Who did Red Sox send to Cardinals to complete Sonny Gray trade?

In late November, the Red Sox made their first of two significant offseason trades with the Cardinals, acquiring veteran starter Sonny Gray and cash considerations for right-hander Richard Fitts, left-handed pitching prospect Brandon Clarke, and a player to be named later or cash considerations.

On Monday, Boston completed the deal by sending minor league righty Patrick Galle to St. Louis, per announcements from both clubs. Galle will report to the Cardinals’ Low-A affiliate in Palm Beach, Fla.

Galle, who turned 22 on Sunday, gets a belated birthday present in the form of a new organization. The Mississippi native was originally selected by the Red Sox in the 17th round (508th overall) of last year’s draft out of Ole Miss. He received an at-slot $150,000 signing bonus.

Following a solid summer (1.04 ERA in 8 2/3 innings) with the Wareham Gatemen of the Cape Cod Baseball League, Galle made his professional debut for Low-A Salem last August. He appeared in three games for Boston’s Carolina League affiliate to end his 2025 season and then returned to the rebranded RidgeYaks to open the 2026 campaign. Altogether, he owns a 4.91 ERA with seven walks to four strikeouts through the first four relief outings (7 1/3 innings) of his pro career.

Listed at 6-foot-2 and 215 pounds, Galle operates with a 95-97 mph fastball that has reached 99 mph, an 89-93 mph cutter, and an 85-88 mph slider. SoxProspects.com, which did not have him ranked among Boston’s top 60 prospects, describes him as a “pure relief prospect with intriguing fastball velocity” who “needs to throw more strikes to be successful in pro ball.”

While sending Galle to the Cardinals completes the Gray deal, the Red Sox still have unfinished business involving players to be named later. They are due to send two players and receive one from the White Sox to finalize the February trade that sent righties Jordan Hicks and David Sandlin to Chicago.
