Ok interesting, the reasoning behind the Red Card:
==
Sunil Narine, the Trinbago Knight Riders spinner, became the first cricketer to receive a red card on Sunday, during a Caribbean Premier League (CPL) match.
This was after the organisers of CPL, in a bid to combat slow over-rates, introduced the system of red card to ensure teams are bowling their quota of overs in the mandated 85 minutes and not lag behind schedule at the start of the final over of an innings.
The sanction means a team loses a player selected by the captain and must have six fielders inside the circle.
Thereafter the Knight Riders were left with 10 men for the final over their match against the St Kitts & Nevis Patriots. However, they still won the match by six wickets.
Incidentally, Narine had completed his quota of four overs by then before he was withdrawn for the last over.
TKR Skipper Kieron Pollard expressed his unhappiness with the penalty and said, “To be honest, it will take away the hard work everyone has done,” he said. “We are like the pawns and we are going to do what we are told.
“We are going to play as fast as we can. If you are penalised for 30-45 seconds in a tournament like this, it is absolutely ridiculous.”
An extensive list of penalties has been drawn up in the tournament-
If behind the required over rate at the start of the 18th over, one additional player must enter the fielding circle (for a total of 5)
If still behind the rate at the start of the 19th over, two additional fielders must enter the fielding circle (for a total of 6)
If still behind the rate at the start of the 20th over, teams will lose a player from the field (selected by the captain) and have six inside the fielding circle.
There will also be an onus on batting teams to keep the game moving.
Sunil Narine had completed his quota of four overs, with figures of 24-3, before he was withdrawn for the final over of the Patriots' innings, which yielded 18 runs.
