The Mariners selected Williamson's contract from Triple-A Tacoma on Sunday.
ANALYSIS
Though he's not in the lineup for Sunday's game against the Rangers, Williamson could end up getting a long look at third base while Jorge Polanco remains limited to DH duties due to side soreness. The 57th overall pick in the 2023 First-Year Player Draft, Williamson compiled a .769 OPS and stole 19 bags in 25 attempts over 541 plate appearances between Double-A Arkansas and High-A Everett in 2024. He was slashing .281/.317/.333 with three extra-base hits (all doubles) and two stolen bases over 14 games for Tacoma prior to being called up.
