Trialist Garth Davson hit half-centuries on two successive days for Northamptonshire's Second XI against Surrey.
The first helped to save the Championship contest at Guildford - but the second wasn't enough to prevent the County losing their one-day Trophy contest at Charterhouse School.
The 23-year-old South African - who played in the Northants League for Stony Stratford in 2010 - hit 54, and together with James Kettleborough (58) and Lloyd Patternott (51 not out) steered Northamptonshire to safety on 272-6 in the three-day game.
The County batted right through the final day on Thursday to secure a well-deserved draw after conceding a big first-innings lead.
Then on Friday Davson led the way with 61 - backed up by Saif Zaib's unbeaten 47 - as Northamptonshire reached 245-6 in their allotted 50 overs.
But Surrey coasted home at 249-3 to win by seven wickets with plenty of overs to spare, thanks largely to 127 not out from Arun Harinath.
The seconds have three days at Desborough next week (August 12, 13, 14) for a Championship contest against MCC Universities.
