Richard Levi hit a quickfire century to lead Northamptonshire to a comfortable 17-run victory over Gloucestershire in the Friends Life t20 at Cheltenham.
The powerful South African blasted 110 not out off 62 balls, with 15 fours and four sixes, as his side ran up 206-3 after losing the toss. Alex Wakely contributed 35 and Steven Crook a rapid 27 not out.
After taking a few deliveries to gauge the pitch, Levi cut loose with a series of meaty cuts to go with his trademark leg-side shots. He lost opening partner Kyle Coetzer to the first ball of the fifth over, caught by Gidman at mid-wicket off Tom Smith for 15 with the total on 31.
It was 49-1 at the end of the six overs of power play and with two runs added, Cameron White, on 10, was caught on the deep mid-wicket boundary by Dan Christian pulling a delivery from Benny Howell.
Wakely then helped Levi add 89 for the third wicket in 8.4 overs, hitting two straight sixes in an over off the left-arm spin of Chris Dent in his 24-ball innings, which helped take the score to 140-3.
The Northants skipper was annoyed with himself for giving a catch to long-off in the 16th over, giving Howell a second wicket. But there was no dislodging Levi, who moved to his century with his fourth six, hammered over mid-wicker off Dent in the 19th over.
Crook joined the party with two sixes of his own, one of them bringing up the 200 in the final over, bowled by David Payne. Left-arm spinner Smith escaped the carnage with creditable figures of 1-25 from his four overs.
In reply, Gloucestershire plunged to 21-3 as David Willey (4-32) claimed 3-5 from his first two overs. Alex Gidman, who hit 49 off 19 balls, and Ian Cockbain (60) ensured respectability, but they were never seriously in the hunt and finished on on 189-6.
The result means Northants join Glamorgan on eight points from five games at the top of the Midlands/Wales/West Division, while Gloucestershire can forget the quarter-finals, having lost four of their first five matches.
