YORKSHIRE’S very own TomTom system drove Warwickshire mad on day one of their season-ending Specsavers County Championship fixture at Edgbaston, with Messrs Kohler-Cadmore and Loten starring in a dominant rain-affected batting day.

Kohler-Cadmore posted his ninth career first-class hundred, but his first opening the batting, to underpin a close of play 261-2 from 64 overs.

He finished unbeaten on 165 from 175 balls in his 100th first-class innings, four runs short of his best Championship score - achieved as a Worcestershire player in 2016.

York-born Loten, the club’s tall 20-year-old Academy captain making his first-class debut, joined his fellow Tom to advance the score from 77-1 either side of lunch with a polished 58 from 155 balls.

Unfortunately, he was out to the last ball of the afternoon - it also proved to be the last ball of the day, with rain arriving during the tea break. There was no play beyond 3.15pm.

Kohler-Cadmore was elevated to open against the Bears in place of teenager Matthew Revis, who debuted in last week’s defeat against Kent at Emerald Headingley.

Loten replaced Revis in the team, but Kohler-Cadmore faced the new ball alongside Adam Lyth in a batting reshuffle and put on 77 with his limited overs opening partner.

Kohler-Cadmore and Loten then shared 184 inside 47 overs.

After Steve Patterson won the toss and elected to bat, Kohler-Cadmore confidently set about posting his second Championship hundred of the season for a White Rose side desperate to make up for two heavy defeats in the last fortnight.

He was particularly dominant down the ground on a good batting surface and brought up three figures off 113 balls, with 16 fours and a six, in the early stages of the afternoon, by which stage the score was 151-1 in the 39th over.

This pitch, used for all three games during Saturday’s Vitality Blast Finals Day, is an excellent one for batting.

Lyth (26) and Kohler-Cadmore both hit early sixes, with the latter’s lofted over long-off against the spin of Bears captain Jeetan Patel.

Loten left the ball superbly and also played confidently through mid-wicket.

He has come into the side having been one to watch for some time.

He has scored three fifties for the Academy and second team combined this summer, but his availability has been punctuated by toe and finger injuries.

But his fourth, brought up off 142 balls with seven fours shortly before tea, was undoubtedly his most important and has laid down a marker ahead of next season.

Lyth was the first wicket to fall when he edged Craig Miles to Sam Hain at second slip midway through the morning, with his 26 taking him beyond the 800-run mark in Championship cricket for the summer, something Kohler-Cadmore later achieved as well.

Loten later fell with what turned out to be the last ball of the day when he edged off-spinner Alex Thomson to Will Rhodes at slip, although umpires Graham Lloyd and Russell Warren had to convene to rule out initial thoughts of a bump ball.

After back-to-back defeats against Somerset and Kent, the latter by a record 433-run margin at Emerald Headingley last week, this was the perfect start to the game for the White Rose.

Had the final session not been wiped out here, Yorkshire could have even reached 400 in the day, something which Kent did on day one last Monday.

Play was called off for the day at 4.30pm.
