The Philadelphia Phillies acquired three-time batting champion Luis Arraez from the San Francisco Giants ahead of Monday’s trade deadline.

The Phillies, who have dropped nine of their last 13 games, are the 29-year-old infielder’s fifth team in five years.

Held out of the Giants’ lineup since Saturday due to cramps, Arraez leads the National League with a .324 batting average through 105 games. He has 23 doubles, seven triples, four homers, 43 RBIs, 52 runs and 10 steals.

The Phillies also received right-handed reliever Caleb Kilian. In exchange, the Giants get right-hander Ramon Marquez — Philadelphia’s No. 4-ranked prospect, per MLB Pipeline — and minor league reliever Marty Gair.

Kilian, 29, is 3-6 with eight saves and a 4.26 ERA in 45 appearances out of the San Francisco bullpen this season.

Marquez, 20, is 6-1 with a 1.68 ERA in 12 games (11 starts) between Class A stops, Clearwater and Jersey Shore. Gair, 23, has pitched for the same two squads in 2026, going 3-3 with a 4.50 ERA and six saves in 30 relief appearances.

Named an All-Star for the fourth time this season, Arraez won three consecutive batting titles with the Minnesota Twins in 2022 (.316), the Miami Marlins in 2023 (.354), and the Marlins and San Diego Padres in 2024 (.314).

Arraez leads all active players with a career .318 batting average to go with 192 doubles, 40 homers, 351 RBIs and 41 stolen bases in 946 games with the Twins (2019-22), Marlins (2023-24), Padres (2024-25) and Giants.

In a separate deal on Monday, Philadelphia acquired veteran reliever Brooks Raley from the New York Mets in return for two prospects.
