Roger Clemens is widely considered to be the greatest pitcher that has yet to be inducted into the Baseball Hall of Fame. The seven-time Cy Young Award winner has been on hand at the New York Yankees Spring Training, serving as a guest instructor.

‘The Rocket’ was able to take part in a unique pre-game moment ahead of the Yankees matchup with the Philadelphia Phillies on Tuesday. The 11-time All-Star and his son, Kody Clemens, who serves as a utility player for the Phillies, met at home plate to exchange the game’s lineup cards.

The elder Clemens took to X after the game to react to the unique moment, tweeting:

“Don’t know if it was a first time event that a Father / Son exchanged line up cards or not. But I can tell you that it sure was a treat for “The Rocket” doing that with the Kid! Thanks again to “Boonie” (Aaron Boone) and “Topper” (Rob Thomson) for making it happen! @Phillies @Yankees”

The Clemens’ were the second father-son duo to exchange lineup cards in the past four seasons. They join then-Houston Astros manager Dusty Baker and Washington Nationals prospect Darren Baker, who did the same in Spring Training in 2022.

Kody went 1-2 with a run scored on the day, however, Roger’s Yankees won 12-3. The younger Clemens is hitting .333 with one home run, three RBI, and a .933 OPS this spring as he competes for a spot on the Phillies’ Opening Day roster.
