England named an unchanged 13-man squad Sunday for the fourth and final Test against Pakistan at The Oval next week after taking a 2-1 series lead at Edgbaston. In addition to the XI that won the third Test by 141 runs at Edgbaston Sunday, England also kept Nottinghamshire paceman Jake Ball and Yorkshire leg-spinner Adil Rashid in the squad. They could also bring in an as yet unnamed batsman after James Vince suffered an injury to the fourth or ring finger of his left hand while fielding in the slips Sunday. Hampshire captain Vince was taken to hospital for a scan to assess the extent of his injury. The fourth Test starts at The Oval in south London Thursday. England has ‘further to go' England captain Alastair Cook insisted his side had "further to go" after a win over Pakistan at Edgbaston gave it a chance to top the world Test rankings before the end of its home season. The host had it all to do after conceding a first-innings lead of 103 runs at Midlands county Warwickshire's headquarters. However, showing admirable resilience, England recovered to win the third Test by 141 runs Sunday to go 2-1 up with one to play ahead of the series finale at The Oval starting on Thursday. Victory in south London will see England back on top of the International Cricket Council's Test rankings for the first time since 2012 provided India does not win the last two Tests of its ongoing series in the West Indies. Not that Cook was getting carried away by the prospect. "If we do win at The Oval, I wouldn't say we are anywhere near our potential," he said. "If we become number one there, that's fantastic — but it will be a bit of an irrelevance, because this side has still got much further to go. "I thought that might come in a couple of years' time." England was behind in the game until Cook (66) and Alex Hales (54) wiped out the first-innings deficit with their first century stand as a Test-match opening pair. Joe Root (62) helped consolidate England's recovery before Jonny Bairstow (83) and Moeen Ali (86 not out) took the match away from Pakistan in Saturday's last session. Its sixth-wicket partnership of 152 eventually ended shortly before Cook declared early in Sunday's play with England 445 for six. "Everyone responded, and I think this side might have just toughened up a little bit," said Cook. Pakistan was left needing an unlikely 343 to win but a draw was a distinct possibility when it reached lunch on 69 for one. But its hopes of saving the game were all but ended shortly before tea by the loss of its last four recognized batsmen for just one run in 23 balls as England's pacemen made the most of the slight reverse swing on offer. "We were never leading it — but then, when we got our chance Saturday afternoon, Mo and ‘Bluey' (Bairstow) put the pressure on them," said Cook. "Then we bowled brilliantly too." What pleased Cook most, however, was seeing his side win from an unpromising position. "This is the first one in a while we've been behind and fought back." Meanwhile Pakistan captain Misbahul Haq, one of the quartet of batsmen who succumbed in the pre-tea collapse, said: "Until lunch it was easy, nothing happening. But after lunch they got it reversing, and we were not having any clue." However, he added: "The good thing is this match is gone. "We have one game left — we can win it and square the series — that's what we have to think."
