Ruaidhri Smith produced career-best bowling figures of 4/75 on day three of Glamorgan\'s Specsavers County Championship match against Northants.
The Welsh county however saw the visitors post a lead of 433 after Ricardo Vasconcelos (79) and Steven Crook (73) dug in during the afternoon session despite losing five early wickets in the morning.
"It was a slightly difficult day for us as a team, we all put in the hard yards but it didn't come off at times though I was pleased to pick up a few wickets.
"It's getting there, I'm bowling more and more overs and hopefully it's going in the right direction.
"We'll go again and hopefully get something out of it, it's a lot of runs but we'll set manageable tasks throughout the day. Usman's been fantastic for us, we couldn't have asked any more, and it was unfortunate for him to get out the way he did."
