Luke Procter hit his maiden first class century as Lancashire fought back strongly on day two of the LV=County Championship match with Gloucestershire at Bristol.
The Second Division champions-elect moved from an overnight 33-2 in their first innings to 292-7, with Procter hitting 106 and Tom Smith 88 not out, while Will Gidman bagged a four-wicket haul for the hosts.
A sixth-wicket partnership of 159 between Procter and Smith turned the course of the match, it enabled the visitors to move two bonus points nearer the title, having already clinched promotion, and ensured a memorable day for Lancastrian Procter in particular. His previous best first class score was 89 against Sussex at Hove in 2011.
The 25-year-old Oldham-born left-hander - who reached his ton off 208 balls - arrived at the wicket with the total on 38 when Gloucestershire wicketkeeper Gareth Roderick produced a superb diving catch to his right to send back Karl Brown for 23 off the bowling of Gidman.
Luis Reece helped add 67 as he sought an eighth successive half-century and a share of a county record. But the 23-year-old opener fell 15 short when bowled by left-armer David Payne attempting a big shot in the 32nd over.
Procter reached his fifty with a glorious straight drive off Howell and Smith followed to a half-century off 128 balls, with eight boundaries. The pair batted right through the afternoon and by tea had taken the score to 206-4.
After Gloucestershire took the second new ball they finally broke the partnership on 264 as Gidman, frustrated at having several big appeals rejected, finally pinned Procter lbw playing across the line.
Smith made good use of the reverse sweep against his namesake, Gloucestershire left-arm spinner Tom Smith, and also stood tall to dispatch the quicker bowlers with some attractive back-foot shots.
Left-arm seamer Taylor, 19, did get his maiden Championship wicket when Alex Davies was caught behind driving for 12. And Benny Howell followed up by having Glen Chapple caught at mid-on for a single.
