Stephen Peters struck his second century of the season as Northamptonshire's batsmen dominated the first day of their LV= County Championship match against Glamorgan at Wantage Road.

Peters was the star of the Division Two top-of-table clash making 115 off 171 balls, including 16 fours, as Northants closed the day in a strong position on 325 for three.

Rob White then made a century of his own as he ended the day unbeaten on 101 from 241 deliveries.

Glamorgan, who started the day three points behind their opponents in the table, struggled with the ball throughout, although Chris Ashling did take two for 74.

Northamptonshire won the toss and chose to bat and Ben Howgego was given a second life when he was dropped at gully by Dean Cosker off the bowling of Alex Jones in the sixth over.

He made it to 26 before his off stump was hit by former England spinner Robert Croft to break an opening stand of 72 with Peters.

Peters, whose previous century came against Essex, went on to complete a fluent half-century off 69 balls as Northants had the best of the opening session, reaching lunch on 117 for one.

White was then given a scare when he edged Croft's delivery on 22 but Glamorgan wicket-keeper Mark Wallace could not take the catch.

Peters remained untroubled in completing his century off 149 balls with a four through mid-wicket off Cosker to notch his 26th first-class ton.

This came as part of a partnership of 133 with White, which was broken when Peters holed out by hooking Ashling high into the air to Gareth Rees at deep fine leg, who took a fine catch after waiting for the ball to drop.

The home side finished the afternoon on 214 for two before White completed a slow half-century off 154 deliveries in the third over after tea.

He and Alex Wakely stuck around until Glamorgan captain Alviro Petersen took the second new ball midway through the 86th over as he resorted to restricting Northants' run-rate by bowling spin from both ends.

Four byes off Ashling brought up the 100 partnership before Wakely fell on 45 when he dragged the same bowler's delivery on to his middle stump.

White then completed his sixth County Championship century and his first since September 2009 off 232 balls.

He and keeper David Murphy saw out the rest of the day and the latter will resume on 12 on Monday.
