Friends Life t20, Lord's
Sussex 165-8 (20.0 ovs) beat Middlesex 116 (18.5 ovs) by 49 runs
Goodwin hit 48 off 33 balls before being bowled by Ryan McLaren
Murray Goodwin hit 48 runs as Sussex gained revenge over Middlesex with a 49-run victory to move to the top of the Friends Life t20 South Group.
Sussex reached 165-8 before dismissing the hosts for just 116 despite Scott Newman's best efforts, as he made 44.
Left-arm seamer Chris Liddle (4-20) took the last three wickets to ensure the visitors moved above Hampshire.
Middlesex's only win in this season's competition was a five-wicket victory at Hove on 10 June.
Sussex slumped to 2-2 in the second over before a 69-run stand off 39 balls from Luke Wright (34) and Lou Vincent (44) revived their innings.
Liddle may have missed out on a hat-trick but he still swiftly finished off the hosts, claiming the last three wickets in just five balls.
Middlesex batsman Chris Rodgers was unable to bat after suffering a hand injury.
Middlesex captain Neil Dexter told BBC Sport:
"In the field we had them a few wickets down with not many runs but didn't capitalise on that.
"We were in a good position and then Vincent and Goodwin played good innings.
"At the end of the day they outplayed us in all departments. "
