[4] His next fight came against Ronnie Clark for the vacant IBF European super-featherweight title on 24 February 2018 at the York Hall, London.
The next few rounds saw much of the same; Barrett throwing punches from range and Clark forcing the pace to work at close quarters.
After being warned for a low blow, Barrett was dropped to the canvas 1 minute into the sixth-round by a straight left-right uppercut combination from southpaw Clark.
In a fight that saw McCorry lose a point for hitting after the bell at the end of the eighth, he was dropped three times; firstly in the third-round resulting from a left hook to the body; again in the eighth from a right hand to the body; and finally in the ninth-round from an uppercut, causing referee Steve Gray to wave the fight off at 1:43[9] into the round to see Barrett retain his title with a ninth-round TKO.
[10] Barrett was booked to face the unbeaten Eric Donovan for the vacant IBF Inter-Continental junior-lightweight title on 14 August 2020, at the Matchroom Fight Camp in Brentwood, England.
[23] On Christmas day in 2011, Barrett's older cousin, John, was attacked at a private party held at Sinclair's Bar in Rochdale, Greater Manchester.
