What happened: During All-Star availability in Philadelphia, Luis Arraez, making his fourth All-Star appearance, stated he will not return to first base or designated hitter if dealt before August 3. Working under infield instructor Ron Washington, the veteran has transitioned full-time to second base while hitting .330 this season. He emphasized that his physical and mental preparation has focused entirely on playing second base as his primary position.
Why it matters: In previous seasons with the Miami Marlins and San Diego Padres, his defensive assignments at first base and designated hitter depressed his overall value due to his limited power. By establishing himself as a reliable second baseman this season, he has already accumulated 3.0 WAR, surpassing his combined 2.6 WAR across the previous two campaigns. The positional demand narrows his potential trade destinations, but protects his defensive value as he approaches winter free agency.
By the numbers: Arraez is batting .330 this season with 3.0 WAR accrued through the first half of the schedule. Across the 2024 and 2025 seasons with Miami and San Diego, he recorded 381 hits but generated just 2.6 combined WAR while playing primarily off second base. San Francisco currently holds a 41-55 record entering the All-Star break.
What to watch: With the August 3 trade deadline approaching, acquiring clubs seeking middle-infield offensive upgrades must evaluate whether their roster flexibility allows playing him exclusively at second base. His market trajectory will clarify over the next three weeks before he enters unrestricted free agency this winter.
