Hampshire had the better of Yorkshire on day two of their LV= County Championship Division One clash at Headingley.
Rain kept the sides off until 2.30pm but there was still plenty of time for Hampshire to reach 427 all out and reduce Yorkshire to 100-3.
Yorkshire initially struggled to 32-3 but were then lifted by left-handers, Phil Jaques and Gary Ballance, who both notched centuries in the victory over Gloucestershire last week.
Jaques had moved to 59 by the close, with Ballance on 26, leaving Yorkshire on 100-3 and still requiring a further 178 to avoid the possibility of the follow on.
Early rain ate up 37 overs of play, with Hampshire eventually resuming on 352-5 off 96 overs, with Simon Katich on 180 and Michael Bates 88.
Bates showed few nerves as he made his way towards a maiden first-class century, producing a classic cover drive off Steve Patterson to canter to 96 and in the same over placing him backward of point to reach three figures off 151 balls with 19 boundaries.
The wicketkeeper-batsman did not last much longer, however, ran out by Andrew Gale after some clunky running from Katich.
The sixth-wicket stand of 170 equalled Hampshire’s previous best – a mark set by Phil Mead and Gerald Harrison at Southampton in 1914.
Katich looked an odds-on certainty for a double century but, in trying to get there with a big hit over the top, he was deceived by Adil Rashid’s flight and skied the ball to Joe Root at wide mid-on. The Australian left-hander’s 196 contained 22 boundaries and came off 265 deliveries.
Chris Wood drove Patterson to Root at cover and at 395-8 in the 108th over both sides were still hopeful of picking up a further bonus point.
Kabir Ali achieved it for Hampshire by thumping a long hop from Rashid through the covers for four to take his side beyond 400.
The tail wagged for a while but Rashid went on to pick up the wickets of both Ali and James Tomlinson to finish with 3-86.
Yet overall it was another disappointing performance from the leg-spinner, whose place is coming under increasing threat from off-spinner Azeem Rafiq.
Patterson also claimed three wickets and was the pick of a weak attack which should be strengthened when Australian paceman Mitchell Starc makes his debut against Derbyshire in the CB40 League match at Headingley on Sunday.
Yorkshire got off to a bad start as Adam Lyth fell lbw shouldering arms to Ali in the first over and Root occupied the crease for 44 balls in making eight before edging David Balcombe low to Liam Dawson at second slip.
A brilliant piece of fielding by Michael Carberry then sent back skipper Gale after he had faced only one ball.
Jaques played Wood through the off-side and set off for a single, Carberry swooping on the ball to transfer it to his right hand and throw down the stumps with a direct hit.
Jaques found a reliable partner in Ballance and the pair weathered the sharp four-man pace attack to improve Yorkshire’s position.
They put on 50 together in 13 overs and Jaques completed his half-century off 108 balls with seven boundaries.
