Southampton stormed 5-1 ahead by the middle of the second quarter with goals by Cianan Mann (3), Jackson Mullins and Charles Roberts. After that, it was a case of Croydon chipping away at the lead; they cut the deficit to a single goal with an Andrew McAllister man-up goal in the final period but couldn't snatch a point.
Worthing, who beat Southampton 5-4 on day one, picked up their second win - 10-4 against Cheltenham Spartans - while Manchester Hawks eased through 12-5 against Cambridge.
