This is another infamous Jose story. When John Kucharo was a top 15 ranked player in the world Jose spotted him the 7,8, and 9 on a tight 4 in pocket table and beat him a 10 ahead set for the cash. Soon after this John retired from professional pool, some said he just couldn't believe at his level that someone could spot him that much weight and get there!!
I heard this story from Jose himself. He said the game was 7,8,9 & the break 15 ahead on a very tight table. Jose said he liked the game because John was a big breaker and Jose thought that his forearm would tighten up from breaking hard game after game. Jose said he lost the first 10 games in a row and his backer got very nervous. He said he only lost a handful of games after that and won the set very quickly after that.
I don't think Kucharo was close to top 15 in the world though. He did play very strong though. He finished 5th in the US open one year around that time.
