will Sammon, Katie Woo and Patrick Mooney of The Athletic, wherein they indicate that Tampa Bay “strongly prefers” to hang onto Fairbanks (but are still hearing out interested teams who inquire).
Both Dominguez and Fairbanks are sensible targets for a Cubs bullpen in need of help. Dominguez is being paid $8MM in his final year of club control. He’s a pure free agent at season’s end. The 30-year-old righty is in his first full season with the O’s after having been acquired from the Phillies at last year’s deadline. He’s pitched 40 2/3 innings this season and worked to a sharp 3.32 ERA with a hefty 31% strikeout rate. Dominguez has been one of the primary setup options for closer Félix Bautista, tallying 13 holds and two saves of his own on the season. He’s averaged a sizzling 97.7 mph on his four-seamer and 97.9 mph on his sinker.
Command troubles have plagued Dominguez at times in his career, however, and that’s never been truer than in 2025. This year’s 14% walk rate is far and away the worst of his career, and he’s also tossed nine wild pitches. That’s clearly far from ideal, but Chicago’s combined 20.1% strikeout rate from their relievers is fourth-lowest in MLB, so adding some swing-and-miss is an understandable focus — particularly given how important that ability tends to be in the postseason.
Fairbanks is earning a bit more than $3.8MM this season and has a club option for the 2026 campaign. That option comes with a $7MM base value, but Fairbanks has already boosted that to to $8MM as he begins reaching escalator milestones. So long as he remains healthy, he’ll likely increase that option value considerably more.
The 31-year-old Fairbanks has already finished 29 games and boost next year’s option value by $500K for each of 30, 35 and 40 games finished in 2025. The option also climbs by $1MM apiece when Fairbanks reaches 135, 150 and 165 total appearances from 2023-25 combined. He’s currently at 134 games total between those three seasons. There’s a strong chance that option winds up valued at $11.5MM.
In the past, Fairbanks has missed bats at comparable levels to Dominguez, but his 20.3% strikeout rate in 2025 is a career-low. He’s dealt with shoulder, lat, forearm and hip injuries over the past five seasons, and a four-seamer that once averaged a blistering 99 mph has accordingly dropped off, sitting at 97.3 mph in each of the past two seasons.
Fairbanks’ swinging-strike rate has unsurprisingly dropped as he’s lost some zip on that heater, though his velocity is still well above average and he’s continued to remain effective. In 38 innings this season, he’s sporting a 2.84 earned run average and has gone 17-for-20 in save opportunities. With the exception of 21-inning rookie debut, Fairbanks has never posted an ERA north of 3.59 in a season. This year’s 2.84 ERA is almost a dead match for the 2.88 mark he’s compiled dating back to the 2020 season.
Dominguez and Fairbanks are surely just two of many targets the Cubs are eyeing as they look to bolster a relief corps that ranks 10th in the majors with a collective 3.78 ERA but 27th in strikeout rate, 15th in FIP (4.05) and 24th in SIERA (3.98). Emerging closer Daniel Palencia and resurgent veteran Brad Keller are both showing plus velocity, with the former sitting at a whopping 99.5 mph with his fastball and Keller sitting 97.1 mph. The rest of Chicago’s bullpen — aside from the currently injured Porter Hodge — has average to below-average velocity (and, in many cases, sub-par strikeout rates to match).
