However, 20-year-old rookie Roman Anthony crushed a home run off Skenes last month. The ball traveled over 400 feet and had an exit velocity of 108.6 mph.After the 4-2 Pirates win, Skenes shared his thoughts on Anthony."He (Roman Anthony) is a good player, obviously, hitting leadoff for one of the best teams in the AL. What is he, 21? Doesn't look like a 21-year-old, so, yeah, he's going to keep this offense running for a long time," Skenes said.With both players in their early 20s, more intense matchups like this are likely to occur in the near future.
