Old Harbour will play in the SDC T20 final for the fourth time in its history after beating arch rival Greater Portmore by 30 runs at Ultimate Sports Club, St Ann today.The 2011 and 2012 champions will meet defending champions St Elizabeth’s Junction/Bull Savannah, who overpowered Heartease of St Thomas by seven wickets in the other semi-final played at the same venue. Old Harbour’s march to another final appearance was first laid by top order batsmen Ronville Brown, Devoy Royal and Erron Downer, as the south west St Catherine club posted a challenging 193 for three after being sent in to bat first. Brown ended the innings unbeaten on 72 after building an opening stand of 135 with the more attack-minded Gray, who made 68 from 40 balls. Brown’s 60-ball knock included nine boundaries, while Gray smashed five fours and five sixes in a brilliant display of power hitting. Downer, the hero of Old Harbour’s quarter-final win over Race Course, upped the ante in joining Brown, as he blazed a whirlwind 38 from 13 deliveries which included four maximums while hitting the boundary rope once. Fifty-four runs were added for the second wicket and Old Harbour were firmly in the driver’s seat, while Malcolm White (2-31) was the best bowler on the day for Greater Portmore.
