Phillies Complete Deadline Haul: Luis Arraez, Caleb Kilian, and Brooks Raley

Philadelphia didn't make one big splash Sunday. It made two smart ones.

Quick answer: The Philadelphia Phillies acquired second baseman Luis Arraez and right-hander Caleb Kilian from the San Francisco Giants, and separately added left-hander Brooks Raley from the New York Mets.

The trade details

Heavy Sports and deadline trackers had both deals in place Sunday into Monday. The Giants continued a weekend sell-off that also sent Robbie Ray to San Diego and Tyler Mahle to Atlanta, converting multiple veterans into return pieces. New York's Raley move fits the Mets' broader pattern of shipping bullpen arms, the same weekend it also moved Freddy Peralta and Luke Weaver.

What Philadelphia is buying

Arraez is a bat-to-ball specialist without much modern comparison: a lineup piece who almost never strikes out. AthX Engine has him at 303 fantasy points this season, tracking to a 423.74 FP pace, elite production for a contact-first hitter. He slots into a Phillies lineup already featuring Bryce Harper and Trea Turner, giving Philadelphia even more length at the top of the order.

Kilian adds rotation depth behind a top three led by Zack Wheeler, while Raley gives the bullpen a left-handed matchup option, AthX Engine has him at 154.25 FP on the season with a 215.72 FP pace, solid relief production to lean on in October-leverage innings.

What San Francisco and New York are selling, and why

For the Giants, this is part of a broader sell weekend: with the season drifting out of reach, San Francisco is converting veteran talent, Arraez, Kilian, Ray, and Mahle, into younger, controllable pieces across multiple trade partners. For the Mets, Raley is the third bullpen or rotation piece dealt in the same 24-hour window, continuing a clear message from the front office about where this season is headed.

AthX Engine angle

Arraez's contact profile travels with him regardless of ballpark: his 303 FP and 423.74 pace reflect a full season of at-bats that don't disappear because of a jersey change. Kilian and Raley are role-dependent adds, watch how Philadelphia slots each into an already crowded pitching staff before expecting immediate full-workload production.
