Really unfortunate for Otago that two batsmen had to retire hurt. First Rutherford after being sconed, and he was going great guns too, then Foxcroft who was also going along nicely but got absolutely nailed in a classic SBW shoulder charge. The latter returned but the two retirements hurt Otago, cost them runs and possibly the game.
This incident also begs the question of whether your 12th man should be able to contribute with both bat and ball, or possibly should they simply be a batsman given you're most likely to lose a batter. Of course, the injured batsman may actually be a bowler, hence perhaps having an AR as 12th man. Then if you lose two permanently (extremely rare, yes, but almost happened today) should there actually be two players available to step in?
