Mighty Win For England. They Lead 2 - 1 In Four Match Series!

Well, with six wickets to take, Toby R-J took two in consecutive balls in the morning session but could not get the hat trick. The same had happened earlier to Ben Stokes.
Tom Goddard was the last England spinner to get a hat trick - that was on Boxing Day, 1938 in Jo'burg.
He is no longer the last - Mo Ali is!

Two identical wickets. Elgar and Rabada, both left-handers, were caught at first slip from an off-break turning away from the bat out of the bowlers' rough. That ended his penultimate over. Mo had to wait for Stokesy to complete his over before lining up for the hat trick ball. It rammed into Morkel's pads and looked to be clearly hitting leg stump.
England - and Mo - were fortunate, at the end of the 80 overs to still have a review left when, inexplicably, the umpire failed to raise the finger. The review clearly showed what everyone else in the Oval already knew - and there it was! An England spinner with a hat trick - of a trio of left-handers! - Oh, and an England victory by a superb 239 runs!
