Australian seamer Michael Hogan recorded figures of 6-65 as Glamorgan claimed a useful 220-run lead on day two of their LV= County Championship Division Two match against Kent at the SWALEC Stadium.
That advantage could prove to be a decisive one in a low-scoring game, after another 12 wickets fell following the 15 that tumbled yesterday.
Glamorgan ended on 237 for seven, opener Gareth Rees top-scoring with 52, having bowled out Kent for 175.
The visitors had resumed on 102 for five, still trailing by 56 runs. Daniel Bell-Drummond reached a half-century from 111 balls but, with the visitors on 136 for five, tall seamer Mike Reed bowled Adam Riley with a full-length delivery.
Hogan grabbed the important scalp of Bell-Drummond for 78, trapping him leg-before, and two balls later the Australian bowled Mark Davies off his pad.
Charlie Shreck edged behind in the next over to end Kent's innings and give Hogan his sixth wicket, before Rees negotiated the solitary over remaining before lunch.
In the afternoon, Glamorgan lost a couple of quick wickets as Will Bragg and Murray Goodwin departed to Davies in the space of three balls to leave the hosts 15 for two inside seven overs.
But Rees and Chris Cooke added 67 for the third wicket, helped by the former straight-driving Riley for four and six.
However, the young off-spinner responded in his next set of six by having Cooke caught at short leg by Bell-Drummond.
Glamorgan reached the 100 mark in the 32nd over and Rees went on to complete a half-century as they led by 104 at tea.
But he perished straight after the interval, edging Calum Haggett behind, after which the bowler trapped Ben Wright lbw with the total on 155.
Riley had Jim Allenby caught at deep backward square, miscuing a sweep on 29. And while Ruaidhri Smith and Mark Wallace guided Glamorgan to 200, the latter soon edged Shreck behind to depart for 29.
But any Kent hopes of further scalps were denied by Smith and Dean Cosker, who safely navigated the final eight overs of the day between them to take Glamorgan’s lead past the 200 mark.
