Photos: Mikaela Mayer's impressive victory on ESPN

Mikaela Mayer demonstrated on national TV that she’s one of the best in the business.

The former U.S. Olympic outclassed Helen Joseph (17-5-2, 10 KOs) to win a near-shutout decision in the main event Tuesday inside the MGM Grand bubble in Las Vegas.

Mayer (13-0, 5 KOs) wants a title shot next. She appears to be ready for that.

In the co-feature, the popular Clay Collard (8-2-3, 3 KOs) put an overmatched Lorawnt T Nelson down three times and stopped him at 1:57 of the second round of a scheduled six-round super middleweight bout.

Also, Javier Martinez, an elite amateur making his pro debut, outboxed Ryan Burrs (2-2, 0 KOs) to win a shutout decision in a four-round super middleweight fight. And, in a six-round lightweight bout, Ruben Cervera (12-2, 10 KOs) defeated Clay Burns (9-9-2, 4 KOs) by a unanimous decision.
