Left-arm orthodox spinner Keshav Maharaj is set for his first ODI tour after being named in South Africa's 15-man squad for the ICC Champions Trophy.
The Proteas will take on England in three ODIs from May 24 in Leeds before launching into their Champions Trophy campaign on June 3 against Sri Lanka in London.
Maharaj made his Test debut against Australia last November in Perth and has gone on to claim 26 wickets at 25.88 from seven matches, including an innings best of 6-40 against New Zealand in Wellington last month.

"We have seen how important it is to bat deep in ODI cricket, this option will give us that cover if needed."

"I look at the side now and am struggling to find a weak link as there are lots of quality options with the ball as well as with the bat.
"The three games against England in May will help the players acclimatise to English pitches and conditions ahead of the first ball of the tournament, and it’s important that they play those games as close to tournament intensity as possible.
