All-rounder Leacock provided much needed inspiration for the St Catherine side who had earlier watched on as their captain Derek Bishop was helped off the field and taken away for medical attention after setting the home team a modest 170 off a minimum of 41 overs for victory.
Full length
Obeying the tenets of bowling a consistent full length on the stumps he removed the first five Empire batsmen to thwart the hosts' run chase after an opening partnership of 60 in 11 overs between Haynes and Jason Parris seemed to set "The Blues" on the way to full points.
First he induced a lofted drive from Parris to have the burly Parris caught in the covers before bowling Jason Hinds and winning lbw appeals against Antonio Greenidge and Theo Chandler.
Leacock (34) also featured with the bat in the visitors' second innings helping the lower order to rally to 174 from a precarious 99 for six in the face of an incisive spell from left-arm pacer Ian Perryman (5-42).
Haynes (74 not out) found a stubborn partner in teenager Rico Williams who stayed with his skipper for 52 minutes before fading light brought the match to a premature end due to fading light with ten overs remaining.
