A century from Ben Foakes and half-centuries by Jamie Smith, Cameron Steel and former Bear Dom Sibley put Division One leaders Surrey in a strong position on Day One of their crunch match against Warwickshire at the Kia Oval.
Surrey finished on 339 for 4 with England wicketkeeper Foakes (112*) stifling the Bears who had taken two early wickets to leave the title favourites on 31 for 2.
