Boston Red Sox fans keep hoping top prospect Roman Anthony gets promoted to the majors.

What he did for Triple-A Worcester on Saturday night was the latest evidence of why.

Anthony, ESPN's No. 1-rated prospect , smashed a 497-foot grand slam for the WooSox in a 10-4 victory over Rochester during an International League game in Worcester, Massachusetts.

The 21-year-old put the WooSox ahead 9-4 in the eighth inning when he drove a 91.1 mph sinker from Carlos Romero deep over the right-center-field wall, a drive that left his bat at 115.6 mph.

According to Statcast, that was the longest home run in affiliated baseball this season.

"Got it and didn't really miss it," Anthony said, according to the Telegram & Gazette of Worcester . "So, it felt great."
