The case rack of this match has been considered a few times before on the forum. I wondered whether the cue ball, which was frozen to the nine in the case rack, may have been lined up for a dead scratch in the side pocket. Even if that was so, a touch of right masse could have been used to leave the cue ball near the head rail. Defense was available no matter how you slice it. As ridiculous as Mike's shot looked , however, it was not completely without merit, but it wasn't best.
This was not the best match of all time, but among the best comebacks of all time, slightly devalued by the fact that it was decided by a roll. My vote for the greatest comeback of all time is in the final of the 2013 BCAPL 10-ball event at the Rio in Las Vegas. Dennis Orcullo led Rodney Morris 9-2 in the race to 11 final and Dennis was in dead stroke., With some of the finest shooting anyone's ever seen, Rodney completed the comeback to win the title. Also worthy of mention is Efren's comeback at the BCA Championships at the Riviera in Las Vegas circa 1999 --- in an early round hookup, Allen Hopkins had a 10-1 lead on him but Efren won the next ten racks to win the match.
Best nine ball match ever is, in the eyes of many, was the Efren vs Earl race to 120 "Color of Money" match, but if only tournament play is considered, I'd go with when the sixteen year old Wu Jiaqing played Po Cheng Kuo in the final of the World 9-ball title in 2005. In the race to seventeen final, Kuo led 16-12 but went wrong on a safety in the next rack and Wu ran out that rack and broke and ran the next four to claim the world championship.
