The Giants made a difficult, yet expected move.San Francisco traded All-Star second baseman Luis Arraez and relief pitcher Caleb Kilian to the Philadelphia Phillies on Monday, the team announced after ESPN’s Jeff Passan and The Athletic’s Jayson Stark first reported the news.
The Giants received pitching prospects Ramon Marquez and Marty Gair in the deal with the Phillies.
San Francisco signed Arraez to a one-year, $12 million free-agent contract last offseason. Despite initial concerns regarding the veteran second baseman’s defense, Arraez quickly proved to be a more than serviceable defender at the position after working with Giants infield coach Ron Washington.
However, his biggest impact throughout the first half of the 2026 MLB season was with the bat. In 105 games with San Francisco before the trade, Arraez batted .324/.360/.440 with four home runs, 43 RBI and 10 stolen bases, earning him his fourth career All-Star nod.
With Arraez on the move and Casey Schmitt on the injured list with a torn left meniscus, the Giants likely will use Christian Koss and Osleivis Basabe at second base.
