Blaise Bicknell recovered from a second set slump to beat Kaipo Marshall and give Jamaica the advantage against Barbados following the first rubber of their World Group II Davis Cup playoff tie at the Eric Bell Tennis Centre in Kingston on Saturday.
Bicknell prevailed 6-1 3-6 6-1.
Despite a sluggish start, and the first three games going to deuce, Bicknell saved break point in the opening game of the contest and fought to a 3-0 lead, before ultimately running away with the set 6-1.
The 21-year-old Barbadian responded in the second set, breaking early, before shocking the partisan crowd by rushing to a 3-0 lead.
However, the 22-year-old Bicknell, ranked 319 in the world and number one in the Caribbean, momentarily pulled his game together with precise serving and strong forehands to level at three apiece.
The momentum again shifted with Marshall breaking once on his way to winning the next three games and take the set 6-3.
He saved three break points and squandered three set points, before holding his nerve when Bicknell dumped a backhand return in the net.
Last year, Marshall heroically, came from a set and 4-5 down to beat Pacific Oceania's Clement Mainguy to keep Barbados in group II, but he couldn't complete this mission, as Bicknell, sensing the challenge, stepped up and ran away with the third 6-1, punctuating the victory with a second serve ace.
"I didn't play my best but I found a way to get the job done," Bicknell said following the win in sweltering heat.
"I played a good first and third set and once I relaxed I was comfortable,” he added.
Marshall also felt he was far from his best.
"I definitely didn't play the level I wanted to today, I felt definitely like I was right there with him, but I felt like I defeated myself,” he lamented.
Neither player hit their best game on the day, but ultimately, Bicknell's superior quality was the difference.
There were moments he looked like the man who is coming off his first ATP challenger title. His serve out wide on the deuce court in big moments was a major factor, and his heavy forehand also did a lot of damage.
Marshall struggled on second serve. He hit four doubles in his first service game, a problem which persisted throughout the match.
The day's second rubber between Darian King of Barbados and Rowland Phillips of Jamaica is currently underway.
Action concludes on Sunday with the doubles rubber and reverse singles.
