|Royal London One-Day Cup, The Bristol County Ground|
|Gloucestershire 235 all out (47.5 overs): Dent 75, Roderick 74; Clarke 4-43|
|Surrey 88 all out (24 overs): Roy 19; Smith 3-7, Liddle 3-17|
|Gloucestershire beat Surrey by 147 runs|
Gloucestershire skittled Surrey for 88 to win their opening One-Day Cup game of 2019 by 147 runs at Bristol.
Chasing 236 for victory, Surrey lost Mark Stoneman in the first over and England opener Jason Roy went for 19.
Slow left-armer Tom Smith ran through the tail with 3-7 as Surrey were bowled in 24 overs with no batsman passing 20.
Earlier the hosts collapsed from 156-1 to 235 all out, starting when captain Chris Dent (75) and Gareth Roderick (74) were out in consecutive overs.
Surrey's woeful batting performance came despite naming a line-up packed with England internationals. As well as Roy and Stoneman. Rory Burns, Ben Foakes, Ollie Pope, Tom Curran and new signing Liam Plunkett all played.
They looked to have restricted Gloucestershire to a below-par total, with Curran (3-26) and Rikki Clarke (4-43) the chief architects in them losing their last nine wickets for 78 runs.
Once Stoneman was bowled by Australian paceman Dan Worrall third ball, and Chris Liddle took three quick wickets, Surrey folded to a huge loss with Roy top scorer on 19.
Surrey now travel to Hove to play Sussex on Friday, while Gloucestershire are next in action against Middlesex at Lord's on Sunday.
Gloucestershire head coach Richard Dawson:
"I didn't see the end coming quite that quickly, but it was the sort of pitch that new batsmen found hard to get going on.
"We had one brilliant partnership between Denty and Rodders and it proved enough. The message to the bowlers was to make sure that when they took a wicket they put pressure on the man coming in.
"We bowled really well perhaps some batsmen played big shots too early without assessing the conditions. It's only one game, but the great thing is we have won with plenty still to work on."
Surrey head coach Michael Di Venuto:
"It would be nice to start this competition well, but we have made a habit of doing the opposite in recent years. It was a particularly disappointing batting performance.
"We had a bit of bad luck with a few of the dismissals, strangles down the leg-side and a hit-wicket, but in general we didn't adapt to the sort of pitch we were playing on.
"Hopefully, we have got this out of our systems early and we will be looking to put things right quickly against Sussex at Hove on Friday."
