Junior lightweight prospect Joel Diaz Jr. handed Tyler Asselstine his second pro loss with a unanimous decision in the main event of Friday's ShoBox: The New Generation at Foxwoods Casino in Mashantucket, Conn.. Junior middleweight prospect Frank Galarza outpointed Sebastien Bouchard in the co-feature.

Diaz (16-0, 12 knockouts) controlled the tempo of the fight against Asselstine (14-2, 7 KOs), winning 97-92 on the cards of all three judges.

"It was a learning experience. I wish I got hit less," said the 22-year-old Diaz, who is trained by Abel Sanchez and suffered the first cut of his career from an accidental clash of heads in the eighth round.

"It was great to get the rounds in and go the full 10 for the first time. We're going to go back to the gym and look at our mistakes. I could have thrown more punches, but I’m still undefeated. He was a hell of a fighter, but only the strong survive, and that was us today."

Asselstine was fighting for the first time at 130 pounds.

"I’m too small for 130, but I'm happy I took the fight because it was a great opportunity," said Asselstine, who is 27. "I fought a guy with 12 knockouts in 15 fights and took everything he had. He's strong, but I'm a 126, 122-type fighter. I loved the opportunity because it showed me what I can take."

In the opening bout of the telecast, the 28-year-old Garlarza (14-0-2, 9 knockouts) failed to earn his fifth straight knockout against Bouchard (8-1, 2 KOs), even as he won by scores of 77-74 (twice) and 78-73. Galarza used a sustained strategy of movement behind a solid jab and body work to keep Bouchard at bay.

"We got the job done. We showed our boxing ability, we showed our punching power," said Galarza. "We tried not to waste any punches. We had a game plan and we executed the plan. He was a tough guy, but we landed with ease."

After repeated warnings, Galarza was deducted one point for a low blow in the eighth, a penalty that ultimately didn't have an impact in the final results.

"We won maybe three of the eight rounds, plus the point deduction in the eighth," said Bouchard. "So it should have been a draw. The last judge wasn’t watching the fight. He was hard to hit, and my right was hard to place because of his style."

Galarza has gone 6-0-1 with five knockouts in his past seven fights. In January, Galarza scored a second-round knockout over previously unbeaten John Thompson. Prior to Bouchard, Galarza had last been in action for April's second-round knockout of Franklin Gonzalez entering the bout with Bouchard.
