Hampshire 400 for 6 dec (Vince 159, Adams 65) drew with Surrey 99 for 2 (Burns 53*)
Hampshire's James Vince made the best of a heavily rain-affected draw with Surrey by hitting an impressive 159.
The result became inevitable after the third day at The Ageas Bowl was completely washed out after the first two days had been heavily interrupted by the weather and the captains could not come to an agreement over a manufacture result despite Graham Ford's positive talk the night before.
Hampshire resumed their first innings on 289 for 3 on day four and their opponents did not take long to make an impact as Will Smith added only three more to his overnight total of 23 before being caught off the bowling of Matt Dunn.
Vince, though, soldiered on and took his total past the 150-mark. Hampshire began to settle at the crease but Joe Gatting handed the momentum back to Surrey as he was caught by Dominic Sibley for 11 off the bowling of Stuart Meaker.
Just two overs later, another wicket fell and this time it Vince who was removed as Tom Curran (two drew a nick that went through to keeper Steven Davies. Vince's 159 was his third highest score for Hampshire and his second century of the season after he hit 144 against Gloucestershire a fortnight ago.
Sean Ervine (21) and Michael Bates (28) guided the hosts to 363 for 6 at lunch, and the unbeaten pair took their team to 400 before Hampshire declared.
The home side then enjoyed a strong start after the turnaround as Surrey captain Graeme Smith was dismissed lbw by James Tomlinson. Fellow opening batsman Rory Burns made use of the time available with a composed half-century that included seven fours and the 23-year-old was still unbeaten at the close of play.
The draw means Hampshire remain unbeaten and are now second in the table while Surrey are sixth and still looking for their first win of the season.
