A century from Steven Mullaney in only his second first-class match as an opener was backed up by Samit Patel's 87 not out as Nottinghamshire moved themselves into a winning position against Surrey in LV= County Championship Division One.
Mullaney hit 12 fours and a six in a superb innings of 104 off 201 balls to help Nottinghamshire to 360 for six by stumps on day two in response the hosts’ below-par first innings 198 at the Kia Oval
His efforts, along with those of Patel, ensured Chris Read's team will now be sniffing an innings-victory on a pitch expected to take more spin as the game goes on.
Mullaney added 105 for the first wicket with Riki Wessels, who made 47, and then a further 50 with Michael Lumb for the second.
Surrey briefly threatened to mount a fightback with the ball when slow left-armer Gary Keedy tempted James Taylor down the pitch to have him stumped by Steven Davies for five, soon after Chris Tremlett had won an lbw appeal against Lumb on 22.
That left Notts on 168 for three but Patel, initially in partnership with Mullaney and later in further useful stands with David Hussey, Read and Ajmal Shahzad, batted with great confidence and composure to make sure there was no way back into the game for Surrey in the second half of a long, hot day in the field for the home side.
Patel struck 12 fours from 149 balls to hold the innings together once Mullaney, with the total on 207, had tried to send a ball from Zafar Ansari to the deep midwicket boundary but succeeded only in mis-hitting a simple looping catch to Rory Burns at wide mid-on.
Hussey, pulling Ansari and then straight-driving Keedy for sixes either side of tea, increased the tempo in a stand of 58 with Patel until he thumped a return catch on 37 to the latter, who did well to hold on to a stinging drive at waist height.
Read enjoyed escapes on 13 and 15 when he edged Tremlett just short of first slip then Jade Dernbach for four between wicketkeeper Davies and first slip, both of whom could only get a fingertip on the ball.
However, on 31 the Notts skipper was beaten and bowled when Tremlett extracted some rare seam movement out of a still sluggish surface.
Tremlett did not appear in Surrey's attack until the morning session's 17th over but made an instant impact, trapping Wessels leg-before with his first ball.
Surrey bowled Keedy and off-spinner Gareth Batty in tandem for much of the day, after Notts had resumed on 50 without loss, but the spin pair won only slow turn from the pitch.
Tremlett, who got through 17 overs in the day, was the main threat, with figures so far of 3-71 from 23 overs, but his team-mates face two further days of toil to prevent Notts from heading home with a victory.
