2026 Fantasy Outlook
Williamson appeared to have a chance to begin 2026 as a starting infielder for the Mariners, but his trade to the Rays complicates his path to immediate playing time. Williamson did not exactly make the most of his opportunity last season as he saw 85 games with the club and had 14 extra base hits as a rookie. Williamson has been a good contact and patient hitter in his time with the organization, but he has hit just nine homers in 825 professional plate appearances over the course of those three seasons. Williamson would ideally profile as a reserve infielder off the bench rather than an everyday starter because he has the defensive skills to play anywhere on the infield in a pinch. If you liked Matt Duffy years ago, then you'll enjoy Williamson on your roster. Mixed league managers can rightfully scroll past him in the draft room queue. Read Past Outlooks
Signed a one-year contract with the Mariners in April of 2025. Traded to the Rays in February of 2026.
Turning heads in camp
Williamson has impressed manager Kevin Cash this spring with his ability to handle second base and shortstop in addition to his burgeoning power, Ryan Bass of FanDuel Sports Network Sun reports.
Analysis
"The bat has really come to life," Cash said of Williamson. "He's a big, strong guy and the power has kind of showed up here. He's had some big at-bats and drives the ball well, so it looks like he can really help us." Acquired this offseason from Seattle, Williamson is hitting .375 with two home runs, two steals and a 5:4 K:BB in 36 plate appearances this spring. While the righty-hitting Williamson figures to be in the lineup against lefties, his strong spring and quality defense at multiple positions opens the door for him to find work against righties as well.

How does Ben Williamson compare to other hitters?
This section compares his stats with all batting seasons from the previous three seasons (minimum 400 plate appearances)*. The bar represents the player's percentile rank.

Latest Fantasy Rumors
Heading to Tampa Bay
Williamson is expected to be traded to the Rays as part of a three-team deal involving the Mariners and Cardinals, Bob Nightengale of USA Today reports.
Analysis
Brendan Donovan is headed to Seattle as the main piece in the trade, and prospects will presumably be sent to St. Louis. Williamson had been viewed as the favorite to open the season as the Mariners' starting third baseman but will now be blocked at that position in Tampa Bay by Junio Caminero. The 25-year-old Williamson is a terrific defender at the hot corner, but his bat lags well behind. He slashed just .253/.294/.310 with one homer in 85 regular-season games for the Mariners in 2025.
