The U.S. Open is going into its third day, and there are already a few upsets on the board. Pablo Matheu defeated Tony Robles and David Grossman beat Rodney Morris.

But many favorites are still undefeated after two rounds, including Efren Reyes and John Schmidt (who play each other today), as well as former U.S. Open Champs Johnny Archer and Francisco Bustamante and defending champ Gabe Owen.
