Glamorgan respond after Leicestershire's 500
Glamorgan 126 for 0 (Rudolph 63, Rees 53*) trail Leicestershire 500 (O'Brien 133, Cobb 63, Taylor 63, Naik 59, Wagg 4-107) by 374 runs
Glamorgan openers Gareth Rees and Jacques Rudolph made good progress with a half-century each as they looked to reel in a large Leicestershire total at Grace Road.
After a Niall O'Brien century, his 13th in first-class cricket, helped steer the hosts to 500 all out, Glamorgan responded in solid fashion with Rees and Rudolph unbeaten on 53 and 63 respectively as they reached 126 without loss at close of play.
Leicestershire had resumed on Monday at 221 for 4 with Josh Cobb on 49 and O'Brien on 46. Cobb reached 63 before he was caught and bowled by Dean Cosker as the hosts fell to 257 for 5, but O'Brien reached his ton in 117 balls and went on to make 133 where he was caught by Murray Goodwin off Graham Wagg.
Rob Taylor (63) and Jigar Naik (59no) also passed their half-centuries, adding 101 for the eighth wicket in 17 overs, and Leicestershire's strong batting performance continued right through their order with last man Charlie Shreck reaching a career-best 31 before his run-out brought an end to their resistance.
Wagg was the pick of the bowlers for the visitors, taking 4 for 107 from his 27 overs.
