Leicestershire 96 (van der Gugten 5-52) and 283 (Dexter 73, Robson 72, van der Gugten 4-81) beat Glamorgan 199 (Carlson 74*, McKay 3-12) and 154 (Bragg 65, Shreck 4-33) by 26 runs
Glamorgan lost their last six wickets for just ten runs as Leicestershire pulled off an incredible victory in their Division Two Specsavers County Championship match at Grace Road.
Resuming on 11 for 1 and needing 181 to win, the visitors were wobbling when they lost two early wickets. Left-arm seamer Dieter Klein was the man responsible, swinging the ball at pace to take the edge of Jacques Rudolph's bat before knocking Owen Morgan's middle stump out of the ground to leave Glamorgan on 36 for 3.
It should have been four, but Leicestershire dropped Will Bragg off his first ball, delivered by Klein and edged between wicketkeeper Ned Eckersley and first slip Paul Horton. Horton got his fingers to the ball, but couldn't hang on, and it proved an expensive miss as Bragg and Aneurin Donald added 53 for the fourth wicket.
Donald, who began his innings needing to score 40 to reach 1000 Championship runs for the season, was on 23 when he pushed tentatively at a Charlie Shreck outswinger and edged to second slip, but Bragg continued to make Leicestershire pay, going on to a half-century as Glamorgan lunched just 45 runs short of what would be their fourth Championship win of the season.
Few could have predicted what would happen next. Clint McKay, charging in from the Bennett End seamed consecutive deliveries back in to win leg-before decisions against Kiran Carlson and then - perhaps a touch fortunately - Craig Meschede.
In the following over, Mark Wallace pushed forward to Shreck and edged to Eckersley and Timm van der Gugten, deep in his crease, survived only one delivery before being pinned leg before by the veteran Cornishman.
Michael Hogan drove airily and edged McKay behind the wicket, and then a despairing and desperate Bragg, who had been watching in disbelief at the other end, lofted Shreck high towards the cover boundary where Harry Dearden, making his home debut, held the calmest of catches to seal the most unlikeliest of wins.
