The Red Sox's "Big Three" prospects in Roman Anthony, Kristian Campbell, and Marcelo Mayer all homered on Thursday night.

After Kristian Campbell and Marcelo Mayer hit back-to-back home runs, Roman Anthony blasted one of his own during the Boston Red Sox's Speak Breakout game against the Tampa Bay Rays.

Red Sox second baseman Kristian Campbell - MLB Pipeline's No. 7 overall prospect - got things going with two outs in the Top of the 3rd when he launched a two-run homer to deep right center off Rays No. 11 prospect Trevor Harrison.
