Glamorgan had much the better of day one of their LV= County Championship Division Two clash with Leicestershire, dismissing their visitors for 109 and then reaching 56 for one before the weather brought a premature close.
No Leicestershire player managed double figures until number six Niall O'Brien, whose 17 turned out to be their joint highest score of the innings alongside Anthony Ireland, as wickets tumbled at an alarming rate for the Foxes.
Tom Helm saw off two of Leicestershire's top three, finishing with figures of 2-9 from six overs, with Jim Allenby and Will Owen backing up his efforts with three wickets apiece, while returning Australian seamer Michael Hogan helped himself to 2-30.
The hosts won the toss - a feat their opponents have not achieved so far this term - and could hardly have made a better start when play belatedly got under way as Hogan, fresh from attending the birth of his second child in Perth, got rid of Greg Smith for a duck with just the second ball of the day.

Fellow opener Angus Robson followed suit soon after the first of several rain-enforced interruptions, trapped leg before by Helm for five.
And Helm was not done there, bowling Ned Eckersley for nine to leave the visitors reeling on 17 for three.
Josh Cobb contributed only four before becoming Owen's first victim from the bowler's second ball, caught at mid-off by Will Bragg, and captain Ramnaresh Sarwan did not fare much better before nicking to wicketkeeper Mark Wallace off Allenby for seven.
O'Brien and Rob Taylor brought a little respite when they shared the best partnership of the Leicestershire innings with a 28-run sixth-wicket stand, before both falling with the score on 62 - caught behind off Allenby and Hogan respectively.
Jigar Naik and Ireland hung around for eight overs before the latter was tempted into an ill-fated pull by Owen, who further added to his wicket haul by having Nathan Buck caught behind in his next set of six.
Naik and Charlie Shreck eked out a 19-run final-wicket stand to at least get Leicestershire into treble figures, but there will have been little celebration of that landmark at the tea interval.
Tom Lancefield made his county debut at the top of the Glamorgan order alongside Jacques Rudolph and, although he provided Leicestershire with their only moment of joy with the ball when he edged Taylor through to O'Brien before the showers again returned, it was very much the home team's day.
Rudolph will resume usefully set on 26 alongside Bragg, with Glamorgan hoping to build a healthy first-innings advantage.
