Sussex took control on day one of their LV County Championship against Glamorgan in Cardiff.

The Sharks finished the day on 99-0 with Aaron Thomason (52 not out) reaching his half century before the close of play.

Tom Haines (43 not out) continued his impressive start to the season with the bat.

Skipper Ben Brown won the toss and decided that they would have a bowl first.

That decision paid off just four ball into the innings with Ollie Robinson trapping Nick Selman lbw for a duck.

Robinson picked up his second not long after as he trapped Andrew Balbrine lbw for four.

Billy Root, who is the younger brother of England Skipper Joe Root, was next to go as like the two previous wickets he was trapped lbw but by Henry Crocombe, leaving the hosts 23 for 3 in the eighth over.

Glamorgan were dug out of trouble by David Lloyd and Kiran Carlson, who put on a partnership of 110 for the fourth wicket, before Lloyd was caught by George Garton off the bowling of Crocombe for 84 from 99 balls.

Skipper Chris Cooke built the third highest partnership of the innings with Carlson before he became Robinson’s third victim of the innings as he was trapped lbw.

Robinson then picked up the wicket of Callum Taylor a few overs later, as he was caught by Stiaan Van Zyl, to leave the England prospect to finish the innings with figures of 4 for 50.

Dan Douthwaite and Carlson then put on a massive partnership of 111 for the seventh wickets, before Stuart Meaker dismissed Douthwaite for 36 after he picked out Tom Clark.

The hosts lost their last three wickets for 19 runs as they were all out for 285 within 75 overs.

Carlson was the only man left standing as he hit his first century in two years, with his unbeaten 127 coming off 182 balls.

It meant Glamorgan fell short of the third batting point they should have earned.

Carson took three for 14 wickets in his seven overs as the tail subsided tamely while teenage seamer Crocombe, part of a youthful Sussex line-up, claimed two victims to finish with figures of two for 44.

The visitors came out to bat and got off to a flying start thanks to their openers.

Thomason hit 10 fours as he finished the day on 52 off just 79 balls.

Haines, who had hit 181 runs in their draw against Lancashire at Old Trafford last week, continued his fine form with the bat as he finished 43 not out.

It means the Sharks closed the day trailing Glamorgan by 186 runs with all ten wickets in hand.

However, Robinson felt Sussex could have been in a more commanding position.

He said: “It was good to get three early wickets.

“But we let it slip a little bit in the second hour but I thought the rest of the day we were on top.

“We pulled it back a little bit after lunch and Jack Carson finished off their innings with three quick wickets which was very handy.”

The seamer also revealed why the Sharks decided to bowl first after winning the toss.

He said: “We just thought it had live grass on it and the best time to bowl would be the first day.

“Kiran Carlson played well and stopped us from bowling them out for 200.

“Overall we have had a good day.”
