When a player changes franchises, the conversation usually stops at the headline. The deal gets graded, the fit gets debated, and everyone anticipates their debut next season.
But for fantasy managers, the real question comes after the dust settles and situation drives value. Ballpark changes and supporting cast swaps.
This is about diving into the details of the transaction itself and focusing on what actually matters for 2026. How does a change in scenery impact expectations for these players going forward?
Playing Time – Are they guaranteed an everyday role on their new team?
Park Factors – Is their new home more pitcher-friendly or hitter-friendly?
Supporting Cast – How has the quality of the roster around them changed?
Using this simple exercise, we can grade some key trades this winter and weigh our opinions for this upcoming season.
Nolan Arenado – 3B, Arizona Diamondbacks
The 57.8 career WAR veteran moves significantly closer to his hometown in this deal, joining a club on the cusp of postseason contention. Nolan Arenado gets a meaningful boost from a ballpark perspective, leaving a stadium that grades around league average and landing in one of the more favorable hitting parks in baseball, according to Baseball Savant. While the move may seem to be favorable to a declining Arenado, based on Expected Home Runs by Park in 2024 and 2025, suggest that he would have actually hit 2 less homeruns at Chase Field. He also steps into a top-heavy lineup featuring Geraldo Perdomo, Ketel Marte, and Corbin Carroll occupying the top three spots, providing consistent table-setting opportunities. Arenado should face no competition, locking in everyday playing time. He’s projected to hit sixth, a role that’s become familiar late in his career. Across the 2024 and 2025 seasons, he logged 184 combined plate appearances from the six-hole. He’s produced a .273 OPS and a .182 SLG in 11 PA last season at Chase Field over his entire career. After five seasons and just three playoff appearances in St. Louis, Arenado seems to slightly improve his fantasy value after joining the organization where close friend and longtime teammate Paul Goldschmidt first made his mark, as he chases potentially one more meaningful October run. It’s difficult to know what to do with Arenado heading into 2026, the decline is real and obvious, but his resume keeps fantasy managers hoping for a taste of his prime again. Ultimately, in a 12-team league, it’s hard to see him make a meaningful impact which so many better options available at third base.
MacKenzie Gore– SP, Texas Rangers
Rising left-hander MacKenzie Gore takes his talents to the Lone Star State, landing in a significantly more pitcher friendly environment. Globe Life Field grades in the bottom portion of park factor rankings, a clear upgrade from Nationals Park, which consistently skew towards offense. Gore joins an already loaded rotation headlined by future hall of famers Nathan Eovaldi and Jacob deGrom, with emerging arm Jack Leiter rounding out the group. His presence adds much-needed left-handed balance to a staff built largely around right-handed power arms. Texas also strengthened the offense this winter with the addition of Brandon Nimmo, a move that should provide more consistent run support than Gore saw in Washington, assuming reasonable health across the roster. Across the board, this is a clear upgrade for Gore from a fantasy perspective. He departs a rebuilding organization and steps into a competitive roster aiming to recapture the success of its 2023 run, after his success last season and upgrade on home parks, it boosts his fantasy value heading into 2026. The biggest question for Gore’s 2026 fantasy value is durability and consistency, given the blatant second-half fade in 2025. Gore started the year out trailblazing, starting the year without an appearance under 5.0 innings pitched until mid-April. Over the full season he threw 159.2 innings with a 4.17 ERA and 185 strikeouts, but there was a rough split as the year went on, after a strong first half with his ERA sitting near league average, post All-Star break the inconsistencies bled through. Command issues triggering a higher ERA and walk rate. Yet, being surrounded by seasoned veterans like Eovaldi and deGrom, should help him pace workload and boost experience. It is clearly one of the best upgrades for a starting pitcher compared to other moves. We’ve seen the potential from Gore, and I could see him being a solid SP4 for your 12-man league roster with some upside to be set-and-forget in your rotation.
