The Rays ended up in a blockbuster four-player trade with Milwaukee as shortstop Willy Adames and right-hander Trevor Richards went to the Brewers while relievers J.P. Feyereisen and Drew Rasmussen head to Tampa Bay, according to ESPN's Jeff Passan.
The Rays are loaded with shortstop potential in their Triple-A affiliate Durham Bulls, which includes top prospect Wander Franco, Taylor Walls and Vidal Brujan, who just hit his sixth homer of the season.
But Tampa Bay decided to skip over their top prospect and call up Walls for Saturday's game, according to MLB.com's Adam Berry.
