Core Event
On the morning of the MLB trade deadline (August 3, 2026), the Philadelphia Phillies received three-time batting champion Luis Arraez and right-handed reliever Caleb Kilian from the San Francisco Giants. In return, San Francisco acquired pitching prospects Ramon Marquez and Marty Gair. The trade was confirmed by ESPN’s Jeff Passan and USA Today’s Bob Nightengale.
Background & Context
The Giants entered the deadline with a 47-65 record and several expiring contracts. Arraez, a four-time All-Star who signed a one-year, $12 million deal with San Francisco in February, was leading the NL with a .324 average and a .360 on-base percentage. His defense at second base had improved, raising his Outs-Above-Average to +11.
Philadelphia, at 59-53 and chasing a wild-card spot, had the league’s second-worst on-base percentage (.304) and needed a high-contact hitter to protect Bryce Harper and Kyle Schwarber. The Phillies also added bullpen depth with Kilian, who posted a 4.26 ERA and eight saves for the Giants.
