Kent 10 for 0 trail Glamorgan 351 (Wagg 83, Meschede 78, Claydon 5-106) by 341 runs
Graham Wagg and Craig Meschede rescued Glamorgan with a partnership of 160 in 33 overs for the seventh wicket after Kent's seamers had threatened to take control on the second day in Cardiff.
Mitchell Claydon helped reduce Glamorgan to 137 for 6 but the efforts of Wagg and Meschede, who made 83 and 78 respectively, helped their side to a competitive first-innings total of 351 on a fresh pitch that encouraged the seamers. Kent had six overs to face at the end of the day and ended on 10 for nought.
Wagg and Meschede's partnership was a record for the seventh wicket against Kent, exceeding the 107 previously set by Eifion Jones and Arthur Francis at Canterbury in 1982.
After the morning session had been lost to rain - with 104.5 overs now lost over two days - Claydon soon made inroads by taking 3 for 17 in 28 balls, including Will Bragg and Chris Cooke, who had added 88 for the third wicket. Bragg chased a wide one, which he nicked to the wicketkeeper Adam Rouse, before Cooke was surprised by a lifter and was taken at third slip.
Aneurin Donald was also out to a loose stroke, and when David Lloyd's enterprising innings ended with Calum Haggett's second ball of the day, Kent would have been pleased by their bowlers' efforts.
The seventh-wicket pair began cautiously but then produced an array of attacking strokes, with Wagg reaching 50 by taking 10 runs from James Tredwell's only over of the innings.
Meschede was dropped twice on 43 and 46 before reaching his half-century. Wagg was 17 runs away from his second century against Kent this season when he edged Claydon to second slip, before Meschede, whose only other fifty this season was also against Kent, was dismissed by Haggett, who took his third wicket when Timm Van Der Gugten became wicketkeeper Rouse's fourth victim.
A rousing partnership of 33 between Andrew Salter and Michael Hogan enabled Glamorgan to gain a fourth batting point by passing 350, while Claydon was rewarded for his wholehearted effort by taking 5 for 106.
