Red Sox To Sign Isiah Kiner-Falefa - MLB Trade Rumors

By Anthony Franco | February 4, 2026 at 8:30pm CDT The Red Sox reportedly have an agreement with infielder Isiah Kiner-Falefa on a one-year contract that guarantees $6MM, pending a physical. There are an additional $500K in incentives available for the ALIGND Sports Agency client. Boston’s 40-man roster will be at capacity after the signing, so no corresponding move is required. Kiner-Falefa will apparently be the Sox’s answer at second base after they lost Alex Bregman to free agency. Boston kicked around much bigger possibilities on the trade and free agent markets (e.g. Ketel Marte, Brendan Donovan, Isaac Paredes, Bo Bichette) but couldn’t find a deal to their liking. They reportedly prefer to keep Marcelo Mayer at third base and were looking for a quality defensive player whom they could plug in at the keystone. A former Gold Glove winner, Kiner-Falefa qualifies on that front. He took home the defensive honor at third base as a member of the Rangers in 2020. He’s a plus defender at any of second base, third base or shortstop. He has more experience on the left side of the infield but carries strong marks from Defensive Runs Saved (+12) and Statcast (+2 Outs Above Average) in nearly 600 career innings as a second baseman. The flip side is that Kiner-Falefa isn’t going to provide much at the plate. He puts the ball in play but has some of the lowest exit velocities in the sport. He has never reached double digits in home runs in a season, nor has he turned in a .700 OPS in any of his eight years in the majors. Kiner-Falefa is coming off a .262/.297/.334 showing across 459 plate appearances between the Pirates and Blue Jays. He’s a .262/.311/.349 hitter in more than 3300 trips to the dish over his career. He’s a solid baserunner despite average speed, stealing double digit bases in each of the past five years. Second base was a weak point for the Red Sox last year. Kristian Campbell faded after a monster April and was back in Triple-A by the end of June. He posted disastrous defensive grades and no longer seems to be an option at the position. Chief baseball officer Craig Breslow has suggested a few times they view Campbell primarily as an outfielder. He’s a good enough athlete to have some promise as a defender on the grass, but Boston’s crowded outfield isn’t going to afford him many opportunities until someone suffers an injury. The Sox used Romy Gonzalez, Ceddanne Rafaela, David Hamilton and Nick Sogard there in the second half and got just a .242/.292/.333 showing down the stretch. Rafaela is an elite defensive outfielder whom the Red Sox prefer to play in center field. Gonzalez hits lefties well but profiles as a short side platoon bat. Hamilton and Sogard are utility players on a team that expects to contend. Kiner-Falefa probably should be as well, yet there weren’t any clear regulars available in free agency at this stage of the offseason. Kiner-Falefa is a right-handed hitter whose offensive profile doesn’t change regardless of the pitcher’s handedness. Gonzalez should still take the majority of at-bats against lefty pitching. Kiner-Falefa could slide to third on those days if the Sox want to shield Mayer from same-handed opposition. They might also prioritize having him on the field behind ground-ball pitchers like Brayan Bello and Ranger Suárez while plugging Gonzalez in for a little more offense on days when Garrett Crochet or Sonny Gray take the mound. It appears the Sox had pushed close to their financial comfort zone after signing Suárez and trading for Gray and Willson Contreras. According to RosterResource, this pushes Boston to roughly $263MM in luxury tax commitments. They’re a few days removed from giving up a mid-tier starting pitching prospect, David Sandlin, to dump $16MM of the $24MM remaining on the Jordan Hicks contract on the White Sox. (Boston also picked up minor league pitcher Gage Ziehl in that trade.) If the cash considerations are evenly distributed, they saved $8MM on the 2026 payroll, some of which they’re now reallocating to Kiner-Falefa. The Sox are above the $244MM first tax threshold. They’re second-time payors who pay a 30% tax on their first $20MM in overages, so they’re currently set for a minimal tax bill. That was also the case last year, as they paid a $1.5MM fee for going nearly $8MM above the line. The tax rate climbs to 42% for spending between $264MM and $284MM. There are no draft penalties associated with going into the second penalization tier, so that’d largely be an arbitrary stopping point if that’s where ownership sets the budget. The Kiner-Falefa signing comes with a $1.8MM tax hit. Chris Cotillo of MassLive first reported the Red Sox and Kiner-Falefa were nearing a one-year deal. ESPN’s Jeff Passan confirmed an agreement was in place. Cotillo reported the $6MM guarantee and $500K in bonuses. Image courtesy of Stephen Brashear, Imagn Images.
