|Royal London One-Day Cup, Scarborough|
|Yorkshire 175 (49.5 overs): Leaning 40, Rhodes 37; Trego 4-29|
|Somerset 178-4 (38.1 overs): Abell 80; Fisher 2-29|
|Somerset won by six wickets|
Yorkshire wasted a chance to clinch their place in the One-Day Cup quarter-finals as they lost by six wickets to Somerset at Scarborough.
They were 17-3 and later 108-9, but last-wicket pair Karl Carver (35 not out) and Matthew Fisher (34) added 67 before they were all out for 175.
Peter Trego took 4-29 for the visitors, who were made to work for their win by an accurate Yorkshire attack.
Opener Tom Abell made 80 off 112 balls as they reached 178-4 in the 39th over.
|Yorkshire's record 10th-wicket partnership in List A cricket is 80 by David Bairstow and Mark Johnson against Derbyshire in the 1981 B&H Cup (55 overs a side)|
|Their previous 10th-wicket record against Somerset was 39 by John Blain and Deon Kruis in the National League in 2005 (45 overs)|
The 21-year-old struck 10 fours in his highest one-day score for the county, but was caught behind off Will Rhodes shortly before the end, with Jim Allenby hitting the winning boundary.
Earlier, Craig Overton produced a superb new-ball spell of 2-8 from eight overs and there were two wickets for Josh Davey as well as Yorkshire made a calamitous start to the game.
Jack Leaning (40) and Rhodes (37) added 70, but the only other partnership of note was between 19-year-old Carver and 17-year-old Fisher, who set a new Yorkshire 10th-wicket record for a limited-overs game against Somerset.
Fisher later took 2-29, but it was all in vain as Somerset knocked off the runs with 71 balls to spare.
Yorkshire, however, will reach the knockout phase if they beat Northants in their final group game at Headingley on 18 August, while Somerset need to win their last two games and hope other results go their way.
Yorkshire captain Alex Lees:
"We are gutted we've lost. The manner we've lost was disappointing. We have played some excellent one-day cricket of late.
"We are well aware as a team that we are going to lose games.
"It's not always going to be your day, but we are going to back what we've done in one-day cricket so far and look forward to the next game."
Somerset director of cricket Matt Maynard:
"We've been threatening that. We have done some good stuff in this competition, but we just haven't been able to get over the line.
"I thought we stuck at it brilliantly with the ball. We got some luck, which you always need. At times that's been missing this summer.
"Craig Overton and Josh Davey getting those early wickets helped a great deal. I thought we were brilliant in the field, and it was a very polished innings by Tom Abell in the run-chase."
