Chris Gayle hits fastest century in cricket history He eventually finished on 175 not out, the highest T20 score ever, off 66 deliveries, which included 13 fours and 17 sixes at a strike rate of 265.15. Gayle's knock has already been described as "the 501 of Twenty20 Cricket" - Brian Lara's record-breaking innings while playing for Warwickshire. At the end of innings, Gayle said: "I'm astonished myself. I think we've got a good total. Hopefully I can run around now and take a few catches.
