England call up teenage spinner Rehan Ahmed for second Ashes Test at Lord's

Ahmed became the youngest man to play Test cricket for England when he was picked to take on Pakistan in December, earning his cap 126 days after his 18th birthday.

He made an eye-catching debut in Karachi, taking seven wickets in the match and five for 48 in the second innings, and will join Ben Stokes™ side this weekend as cover for Moeen.

The decision represents a typically bold gambit from the current England regime, with Ahmed's raw ability over-riding a quiet start to the season with Leicestershire.

He has taken a modest six wickets in seven in Division Two of the County Championship, with an average of 67.66 and an economy rate of 4.01.

There is every chance he will not be in the side against Australia on Wednesday, with Moeen still hopeful of being passed fit and the possibility of England playing a four-man seam attack augmented by Joe Root's off-breaks. But his promotion to the squad represents a further reminder of England's fearlessness.

Moeen, who is twice Ahmed's age at 36, struggled throughout the two-wicket defeat at Edgbaston due to a burst blister on his right index figure.

The wound will continue to be monitored over the coming days as England's medical staff attempt to get him ready to go again but, after two years away from first-class cricket, a recurrence cannot be ruled out.

That left the selectors seeking a potential stand-in, with Ahmed edging out the likes of Surrey's Will Jacks, and Hampshire's Liam Dawson to get the nod.

Jacks, who also made his debut in the Pakistan series, showed off his 'Bazball' credentials with the bat in Thursday's T20 Blast clash against Middlesex as he hammered five sixes in an over to make 96 in 45 balls, but his off-spin remains a work in progress.

He went for 30 off three overs in the same game and has just two first-class wickets this season.

Slow left-armer Dawson is arguably the most reliable available option but played the last of his three Tests in 2017.

In the end, the allure of Ahmed's wrist-spin won the day and he will link up with the squad in London over the weekend.
