The latest completed round of the domestic Four-Day Series took the form of a damp squib, with only one completed fixture out of four. However, that completed game between the Knights and the Dolphins was handsomely won by the latter in Mangaung and included stand-out displays from Sarel Erwee, who was dropped from the Proteas Test squad to face the West Indies, South Africa's number one spinner Keshav Maharaj, and newly drafted pacer Gerald Coetzee. There was an assortment of conversions, starts, and non-starts from a variety of selected and jettisoned players that made things interesting from a playing perspective this week. They are as follows: Sarel Erwee (132 off 141) and Keshav Maharaj (5/62 and 6/43) Keshav Maharaj has dusted off the Australian tour cobwebs. Having collected nine wickets in last week's eight-wicket win against Western Province, Mahara followed that up with an 11-wicket haul in the Dolphins' 279-run win against the Knights. He was always going to be a first pick from a spinning perspective, but for Sarel Erwee, his quick-fire 100 was a necessary return to form for the discarded opener. After last week's melancholic tweet on the eve of his dropping, he tweeted this on Wednesday: It may have been a reference to Sunrisers Eastern Cape teammate Roelof van der Merwe following him on Twitter, but it also spoke of a man in a far better happy space. More of those tons will be needed though. Gerald Coetzee (5/56) How do you celebrate a Proteas Test call-up? Well, a five-wicket haul as a bowler is the best way to do so. Coetzee, across all formats, has been performing well, especially in a struggling side like the Knights, who have a relegation struggle on their hands. Three of Coetzee's five wickets in the first innings against the Dolphins were top-five batters, while he also collected those of Eathan Bosch and Maharaj. His wicket pickings were slimmer in the second innings, but the message has been sent. Ryan Rickelton (125 off 111) If it wasn't for rain and bad light combining that lopped precious time out of the game between the Lions and the Warriors on day two, a result could have been reached. There were three 100s in this game, but from a Proteas' perspective, Ryan Rickelton's one was the most significant. He has been called up for the West Indies series and with these runs, he'll ever so slightly ask a starting question about the number five batting slot for the Proteas for next week's first Test at SuperSport Park. That slot has been filled by Khaya Zondo, who made 55 in the Dolphins' second innings. It may have rained on Monday to spoil what could have been a tantalisingly poised game, but it certainly didn't rain on Rickelton's batting parade. Kyle Verreynne (64 off 113) Rain, on this occasion, got in the way of Kyle Verreynne's attempt at fighting for his spot, but when the conditions dried enough for play to take place in Potchefstroom between Western Province and the North-West Dragons, Verryenne cashed in. His 64 was the second-highest score in WP's dig and made up for the slight disappointment of making only eight and three in last week's loss against Dolphins. However, a mightier batting effort will be needed to supplant the two keepers ahead of him in Rickelton and Heinrich Klaasen. Tony de Zorzi (18 off 32) Scores of nine, 13, and 18 aren't exactly the kind of numbers Tony de Zorzi would want to take with him to the Proteas when he joins the camp this weekend. The Kingsmead excursion could be excused because, across the first three innings against the Dolphins, batting was a difficult exercise before Bryce Parsons made it look easy with his fourth-innings ton. That said, batters are allowed a small blip, and De Zorzi can afford one, but with the race for runs at fever pitch, it can't be allowed to last long. Surprise picks - Matthew Breetzke (102 off 180) and Sinethemba Qeshile (124 off 215) The importance of the tons from these two Warriors tyros cannot be underestimated. The Warriors have been a team of bit parts coming together at crucial times, so the first and third innings knocks from Qeshile and Breetzke respectively came at a good time for both batters. Should they finish the season on a high, they'll make selection for any South Africa A side rather interesting. .
