• Rays' Ben Williamson: Heading to Tampa Bay

  Rotowire Feb 2, 2026

  The Rays acquired Williamson from the Mariners on Monday as part of a three-team trade involving the Cardinals, Adam Jude of The Seattle Times reports. Brendan Donovan is headed to Seattle as part of the deal. Williamson is a glove-first third baseman who slashed just .253/.294/.310 with one homer in 85 regular-season games for the Mariners in 2025. He is now stuck behind Junior Caminero in Tampa Bay, so Williamson could begin the 2026 campaign at Triple-A Durham.

• Mariners' Ben Williamson: Records fifth steal

  Rotowire Jul 27, 2025

  Williamson went 1-for-4 with one RBI and one stolen base in Saturday's 7-2 win over the Angels. Williamson has started to make a larger impact on the basepaths with three steals over his last six games. He's still not doing much else, though -- during that span, he's gone 5-for-20 (.250) with two RBI, one walk and no extra-base hits. That's right in line with his production all year, as he's batting .254 but he has a poor .598 OPS with five steals, one home run, 21 RBI and 35 runs scored as a fixture at the bottom of the Mariners' lineup.

• Mariners' Ben Williamson: Logs steal in loss

  Rotowire Jul 22, 2025

  Williamson went 2-for-3 with a stolen base in Monday's 6-0 loss to the Brewers. Williamson had gone 0-for-8 over his previous three games, and this was just his second multi-hit effort in July. The rookie third baseman continues to earn his playing time through steady defense rather than big contributions on offense. For the season, he's slashing .259/.293/.319 with one home run, 19 RBI, 35 runs scored and three steals across 76 contests, giving him minimal upside as a contact hitter with little pop at the bottom of the order.
