Rain thwarted Glamorgan's efforts to bat Surrey out of the match on day three of their LV= County Championship match at The Oval.

The visitors were 46 without loss in their second innings - 181 ahead overall - when play was called off for the day at 4.15pm.

Less than 14 overs were bowled before the weather put paid to any further play before lunch, in which time Glamorgan made short work of mopping up the Surrey tail as Chris Ashling claimed career-best figures of four for 47.

Gareth Batty fended the second ball of the day low to the left of Gareth Rees at short leg to hand Will Owen a third scalp and then Ashling plucked out Chris Jordan's off stump to make it 267 for eight.

Three overs later, Chris Schofield spared Surrey the ignominy of following on when he took a single to long-on against Dean Cosker.

But, having progressed to 30, Schofield skied an ugly slog-sweep to Cosker running in from cover. Tim Linley departed moments later as Cosker drew a line under Surrey's 284.

Heavy showers limited the afternoon session to little more than 11 overs' action. Setting out with a 135-run first-innings lead, Rees and Will Bragg added an unbeaten 46 for Glamorgan's first wicket before the heavens opened at 3.15pm.

Bragg cut and then straight drove Jade Dernbach for successive boundaries as Tom Maynard carried out a creditable job behind the stumps in the absence of Steven Davies, who withdrew with an ankle problem, until Rory Burns, Surrey's 2nd XI wicketkeeper arrived at The Oval.
