England Lions spinner Simon Kerrigan enhanced his growing reputation with a second seven-wicket haul in five days as Lancashire hit back strongly on day two of their LV= County Championship match with Glamorgan at Emirates Old Trafford.
The 24-year-old propelled his side to the top of the Division Two table with 7-63 in the second innings of the win over Northamptonshire at Wantage Road last week.
And as Glamorgan lost their last six wickets for 66 to slip to 474 all out, he became only the third Red Rose spinner to take seven-fors in successive innings since 1960 and the first since Gary Keedy in 2004.
He finished with 7-162 from 49.1 overs having taken his first two during the opening day.
Lancashire then made a strong start to their first innings by reaching the close at 93 without loss from 40 overs thanks to Karl Brown and Luis Reece, who will begin day three unbeaten on 48 and 42 respectively.
Kerrigan's haul included Murray Goodwin for a superb 194 off 354 balls, an innings spanning seven hours and 40 minutes.
The slow left-armer is now the leading spinner in either division in terms of wickets taken with 39.
Goodwin was excellent when compiling his highest score since May 2011, 274 for Sussex against Yorkshire.
He hit 21 boundaries but fell caught at square-leg off Kerrigan trying to pull his 22nd, leaving Glamorgan at 448 for eight.
The first Glamorgan wicket to fall in the day was Jim Allenby for 92 when he was trapped lbw by Glen Chapple to end a 155-run stand for the fourth wicket with Goodwin.
Kerrigan then had Mark Wallace caught at slip, Nathan McCullum at mid-on, Graham Wagg at short-leg, Goodwin at square-leg and Dean Cosker trapped lbw.
Chapple wrapped up the innings when had John Glover caught and bowled.
While Glamorgan still hold the upper hand in the contest, they could yet face a tricky end to the contest on a deteriorating wicket should Lancashire bat past their first-innings score.
Brown and Reece, although watchful, looked in little trouble during their 40 overs at the crease.
They are Lancashire's fifth different opening pair in championship cricket this summer and none of the other four have returned a partnership of three figures.
