Rattlers quarterback Nick Davila threw for 373 yards and connected with Rod Windsor for five of his eight touchdown passes. Windsor finished with six receptions for 147 yards and Maurice Purify had seven catches for 134 yards and three scores.
The Rattlers set an AFL record with the 14-0 start and the two-time defending league champions have now won a record 18 in a row.
Aaron Garcia led the KISS (3-10) by passing for 315 yards and four touchdowns. Donovan Morgan caught three touchdown passes among his 14 receptions and finished with 159 yards receiving. Kenny Guiton came off the bench with the game out of hand to pass for two touchdowns.
The KISS had pulled to within 21-20 when Garcia connected with Morgan on a 27-yard scoring strike in the second quarter. The Rattlers reeled off 28 unanswered points, though, to open leads of 42-20 at halftime and 49-20 early in the third quarter.
L.A. broke through for another score on an 11-yard connection from Garcia to Morgan to cut the deficit to 49-27, but that would be as close as the KISS would get the rest of the way. Davila hit Windsor on scoring passes of 45 and 43 yards late the third quarter to put the game out of reach at 62-27.
