Tabraiz Shamsi was "relieved" as his heroics helped South Africa edge to a one-run victory over Nepal at the T20 World Cup in Kingstown.

Nepal looked on the verge of a shock victory, needing two from the final ball to secure the win. However, Ghulsan Jha was run out at the non-striker's end as South Africa came through unscathed to make it four wins from four at the tournament.

Despite Ottniel Baartman bowling the final over, it was Shamsi's 4-19 that proved crucial in South Africa getting over the line, including two wickets in the 18th over to turn the game back in his team's favour.

The spinner was thankful South Africa avoided an unlikely defeat, telling reporters: "[I am] definitely relieved.

"The team is standing up to the pressure and that's great to see."

Proteas captain Aiden Markram praised the efforts of Nepal, whose narrow defeat means they are eliminated from the competition with one game to spare in Group D.

"You have to give Nepal a lot of credit," Markram said. "Throughout the game they put us under a lot of pressure, and it shows the quality they have."

While Nepal skipper Rohit Paudel was disappointed in the defeat, he also took pride in how his team fared against one of the tournament favourites.

"I'm very proud of the unit, the way we bowled and batted," Paudel stated. "We were very close but a little far."

West Indies A’s tour of Nepal got off to an unfortunate start, after they suffered a four-wicket loss to their host in a high scoring opening fixture of their five-match Twenty20 series at the Tribhuvan University International Cricket Ground in Kirtipur, on Saturday.

Set a formidable 204 by West Indies A, Nepal’s thrilling victory, which was set up by a captain’s knock from Rohit Paudel, etched their names in the history books, as they successfully got to their target at 206-6 with two balls to spare.

Paudel smashed a 54-ball 112, including 10 fours and two sixes to see his team to a 1-0 lead in the series, which West Indies Head coach Darren Sammy said offers his team a chance to define roles and personnel more clearly for their ICC Men’s T20 World Cup squad.

However, the Caribbean side’s all-round effort was found wanting, as only captain Roston Chase (74), Alick Athanaze (47) and Keacy Carty (38) offered any resistance with the bat, while only Obed McCoy (2-34) and Matthew Forde (2-49) had some semblance of success with the ball.

Scores: West Indies A 204-5 (20 overs); Nepal 206-6 (19.4 overs)

Asked to take first strike, after losing the toss, West Indies A suffered an early blow, as they lost Johnson Charles (zero) off the last ball of the opening over, with 16 runs on the board. Andre Fletcher (13) stuck two sixes off five balls, before he too departed via the run-out route, leaving West Indies A at 43-2 in the fourth over.

However, Athanaze went about business, striking three sixes and five fours in a 25-ball knock, as he put on 43 for the third wicket with Chase, prior to his demise. From there, Chase and Carty added another 60 runs in a fourth-wicket stand that defined the innings.

Carty’s 38 off 26 balls, included two fours and three sixes, while Chase, who anchored the innings with a captain’s knock, struck nine fours and two sixes in his 46-ball 74. Kadeem Alleyne, on 14, and Keemo Paul, one, were left not out.

No Nepal bowler took more than one wicket.

With runs on the board, West Indies A would have felt confident of wrapping up a win, even more so, after Forde and McCoy combined to remove openers Anil Sah (five) and Kushal Bhurtel (16) to have Nepal at 38-2 in the fifth over.

West Indies remained in the ascendancy when Fletcher and Charles combined to run out Kushal Malla (16), leaving their host on the ropes at 82-3 at the halfway mark.

However, Paudel showed class, in not only reviving his team’s innings, but pushed them all the way with some aggressive stroke play, assisted by wayward bowling from West Indies A attack at times. Dipendra Singh Airee (24) offered support to his captain in getting Nepal across the line for a famous victory.
