Glamorgan 318 and 53 for 0 lead Nottinghamshire 285 (Montgomery 80, Hameed 70, James 50, Hogan 4-47, Harris 4-65) by 86 runs

Michael Hogan and James Harris both took with four wickets as they ruined top-of-the-table Nottinghamshire's hopes of surpassing Glamorgan's modest opening day total of 318 in Division Two.

Having resumed on their overnight 19 for 0, Notts moved effortlessly to 233 for 3 and then 255 for 4 before losing their last six wickets for a mere 30 runs, trailing by 33 on first innings.

Glamorgan had 17 overs to face at the end of the second day and they successfully negotiated that test to end on 53 for 0 to take a very handy 86-run lead into the third day as skipper David Lloyd ended unbeaten on 21 and Eddie Byrom on 28.

Matthew Montgomery marked his County Championship debut for Notts with a superb catch on the first day at Sophia Gardens and he went on to play an anchor role on the second as he notched a first-class high score of 80.

The 22-year-old South African only got to play because Ben Duckett was away on England Lions duty, and grabbed his chance with both hands after coming in after opener Ben Slater had become the first of Harris' four dismissals.

He went on to feature in two 50+ partnerships, putting on 61 with Haseeb Hameed for the second wicket and then 78 with the quick-scoring Lyndon James for the fourth before he was bowled by Michael Neser.

Notts faced 35 minutes of pace bowling from Glamorgan's Australian duo of Neser and Hogan in the morning session before Lloyd and Harris took over. Harris maintained a good length and was rewarded with four wickets for his persistence.

He bowled Slater before Montgomery dug in with Hameed to steer Notts through to 130 for 1 at lunch. Ex-England opener Hameed looked in complete control as he hit 12 boundaries in his 70 before he, too, was bowled by Harris.

If Hameed had been guilty of a misjudgment in offering no shot to a ball from Harris that nipped back, so was Joe Clarke, who departed for 14. That brought James to the wicket and his attractive 50 included two sixes and six fours before he was caught at slip off Hogan.

Things went from bad to worse for Notts and once the Glamorgan pace attack got their hands on the new ball they quickly made inroads into the visitor's tail. Joey Evison was caught behind off Hogan's first ball and in the next over Neser removed Montgomery.

Hogan then mopped up, finishing with 4 for 47 from 20 overs compared to Harris' season-best return of 4 for 65 off 17, denying Notts a third batting point.
