Angels slugger Mike Trout used MLB’s second annual Players Weekend to pay tribute to his brother-in-law Aaron Cox by placing his name on the back of his jersey for Friday’s game against the Astros.

Cox, who turned 24 on Aug. 5, died Aug. 15.

Trout was playing in his first game since Aug. 1, and A.COX was stitched atop his No. 27 jersey. As part of Players Weekend, all players are allowed to choose the name they want displayed. In addition to missing time because of Cox’s death, Trout had been on the disabled list because of right wrist inflammation.

Trout had been expected to have “Kiiiiid” as his nickname, ESPN reported, but he changed his mind Friday on the way to the stadium. 

“It meant a lot,” Trout said, per ESPN. “I didn’t really tell anybody I was doing it. I just came in here, I told (clubhouse manager) Keith (Tarter) before the game, ‘It’d be cool to honor him tonight.’ It was special. He was obviously a brother-in-law to me, but he was one of my closest friends.”

Cox also was a pitcher in the Angels’ farm system and appeared in 11 games in 2018 for the High-A Inland Empire 66ers. A moment of silence was observed in Cox’s memory before the game at Angel Stadium. 

Trout was 2-for-3 in his return, including a triple in the first inning. The Astros won 9-3.
