The struggling Arizona Diamondbacks shook up their roster Friday, promoting their top prospect, outfielder Ryan Waldschmidt, from Triple-A and designating veteran outfielder Alek Thomas for assignment.

The 23-year-old Waldschmidt, who nearly made the team out of spring training, was batting .289 with three homers, 22 RBIs and had a .877 OPS at Triple-A Reno. He was the 31st overall pick in the 2024 draft out of Kentucky.
