Gloucestershire 299 for 4 (O. Price 116*, Tector 86, Taylor 51*) beat Derbyshire 298 for 9 (Haider Ali 82, Reece 50, van Meekeren 4-66) by six wickets

Signed for just one game, 23-year-old Ireland international Tector made the most of his only opportunity to impress a substantial Festival audience, scoring a startling 86 from 69 balls, while Taylor finished unbeaten on 51.

Pakistan batter Haider Ali had earlier top-scored with 82 and opener Luis Reece hit 50 as Derbyshire posted 298 for 9 after losing the toss, Paul van Meekeren claiming 4 for 66 and Zaman Akhter 3 for 56 to enable Gloucestershire to keep a lid on things.

Required to score at 5.98 an over, Gloucestershire made a poor start to their reply, Sam Connors sweeping up openers Ben Charlesworth and Chris Dent in the space of four deliveries from the College Lawn End to reduce the home side to 16 for 2 in the third over.

Fresh from representing Ireland against Scotland in a T20 international in Edinburgh three days earlier, Tector took a challenging situation firmly in his stride, scoring at a run-a-ball from the outset to set a defiant tone.

Taking advantage of a short boundary at the famous old College Ground, the Dubliner produced an innings of controlled aggression to raise 50 from 52 balls before tucking into Mark Watt's slow left arm as he pressed on the accelerator.

He and Price staged a 100 partnership in 92 balls and, by the time his electrifying innings was terminated by David Lloyd, who had him held at mid-on in the 23rd over, Tector had plundered eight fours and four sixes and given Gloucestershire the upper hand.

With a further 141 required at 5.2 an over, Price took it upon himself to see the job through, going to his hundred from 101 balls, a landmark that elicited a standing ovation from all who witnessed it. James Bracey was bowled by Alex Thomson for 23, but Taylor remained at large for long enough to raise a 45-ball 50 and confirm his return to form.

These two were still there at the end, Price having faced 115 deliveries and amassed 13 fours to continue his outstanding run of form at the College Ground.

Put in to bat, Derbyshire were afforded a super-charged start by openers Reece and Harry Came, who mustered a blaze of boundaries in posting a progressive stand of 71 in 11.1 overs. Josh Shaw and Ajeet Singh Dale proved expensive with the new ball, the visitors rushing to 50 from 51 balls.

Severe on anything short or wide, the openers helped themselves to 12 fours and a six, scoring 54 runs in boundaries to take the wind out of Gloucestershire sails. With runs coming too easily, the home side introduced slow left armer Zafar Gohar and experienced paceman van Meekeren in an attempt to apply the brakes.

Came had raised 40 from 32 balls and had his eyes trained firmly on a half century when he was bowled by van Meekeren, who then made good the breakthrough by persuading Lloyd to chip to mid-wicket in an incisive five-over spell of 2 got 28.

Reece mustered further belligerence in scoring 50 from 58 balls, with eight fours and a six, only to pull Zafar to deep backward square as the Pakistani produced a wicket maiden to reduce the visitors to 101-3 in the nineteenth over.

Required to rebuild the innings, Haider and Brooke Guest advanced the score to 140 for 3 at the halfway stage, the 50 partnership occupying 53 balls. These two plundered 29 off three overs of off spin from Ollie Price to give their alliance momentum, Haider collecting a half-century in the process. Content to play a supporting role, Guest contributed a 48-ball 43 in a stand of 104 that served to put Derbyshire back on track.

It was Derbyshire's first hundred stand in any one-day match played at Cheltenham and Gloucestershire were sorely in need of relief by the time Guest pulled the returning van Meekeren to mid-wicket and Zaman Akhter removed Anuj Dal. But while Haider remained at large, anything still seemed possible for the East Midlands county.

Having straight-driven and pulled Akhter for four and six in successive balls, the Pakistani international allowed complacency to creep in, chipping the same bowler to mid-wicket and departing for 80. He had faced 65 balls and accrued eight fours and three sixes and, with him, went Derbyshire's best chance to posting a truly imposing total.

Tom Wood struck 28 and Watt 22 not out as the final 10 overs yielded 69 runs, but there was a feeling that the visitors could and should have done better. For their part, Gloucestershire were indebted to van Meekeren and Zafar, who returned figures of 4 for 66 and 1 for 30 respectively, the latter sending down a remarkable 40 dot balls in his 10 overs.
