Essex vice-captain and top-order batsman Tom Westley is set to earn his first cap for England with selectors confirming he will bat at number three in the 100th Test at the Oval.

Westley has been in good form for Essex where he has scored 478 runs in the Championship this season, including two centuries, at an average of 53.11.

He also impressed for the England Lions last winter and at Worcester last month, where he scored 106 not out against South Africa’s full strength bowling attack.

The 28-year-old has long been viewed as in the England reckoning and he will now get his first chance to impress in full England colours alongside Essex teammate Alastair Cook.

Middlesex batsman Dawid Malan is also included in the squad for the first time and could feature if England decide on selecting an extra batsmen when they confirm their starting line-up next week.

Malan, who made his England debut last month in the deciding T20 against South Africa, where he scored 78 off 44 balls in Cardiff, has been a consistent performer with Middlesex in red-ball cricket.

He averages 42.50 in the Specsavers County Championship this season with a highest score of 115.

England will report to the Kia Oval on Tuesday, where they will train in the afternoon.

England National Cricket Selectors have named the following 13-man squad for the third Investec Test match against South Africa starting at the Kia Oval on Thursday July 27 2017.
