|Surrey 23pts Derbyshire 2pts|
Surrey moved up to third place in the Division Two table by completing an emphatic 10-wicket victory over Derbyshire on the final morning.
Set just 21 to win after bowling out the home side for 288 on the third day, they knocked off the runs in 5.5 overs.
Rory Burns picked up the single to take them to 21-0 and secure their second Championship win of the summer.
He finished five not out, with opening partner Zafar Ansari, who made a century in the first innings, on 15.
The pair were in no hurry at the start of play as Burns played out a maiden over from Mark Footitt, but Ansari collected a couple of boundaries off the same bowler before they reached the target.
Surrey will take great particular encouragement from the performances of Ansari, who also took five wickets in the game, and teenage seam bowler Tom Curran.
They were in control after 19-year-old Curran took 5-51 as the home side were bowled out for just 153 on the opening day.
For Derbyshire, who were relegated along with Surrey in 2013, their defeat checked any momentum gained by beating Leicestershire last week, and meant they remained next to bottom.
Surrey skipper Gary Wilson told BBC London 94.9:
"We actually got a bit lucky with the toss - it was a good toss to lose. They made the right decision in having a bat first, it was a dry wicket, but the way our bowlers performed on that first morning was outstanding and Tom, especially, was very good.
"Everyone is really pleased for Zafar. It's always special when someone gets that first first-class hundred and he certainly deserved it.
"He's turning into a real find at the top of the order. Hopefully, he can continue doing that job at the top of the order and I'm sure England will have half an eye on him."
BBC London 94.9's Mark Church:
"This was a proper team performance from Surrey and they will be quietly satisfied with their efforts over the three-and-a-half days in Derby.
"A second Championship win of the season is testament to the hard work that is being put in by the Surrey players and they are beginning to get the rewards they deserve.
"Twenty three points and a first away win in the Championship since 2011 will make the journey home down the motorway feel a little shorter."
