|LV= County Championship Division Two, The Kia Oval|
|Close, day three: Surrey 474-8 dec v Hampshire 167-3|
|Surrey 5pts, Hampshire 2pts|
Skipper Jimmy Adams again missed out on a century after laying a solid foundation for Hampshire in reply to Surrey's 474-8 declared at The Oval.
Adams passed 50 for the sixth time this season, but was lbw to Gareth Batty for 79 after he and Will Smith added 129.
Smith was 61 not out as the Division Two leaders reached 167-3 at the close.
Earlier, Jason Roy failed to add to his overnight 114 for Surrey, but captain Gary Wilson made 82 as they picked up maximum batting points.
The home side batted positively to add 89 for the loss of Roy, who was lbw to Kyle Abbott, Wilson and Kevin O'Brien, with Batty (27) and Tim Linley (21) sharing an unbroken stand of 44 before the declaration came.
Hampshire soon lost Michael Carberry, who was caught behind off Matt Dunn for six, but Adams and Smith were together for 50 overs to put their side in a good position to avoid the follow-on, although the latter was dropped by Rory Burns at short-leg on 16 and again by Roy at slip when he was on 22.
As well as Adams' wicket, Batty (2-35) also won an lbw decision against James Vince, who only made seven before playing back to a ball that turned out of the rough.
Rain then forced the players off a few minutes early - but barring a final-day collapse by Hampshire, a draw is the most likely result.
Surrey batsman Jason Roy:
"I don't think I have batted better in four-day cricket.
"I had a nice partnership with Gary Wilson and just kept things simple. It was disappointing to get out so early today but they bowled well at us.
"Our spinners then bowled really well and if we are patient tomorrow, then we might be able to pull off a miraculous win."
Hampshire captain Jimmy Adams:
"Their bowlers did stifle us a bit after tea, but it's still a pretty good wicket to bat on.
"There is some turn and occasionally the ball is keeping low but there aren't too many gremlins in the pitch.
"I think we're good enough to get through tomorrow if we bat sensibly."
