Erron Downer starred with both bat and ball for Old Harbour as the former champions edged a nail-biting one-wicket victory over Race Course to reach the SDC T20 semi-finals for the fourth time in history.Clarendon champions, Race Course played brilliantly, albeit in a losing effort, as they fell just short of the 157 victory target set by Old Harbour at the Three Hills Oval in St Mary on Sunday. If Race Course were brilliant then Old Harbour, particularly Downer was exceptionally brilliant bowling the last over with the Clarendonians needing 10 runs to secure an amazing triumph. All hopes rest on the shoulders of former West Indies bowler Krishmar Santokie, who smashed 21 runs off the 19th and penultimate over. The intense battle was, however, truly turn on its head when Santokie was off strike and Race Course needing two runs from the last three balls of the match. Downer kept his nerves like an experience pro, as Romario Edwards (28) and Santokie (55) were both caught respectively by schoolboys Krischon Givans and Robert Johnson off the fifth and sixth deliveries for a superb win. Earlier Race Course won the toss and inserted Old Harbour to bat first. Downer held the innings together with a topscore of 46, while Kamar Isaacs made 19, as the two-time champions posted 156 for nine off 20 overs. Hamlet Stewart was the pick of the Race Course bowlers with figures of three for 30. Race Course were pegged back early in their reply, reaching 60 for five after 11 overs. A 95-run partnership for the sixth wicket between Santokie and Edwards brought their team within the clutches of snatching victory, but were stopped dead in their tracks at 155 for seven by the heroics of Downer, who took two for 23.
