Glamorgan 196 for 4 (Lloyd 56, Selman 78) beat Worcestershire 190 for 3 (Rutherford 100, van der Gugten 3-28) by six wickets
Dan Douthwaite powered Glamorgan to a six-wicket victory with a last-over six-hitting blitz against Worcestershire Rapids seamer Pat Brown in a T20 Blast dead rubber at New Road.
Douthwaite smashed three of the opening four balls from the England T20I bowler over the ropes to see his side to their 191 victory target with two balls to spare, ending with 23 not out from six balls.
His hitting upstaged a splendid century by Worcestershire opener Hamish Rutherford in the final game of his third spell with the county.
The New Zealand batsman hit four sixes and 11 fours in making exactly 100 from 62 balls in a brilliant display of hitting. It was the second T20 ton of his career and fell just short of his career-best 106 for Otago against Central Districts at New Plymouth four years ago.
Rutherford received excellent support from Jake Libby in a dazzling second wicket partnership of 101 in nine overs as the Rapids posted an impressive 190 for 3.
Glamorgan openers Nick Selman and David Lloyd gave their side a perfect platform in reply with a stand of 120 in 13 overs and then Douthwaite took centre stage.
Brown ended with figures of 2 for 62 from 3.4 overs - the most runs conceded by a Rapids player in a T20 innings.
