Tony Clark says Major League Baseball has done a poor job of marketing Mookie Betts, the reigning American League MVP.

"Mookie should be a household name," said Clark, the head of the players' union. "Mookie should be a one-name guy. You say Ronaldo. You say Messi. You say Mookie. You should know who Mookie is, and outside of the baseball world, I don't know how many do."

Betts made his fourth-straight All-Star team this month.

"In the grand scheme of things with respect to players that should be at the forefront of every conversation and should be in conversations even with non-baseball fans, Mookie is one of them," Clark said. "No doubt about it. And unless or until we fix that, it's going to be difficult for others to be a part of that conversation, too."
