Opener Stephen Moore impressed with an unbeaten century as Derbyshire piled on the runs on the second day of their LV= County Championship Division Two match against Hampshire.
The former Lancashire batsman was 106 not out by stumps as the home side reached 203 for two, trailing by 125 runs after Hampshire were all out for 328 in their first innings.
Starting the day 231 for five after a weather-affected first day, the visitors lost Kyle Abbott for a duck after he was bowled out by Mark Footitt – his second wicket of the game in the first over of the day - but recovered thanks largely to a half century from Joe Gatting.
It was a timely innings from the former Brighton & Hove Albion footballer, who had scored just a single in his first two Championship knocks for his new county.
Sean Ervine (six) lost his wicket just five overs later – caught by Richard Johnson off Tim Groenewald – to fall cheaply and leave Hampshire on 248 for seven as Derbyshire continued to attack.
Gatting, who began the day on 25, passed the fifty mark and continued to cause problems before he was sent packing, caught by Chesney Hughes for Wes Durston's first wicket of the match.
Footitt bowled Matt Coles lbw for nine before Moore caught last man out Michael Bates.
In reply, Derbyshire lost opener Billy Godleman (one) early on to leave his side 4-1 in the third over as James Tomlinson trapped him leg before.
But Moore began to pile on the runs, reaching his ton off 178 balls in 227 minutes with a total of 14 fours and one six.
Wayne Madsen shared a 106-run second-wicket partnership with Moore before he was stumped for 36 runs by Bates for Liam Dawson's first wicket of the match.
That brought Hampshire nemesis Shivnarine Chanderpaul to the crease and, alongside Moore, the former West Indies captain reached 35 not out as Derbyshire saw out the second day in a strong position.
Chanderpaul is aiming to score his third Championship hundred against Hampshire for a third different county.
He reached three figures while playing for Lancashire in 2011 and again while wearing the Warwickshire badge 12 months later.
