CHRIS TREMLETT produced a career-best performance for the second time in six days - then set his sights on an England one-day call-up.

Tremlett took 6 for 44, including 5 for 9 in 26 balls, as Hampshire had the better of the first day of their championship match against Sussex.

It followed his career-best innings of 64 that helped defeat Gloucestershire at the Rose Bowl last week.

Now the 23-year-old is determined to maintain his blistering start to the season - and win a place in England's one-day squad.

He said: "Realistically, I can't see myself playing Test matches this summer, my goal is to force myself into the one-day squad first.

"If I keep plugging away hopefully the selectors will notice me soon. I back myself to go to the next level and if I keep bowling well, am tighter with my economy rate and continue to score runs, I've definitely got a good chance."

Tremlett's heroics helped Hampshire take the last seven Sussex wickets for just 18 runs in 11 overs.

He had started the day brightly by dismissing Ian Ward in his third over with the new ball.

But then Murray Goodwin and Michael Yardy looked to have made it Sussex's day with a stand of 172 for the third wicket, before a stunning Shane Warne catch provided the catalyst for another brave Hampshire fightback.

The Hampshire captain, who used SEVEN bowlers before lunch, took the crucial wicket of opposite number Chris Adams in spectacular fashion - and it changed the balance of power in an instant.

Warne dived low to his left to catch Adams one-handed and the last six wickets fell rapidly.

Warne added the wicket of England hopeful Matthew Prior, who was trapped leg before as he attempted to sweep, in his next over.

And then Tremlett showed why Warne is tipping him to play during this summer's Ashes series - by wiping out the Sussex tail in spectacular fashion.

His devastating five-over spell began with the dismissal of Yardy, who is fast gaining a reputation as one of the most improved players on the county circuit.

Yardy's third hundred in as many championship games made him the first Sussex player to score three first class hundreds in successive matches since Tony Cottey in 2003, following the tons he scored against Surrey at the end of last season, and the beginning of this.

The Hastings-based left hander hit 14 fours in his 104.

But, after he was caught behind, 6ft 7in Tremlett came across little resistance on the way to his fourth haul of five wickets or more in his 44-game first class career - and his first since taking 6 for 51 in the follow-on win against Glamorgan two seasons ago.

This was also Tremlett's best return away from the Rose Bowl since taking 5 for 57 against Lancashire at Old Trafford in August 2002.

Sussex's tail had no answer to his pace and steep bounce.

But it was Billy Taylor, on his return to Hove, who broke the dominant partnership between Yardy and Goodwin, when he bowled the latter for a 121-ball 87.

Taylor had been warmly applauded by the Sussex members when he came on to bowl against his former employers, less than two years after winning the county championship in the last of his five seasons at Hove.

But before limping off for treatment on a tight hamstring Taylor ended a crowd-pleasing Goodwin innings. It included a straight six off Kevin Pietersen's occasional off-spin, and a pulled six against fellow Western Australia man Sean Ervine.

In reply, Hampshire lost Michael Brown early on before progressing to 67 for 1 at stumps.

Simon Katich (29*) was dropped at short leg by Richard Montgomerie, having scored eight, but two balls later he responded by smashing James Kirtley over mid-wicket for six as he and Jimmy Adams (30*) added 56 runs for the second wicket before the close.
