Harare - The Proteas will be going in with their strongest possible XI for their final Triangular series one-day international (ODI) against Zimbabwe at the Harare Sports Club on Thursday. Coach Russell Domingo has stressed the importance of pulling off a strong win against Zimbabwe to book their place in the final. "It's an important game," Domingo stressed. "A couple of guys have been rested this series; Dale and Morné have played two matches in the last three or four weeks, I don’t think its important for them to rest, they will be having a few weeks off after this tour. "AB (de Villiers) also had a few days of rest so I think we will be going in with our strongest possible team."You want to win every game that you play for South Africa, regardless of who the opposition is. "It's important for us to win strongly, if we do, it will give us a good boost leading into the final on Saturday."Domingo says the Proteas will need to improve on the execution of various disciplines, after an “average” performance against Australia on Tuesday."We didn’t play as well as we would have like to," Domingo admitted. "Obviously with the ball in the back end I don’t feel that we executed our plans well enough there. "Our team at the moment, with a little bit of a long tail, is set up to have wickets in hand, we were five or six down, those are the areas that we really got wrong yesterday."Faf du Plessis and Aaron Phangiso continue to impress in their respective roles, a pleasing aspect for Domingo."There were some positives," Domingo said. "I thought Phangi (Phangiso) bowled outstandingly yesterday and Faf (Du Plessis) has continued his good form at number three. "Those are great performances for guys who are establishing themselves in the side."
