Cape Town - Justin Kemp and Robbie Peterson made a double strike in the last four overs of the second day to give the Cape Cobras the advantage over the Dolphins in their SuperSport Series match at Newlands on Friday.The Dolphins were making a spirited reply to the Cobras’ first innings total of 337 thanks to a 98-run partnership for the third wicket between Imraan Khan and Devon Conway. Conway (51 off 92 balls, 9 fours) was caught behind off Kemp and then Peterson took a return catch to get rid of night watchman Friedel de Wet. The Dolphins finished the day on 131/4 for an overall deficit of 206. Khan is unbeaten on 55 (153 balls, 10 fours) and will have a key role in getting his side close to the Cobras’ total along with his vice-captain, Daryn Smit.Robbie Frylinck (3/78) was the most successful bowler in the Cobras’ first innings and his second wicket was his 100th overall in first-class competition.Meanwhile, the Highveld Lions are in an even stronger position against the Warriors at the Wanderers Stadium, having piled up an impressive total of 511 and then taken five visiting wickets for 115 runs for an overall lead of 396 runs.Neil McKenzie completed his 43rd first-class century (170 off 298 balls, 20 fours and a six) and shared a partnership of 135 for the sixth wicket with Thami Tsolekile who made his third successive score of more than 50 (75 off 120 balls, 11 fours).The Warriors made a dreadful start to their reply, losing three wickets for 19 runs, and much will depend on the ability of Ashwell Prince to rally the remaining batsmen around him. So far he has made an unbeaten 54 (90 balls, 6 fours).Cliffie Deacon has been the standout bowler for the Lions (3/24 in 11 overs).
