Julio Cesar Chavez Jr. reached 20-0 with a fourth-round technical knockout of limited but very tough Ruben Galvan. Chavez hurt Galvan with head shots in the final ten seconds of the first round and wasted no time moving in for the kill. A left to the body almost ended the bout at the three-minute mark, but the bell gave Galvan a sixty-second rest. In the second, Galvan showed strong recuperative powers and landed an unexpected number of blows, but they were mostly arm punches that lacked any real power. In the fourth round, Chavez turned the heat back up and landed a combination that dropped Galvan to the canvas, practically underneath the bottom rope. Galvan got up and took a ferocious beating as referee Benji Estevez looked for an appropriate moment to stop the fight. Galvan was getting pummeled but didn't give Estevez an opening because he kept coming forward and continued throwing punches. At 2:22, his corner finally threw in the towel, marking the first time that Galvan, now 21-7-2 had ever been stopped. Galvan was angry with his corner for stopping the bout.  "He had a lot of heart," said the young Chavez, "and I was very proud to stop him."  Chavez's promoter, Top Rank is keeping their prize prospect busy, and he is already scheduled to get back in the ring on August 13 in Phoenix.