Sonny Gray lands in a crowded rotation on a franchise that has made more than a few questionable moves in recent history. He won’t be the standalone ace he was in St. Louis, now joining a staff anchored by Garrett Crochet and Ranger Suárez, both who have locked-in rotation spots. Behind them, homegrown arms like Brayan Bello, Payton Tolle, and Connelly Early are all competing for innings, and that’s only part of the logjam…At 34 years old, Gray simply can’t assume a guaranteed role. I believe in Gray to solidify a role in this rotation, but the environment isn’t doing him any favors. He moves into Fenway Park, one of the most hitter-friendly venues in baseball history, ranking second behind only to Coors Field in park factors. If that wasn’t enough, Gray’s history at Fenway Park is atrocious. In three specific appearances there, he’s posted ERAs of 10.80, 10.80, and 17.18, allowing 20 earned runs per start, Yikes! That’s a huge shift for a pitcher who benefitted from far friendlier conditions in Busch Stadium. While the lineup has added the bat of Willson Contreras and features rising young talent in Roman Anthony, Jarren Duran, Marcelo Mayer, and Triston Casas, he does find an upgrade in lineups compared to the Cardinals. There are still questions about batting success and fielding ability. After losing Rafael Devers last season and Alex Bregman this winter, Gray finds himself in a brutal AL East, pitching in a dangerous park, with an intense fanbase, and an uncertain supporting cast. From a fantasy standpoint, it may be hard to find any upgrades to his new situation, but what I do know is that Sonny Gray is a true work horse. He’s stacked up 3 seasons in a row with at least 166 IP with two of those seasons being over 180 IP! He has always been one of the better strikeout-to-walk ratio pitchers which is the formula you need in an environment like Fenway. Boston’s pitching staff is already tweaking his pitch mix, enhancing his sweeper and curveball, hoping to stabilize WHIP and limit damage in Fenway. In 2026, he’s projected a strong xFIP at 3.44 and even finished below 4.00 last year. I believe in Sonny Gray’s ability to overcome the tough environment in Boston and project him to be a solid SP3 with upside.
Edward Cabrera – SP, Chicago Cubs
Edward Cabrera had a good season for the Marlins last year, peaking career highs in both innings pitched and strikeouts. While his limited history at Wrigley Field doesn’t show much other than some strong strikeout totals, which makes him a fantasy value. The fastball remains ta struggle for Cabrera. According to Run Values by Pitch Type, Cabrera improved it slightly, moving from a lousy -9 to -8, and still allowed a .553 SLG against the pitch last season. Both his changeup and curveball is where he thrives, emerging as his most efficient pitches by run value. Boasting an elite 44.3 strikeout percentage. Last year, he recorded the lowest average arm angle of his career while produced his highest Whiff rate of his career on his curveball at 45.2%. To reach the next tier of success, he will likely need either his sinker or four-seam to improve. Destination wise, he’s set up for success. Despite the departure of Kyle Tucker, Cabrera lands in a stronger lineup and benefits from a park upgrade in Wrigley Field. He should have an expected spot next to his rotation mates Shota Imanaga, Matthew Boyd, and Jameson Taillon with consistent innings next season. Although he’s improved his environment, I still think you’ll be able to get him at a cheaper rate with plenty of upside. Making him a sleeper draft pick, similar Gore.
Brandon Lowe – 2B, Pittsburgh Pirates
Brandon Lowe is one of the more underrated transactions this offseason that I was excited to cover. On the surface, I see how it might not look like an upgrade, but this has real sneaky upside written all over it. Playing time should improve. Not that Lowe’s situation in Tampa Bay was solidified, but Pittsburgh’s infield is far thinner in both talent and depth. Lowe should slide right in as the leader of a struggling infield and become an important piece to this lineup. Although, PNC Park graded near last in in HR factor for LHH, I chose to be optimistic with Lowe. With the Rays returning to a renovated Tropicana Field after last season temporary setup, I’m pulling park factors from 2024, the most recent year played in the actual dome. Using that baseline, the park-factor shift is massive: from 28th to 6th. landing in PNC Park. That matters a lot to a hitter like Lowe, using Expected Home Runs by Park from that same 2024 data, Lowe was projected to hit five more home runs in PNC Park than at Tropicana Field. He should easily be a right field short-porch merchant with his power. He’s projected to hit in the two-hole and should be a good pair with Bryan Reynolds. Lowe should see more plate appearances and RBI opportunities, boosting his fantasy outlook. When you factor in his power at an increasingly thin second base position, Lowe starts to look like a legitimate sleeper candidate heading into next year’s draft.
