HOUSTON (AP) _ Kenny ''Machine Gun'' Mitchell upset Jose ''Gaby'' Canizales Friday night to win the U.S. Boxing Association bantamweight title.

Both fighters weighed in at 117 pounds. Canizales, 39-5, from Laredo, won the USBA title in November in Atlantic City from Louis Curtis. Mitchell was ranked seventh by the USBA coming into the fight.

Mitchell, 16-7-3, recorded a split decision, winning 114-111, 114-113, with one judge giving Canizales a 114-112 edge.

Mitchell, from Brooklyn, N.Y., appeared to gain confidence after the early rounds.

''I found out he couldn't punch when he hit me with a body punch, and it didn't hurt me in the first round,'' Mitchell said. ''I knew then I could out box him.''

McCall, 13-2-1, weighed in at 191 pounds, and was knocked down three times during the fight. Casimier, 14-3, weighed 189.

In a junior middleweight bout, Jim Harris, 8-3-2, of Conroe, Texas, defeated Ty Horne, 15-5, of LaPorte, Texas. Harris was a last minute substitute for Oscar Pena, of Laredo, Texas, who did not show.

In other action Anthony Stephens, 4-0, of Shreveport, La., stopped Raymond Chavez, 6-1, of LaPorte, with a second-round TKO in a junior welterweight bout, and Mike Sacchetti, 15-4, of Fairmont, W.Va., defeated Darryl Robinson, 8-2, of Houston by a split decision in a six-round middleweight contest.
