Scouting Report
Updated May 19, 2026
Brennen Davis, a former top prospect for the Chicago Cubs, is proving himself with the Seattle Mariners after signing a minor league contract in the offseason. Despite a hamstring strain suffered in mid-March, Davis has excelled at Triple-A Tacoma with a .293/.404/.569 slash line, 8 home runs, and a 145 wRC+ in 35 games. He was selected to the 40-man roster on May 18 and optioned to Triple-A. Davis has an assignment deadline and an August 1 opt-out clause in his contract, creating urgency for the Mariners to either promote him or risk losing him to another organization. His strong performance and right-handed power have made him a valuable prospect for the organization.
