Ben Cox (England)
Season: 2017-18.
Record: Eight T20 games, 151 runs at 30.20.
The oil: Quality wicketkeeper but do you really need a top-drawer gloveman in T20?
Verdict: Not a good fit, really. Six out of 10.
Ben Raine (England)
Season: 2018-19.
Record: Four T20 games, 60 runs at 30.00, two wickets at 60.50.
The oil: The big-hitting all-rounder arrived late and may as well have left early. Got clobbered for 121 runs at more than 12.10 runs per over.
Verdict: Probably needed a longer stretch to adjust to the conditions. Three out of 10.
Tom Beaton (Australia)
Season: 2016-17.
Record: Two T20 games, 18 runs at 9.
The oil: Came in as a temporary replacement for two matches in Alexandra during the holiday period. He made a golden duck in the first and holed out for 18 in the second.
Verdict: A long-odds punt who came in near the back of the field. Two out of 10.
Dirk Nannes (Australia)
Season: 2014-15
Record: Eight T20 games. seven wickets at 45.
The oil: The former Australian fast bowler was past his prime. Still had a run-up longer than Waqar Younis but was about as express as Gavin Larsen.
Verdict: Got smashed. Two out of 10.
Ryan ten Doeschate (South Africa/Netherlands)
Seasons: 2012-13 to 2014-15
Record: 33 T20 games, 1074 runs at 41.30, 15 wickets at 29.93
The oil: Dragged Otago through to a title in 2012-13 with some tremendous batting in the clutch. Could hit anything to cow.
Verdict: He is still playing aged 39. Sign him up. Nine out of 10.
Jason Holder (West Indies)
Season: 2013-14
Record: One T20 game, 5 runs, two for 38
The oil: Was a ring-in for the final, displacing Neil Wagner. He bowled, batted and fielded poorly. And Otago lost.
Verdict: Great player. Has gone on to captain the West Indies. It was not his night, though. Four out of 10.
Brett Lee (Australia)
Season: 2012-13
Record: One T20 game, 1 not out, one for 19
Oil: Flew over for one match on the promise he would be available for the Champions League. The fast bowler ended up backing out of that agreement.
Verdict: It was quite surreal watching him run in for Otago. Impressive player. Impressive man. And he drew a crowd. Eight out of 10.
Dimitri Mascarenhas (England)
Seasons: 2008-09 and 2011-12
Record: 17 T20 games, 300 runs at 21.42, 12 wickets at 32.33
The oil: Helped Otago win the title in 2008-09 with some hard hitting in the middle and some useful wickets. Went on to coach the side for one season.
Verdict: Very handy T20 player. Terrible coach. Seven out of 10.
Darren Stevens (England)
Season: 2010-11
Record: Seven T20 games, 102 runs at 17, 3 wickets at 53.33
The oil: Famous for taking a nap while waiting to bat. Thereafter referred to as the narcoleptic trundler.
Verdict: Enjoyed the social aspects of life too much perhaps? Two out of 10.
Chris Nash (England)
Season: 2010-11
Record: Seven T20 games, 32 runs at 6.40, six wickets at 21.16
The oil: Actually bowled quite well during the campaign.
Verdict:The better of the two English duds that year. Five out of 10.
Yasir Arafat (Pakistan)
Season: 2009-10
Record: Eight T20 games, 13 runs at 4.33, 8 wickets at 23.25
The oil: The Pakistan all-rounder ran hot and cold. Could be quite devastating one minute and very average the next.
Verdict: Was a decade ago now but perhaps six out of 10.
