The Giants shipped up homegrown lefty Kyle Harrison to Boston in a deal that brought Rafael Devers to the Giants.

The deal also included outfielder James Tibbs III, last year’s first-round selection, and 20-year-old right-hander Jose Bello. Despite Devers’ talents, the Giants kept Bryce Eldridge, their top overall prospect, and left-hander Carson Whisenhunt, their top pitching prospect.

The press conference will be held at Oracle Park in San Francisco at 5:30 p.m. EST (2:30 p.m. PST) and will feature a panel of Giants chairman Greg Johnson, president of baseball operations Buster Posey, general manager Zack Minasian, manager Bob Melvin, and of course, Devers himself.
