Vince & Northeast (58) put on 142
Hampshire make 348-9
Yorkshire slump to 241 all out
Tattersall makes valiant 89 for Tykes

Pujara c Adams b Steyn 0 (Yorkshire 15-2)
Another one goes - it's a beauty from Dale Steyn.
The big paceman gets one to leap up at Cheteshwar Pujara and the India batsman can only fend it to slip where Jimmy Adams takes a diving catch.
It was a cracking delivery, Pujara could do little about it.
Yorkshire 14-1 - target 349

I think Yorkshire will learn a lot from the way James Vince played in the first innings. He hit the bad ball, he didn't look to be too aggressive, just played his natural game.
The feeling is when you have such a massive score, you've got to get the runs in the first 10 overs.
Kohler-Cadmore 2, Pujara 0
Yep, Adam Lyth's lbw dismissal was high. The ball would have gone over the top.
No DRS in the One-Day Cup, so if you're given, you go.
Meanwhile Cheteshwar Pujara is the new man in having returned early from India's two-day Test win over Afghanistan.
Lyth lbw b Wood 11 (Yorkshire 14-1)
Adam Lyth is out. Big blow for Yorkshire.
Chris Wood nips one back in to the opener, it smacks him on the pad and up goes the umpire's finger.
It looked a little high on first viewing, but Lyth is on his way.
Lyth 9, Kohler-Cadmore 1
I'm not sure it was the most sensible move by Adam Lyth to punch Dale Steyn's second ball for four.
The South Africa paceman is fired up - digging in a couple of rapid bouncers to the former England opener.
Ah, but the 34-year-old then overpitches and Lyth punishes him once again through the off side.
Steyn is steaming.
Lyth 5, Kohler-Cadmore 1
Left-arm seamer Chris Wood shares the new ball with Dale Steyn and it's a good first over.
Just the two singles as he finds a nice line and length straight away.
Lyth 4, Kohler-Cadmore 0
Yep, Dale Steyn did not enjoy being stroked through the covers.
He returns with an absolute jaffa that nips past Adam Lyth's outside edge.
Decent bowler is Dale.

John Abernethy: Couldn't agree more about Yorkshire being without five players. Can you just imagine the fuss if a Premier league team had to play under the same rules. I think cricket sometimes doesn't do the game justice.
Sam Ager: It's sad that this semi final is being played on a Monday starting at 11. Missed the chance for a big crowd in. ECB need to look at themselves.
Lyth 4, Kohler-Cadmore 0
Hello Mr Steyn.
Adam Lyth creams his second ball through the covers to the rope. Gorgeous.
Interval: Hampshire 348-9 v Yorkshire
South Africa fast bowler Dale Steyn will be taking the new ball for Hampshire. It doesn't get much tougher than that.
Adam Lyth to face.
Interval: Hampshire 348-9 v Yorkshire
Cheers Josh.
It was some innings from James Vince, one of the best I've ever seen.
Some of his timing was from another planet.
Anyway, Yorkshire have some classy players in their batting line-up.
Let's see how they do...
Interval: Hampshire 348-9 v Yorkshire
Okay then, the players are just about ready to resume.
Yorkshire openers Adam Lyth and Tom Kohler-Cadmore have a big job on their hands to get the Tykes off to a flier in their pursuit of 349.
Gary Smee is back for the first half of the innings.
The County Championship continues at full steam on Wednesday, with nine fixtures getting under way.

James Vince had a chance of becoming the first Hampshire batsman to score 200 in List A cricket before he was caught superbly on the boundary by Tom Kohler-Cadmore.
The 27-year-old hit 20 fours and three sixes in his 126-ball knock and was just seven runs short of his own highest List A score for Hampshire...

Liam Dawson was the next to go...
