Ryan Rickelton is showing the value of runs under the belt. He came into the Champions Trophy on the back of a solid SA20, where he was the fourth-highest scorer. Before that, he had smoked 259 in the New Year’s Test against Pakistan. On Friday, it was time for him to leave his mark on the 50-over format as he scored his maiden ODI century in his seventh game as South Africa began their Champions Trophy with a solid 107-run win over Afghanistan.

Batting first on a Karachi surface that had a nice layer of grass, South Africa rode on Rickelton’s 103 followed by steady fifties from Temba Bavuma,  Rassie van der Dussen and Aiden Markram  to rack up 315 for 6. That meant Afghanistan had to record their highest-ever successful chase if they had to win on Champions Trophy debut.

But they never really got close. Rahmat Shah  was the only bright spot as he scored a sprightly 90 off 92 balls, and was the last batter to fall. But with a second-highest score of 18, Afghanistan were never really in it. Kagiso Rabada  picked up three wickets, while Lungi Ngidi and Wiaan Mulder  got two each as Afghanistan were bundled for 208 in 43.3 overs.

It was a largely flawless innings from Rickelton. He never looked rushed; not when Tony de Zorzi fell early or when Bavuma took his time to get going. Rickelton struck boundaries whenever he got a chance. When he didn’t, he quietly rotated the strike. He started with a lovely punch past mid-off third ball before going back-to-back against Fazalhaq Farooqi in the fifth over, once with a fierce pull through midwicket and then a cut past point.

De Zorzi also struck two fours but fell to a rather nonchalant delivery from Mohammad Nabi early on when he flopped it straight to mid-on

Bavuma’s first 19 balls yielded only seven runs before he got a couple of fours away to get into the groove. Rickelton, meanwhile, picked Azmatullah Omarzai for two delightful fours to raise his fifty off just 48 balls.

South Africa ticked along to 83 for 1 after 15 overs, but an important passage of play was about to come: South Africa batters vs Afghanistan’s spinners. That’s where Rickelton really showed his wares. He would have faced a lot of Rashid Khan in the SA20 nets as they were part of the victorious MI Cape Town side, and that experience showed.

Bavuma got to his second fifty away from home, as he continued his rich form. He had a solid 129-run stand for the second wicket with Rickelton, before holing out to deep midwicket as Nabi picked his second wicket.

By that time, Rickelton had moved into his 90s, and had hardly broken a sweat. Afghanistan hardly helped themselves in the field, too. There were several misfields, and a run-out chance fluffed, while Noor Ahmad was particularly off-colour. He was either too short, or too full, and often tried to dart the ball in and lost his shape.

Rickelton soon became the first South Africa batter to register a century on Champions Trophy debut with a push to long-off.

Afghanistan got a lucky break when Rickelton was run-out in bizarre fashion. He bunted a Rashid length ball back to the bowler, who fired a flat throw to the wicketkeeper. Rickelton, out of his crease, was caught off-guard just a touch, and as he put in the dive, his bat bounced just short of the crease. That meant even though his bat was over the line, it was in the air when Rahmanullah Gurbaz whipped the bails off.

There was no respite for Afghanistan though. Van der Dussen, coming into the tournament not in great nick, was fluent and Markram found his stride as well, with both batters recording fifties. The last five overs yielded South Africa 51 runs as they posted an above-par total.

For Afghanistan to chase down 316, it was imperative for Gurbaz to get going. But South Africa’s new-ball bowlers weren’t ready to give him an inch. Ngidi’s short-of-a-length ball got the better of Gurbaz as he got a top-edge to short fine leg. No. 3 Sediqullah Atal struggled big time. Ibrahim Zadran finally broke the shackles by hammering Rabada over wide long-on. That obviously did not please the bowler, who returned with a 148.3kph thunderbolt and sent Ibrahim’s middle stump splat.

The South Africa pace bowlers concentrated on that hard length. According to ESPNcricinfo’s ball-by-ball data, in the first 15 overs, 33 of the balls bowled by South Africa were either short or short-of-a-good length.
