SCOTTSDALE, Ariz. — The Rockies held the finals of their titanic table tennis championship Tuesday morning in the packed weight room at Salt River Fields. OK, so it wasn’t quite Bjorn Borg vs. John McEnroe or Roger Federer vs. Rafael Nadal, but it was epic, nonetheless. When the cheering stopped and the trash talking ceased, the doubles team of Charlie Blackmon and Chris Rusin beat the tandem of Nolan Arenado and Zach Wilson, the Rockies’ farm director, in three games.
