Jacques Rudolph believes Glamorgan have found their killer instinct after the county made it three wins in four one-day matches.

The South African was full of praise for his team after their convincing 52-run victory over reigning champions Gloucestershire in the Royal London One Day Cup at the Swalec Stadium on Monday.

Rudolph – who has been short of form – hit 53 for his first half-century of the season and the captain was backed up by Will Bragg, who hit 75.

Chasing 290 to win, the visitors were eventually restricted to 237 all out, despite Michael Klinger’s 52 and some late stroke play from Benny Howell (77).

Rudolph said: “We were quite clinical in the way we went about our business. William Bragg batted outstandingly but we were 15-20 runs short of where we could have been.

“I just wanted to spend some time in the middle. That’s important when you’re not performing as well as you’d like and I was fortunate to bat with Braggy who’s in very good touch.

“Our bowlers were very good. Colin Ingram bowled exceptionally, as well as Timm van der Gugten.

“At the moment we’ve got some good momentum in white-ball cricket. If that can continue for the rest of the week I’ll be a happy captain.”

Despite half-centuries from Michael Klinger and top-scorer Benny Howell (77), Gloucestershire were always behind the run-rate and lost wickets at regular intervals on their way to 237 all out.

Glamorgan, having been put in by Klinger, had been in a position during their 50 overs to have scored in excess of 300 as Rudolph and Bragg laid the foundation with a second-wicket stand of 122 in 20.2 overs.

They suffered a mini collapse, however, losing four wickets for 23 before settling on a solid total which required Gloucestershire to score at almost six runs an over.

At first they made inroads but with 10 overs remaining they required 105 to win, with Tom Smith and Howell having shared a useful stand of 66.

From there, Craig Meschede uprooted Smith’s off-stump with his third ball and Howell battled until the end before he was the last man out – caught on the extra-cover boundary – having hit seven fours and a six in 67 deliveries.

Gloucestershire captain Michael Klinger said: “We got out-worked because they out-fielded us and bowled really well to their field.

“Last year we won seven out of eight. There’s no reason why we can’t win five out of six now but we need to do the little things a bit better, particularly in the field.”
