Luis Arraez will play for his fourth team in three seasons, as the San Francisco Giants reportedly traded the All-Star infielder to the Philadelphia Phillies, per The Athletic. The Phillies are also receiving reliever Caleb Kilian, and sending the Giants pitching prospects Ramon Marquez and Marty Gair, also per The Athletic. This move concludes Arraez's short stint in San Francisco.
He joined the Giants out of free agency prior to the 2026 season, agreeing to a one-year deal, worth $12 million. Through 103 games, he's delivered an NL-best .324 batting average. But with the Giants (47-62) in a noncompetitive position, the organization shipped him to a contender.
Regardless of where he's playing, Arraez has consistently produced at the plate. Over seven-and-half seasons, he has a career .318 batting average. He won the batting title with the Miami Marlins in 2023.
However, he hasn't always been reliable on the defensive side, reflected in his career average 3.4 WAR. In 2026, he's turned that around. After primarily playing first base with the San Diego Padres, he returned to second base in San Francisco, and flourished: Arraez has been worth 3.1 wins above replacement alone in 2026, thanks to the defensive improvement.
The Phillies have struggled with defense up the middle, thanks to shortstop Trea Turner, who has also been scuffling at the plate – Turner is batting just .250/.299./404, for a well below-average 87 OPS+ in addition to the defensive issues. Bryson Stott, Philadelphia's primary second baseman, is also a shortstop, however, so the addition of another second baseman allows for a possible shift to remove Turner's glove from the equation. Arraez, 29, will resurface on the free-agent market after the 2026 season.
Marquez is a 20-year-old starter in the minors, currently striking out 14.2 batters per nine across Single-A and High-A in 2026. Gair is 22 and a reliever with strikeout stuff – he has punched out 66 batters in 36 innings across two Single-A levels in 2026 – but he also struggles with his control: despite striking out 15.1 batters per nine over his minor-league career, his K/BB is just 1.89.
