Highveld Lions captain Neil McKenzie smashed his second ton of the match on Sunday, but while both sides made declarations on the final day, the visitors played to a draw against the Dolphins in Durban.

McKenzie led from the front after the Dolphins declared their first innings at 477/6 overnight.
The skipper made 101 not out before the Lions made a declaration of their own after tea, at 268/6, to give the hosts an unlikely target of 210 to win with 23 overs remaining in the day.
Proteas spinner Imran Tahir led the Dolphins attack, returning 4/88.
The home side, bottom feeders in the first-class competition, reached 50/1, needing another 160 runs for victory with nine wickets in hand, when stumps were drawn.

Seam bowler Vernon Philander and part-timer Justin Ontong combined well to restrict the Knights line-up.
Hendricks, however, held them together with an 82-run contribution, batting for five hours before he fell after drinks in the final session.
