County Championship: Glamorgan's Salter has Northants in a spin

Pembrokeshire-born Andrew Salter made his Glamorgan debut in 2013

Glamorgan's Championship match against Northamptonshire remains evenly poised after rain again wiped out half of the second day.

Glamorgan will resume on 52-2 in reply to the visitors' 215 all out.

Spinner Andrew Salter took a career-best 4-18 as Northants' lower-order subsided from 181-4.

They were a man short with all-rounder Gareth Berg suffering an ankle injury in the warm-up which will see him miss the rest of the game.

Berg, 40, is also set to sit out the One-Day Cup campaign.

After a 30-minute delay in the morning, Charlie Thurston (48) and Saif Zaib (50) were sailing along in a stand of 87 with Northants well set for a substantial total.

But Thurston slashed Michael Hogan to gully after a season's best score, allowing Salter to strike three times in quick succession as Zaib drove to cover after seeming untroubled in his 95-ball knock.

Jack White slogged a pair of boundaries to take his side past 200 before holing out off Salter for 10, leaving keeper Harry Gouldstone not out with a patient 17 in his maiden innings.

The visitors' depleted attack still managed to dismiss Glamorgan's openers cheaply, with Ben Sanderson having Joe Cooke caught at slip by captain Ricardo Vasconcelos for 16, while David Lloyd edged Luke Procter to the same fielder for 13.

Marnus Labuschagne was on 17 not out when a downpour just after tea ended the day's action.

Glamorgan's Andrew Salter told BBC Sport Wales:

"It was a good day in the office, really enjoyed myself because as a bowler you always appreciate the good days where those chances go to hand, delighted with the day.

"The wicket is a good one and I just wanted to keep things nice and tight, and see if there was some assistance since part of my role is building pressure, so it was ideal that when they did take those chances it paid off in my favour

"It's been a shame the weather has interrupted things later on in the day though the groundsmen did an excellent job for us to start so early with heavy rain overnight.

"We're going to try to bat big and put some pressure on them for their second innings, but we're in a good space."

Northants coach David Ripley told BBC Radio Northampton:

"It's not great news about Gareth Berg, he's had a scan and he's on crutches, so he'll be taking no part in this game and I'll be surprised if we see him in the 50-overs competition.

"There was no-one near him, he just turned and fell over on his ankle. Hopefully he'll be back for some Championship cricket towards the end of the season

"Luke Procter is on the team-sheet to bowl and hasn't had the opportunities he would have liked so we put him out as one of four seamers, now he's become one of three and he is a skilful, skiddy bowler, and hopefully (spinner) Simon Kerrigan might come into the game more on a wearing pitch.

"The first hour of both days we've been really good, but we've kind of lobbed a few wickets away, we've blunted the seamers then handed over some soft ones with five of our nine dismissals caught in the (inner fielding) ring."
