Calcaveccia told Golf.com, "I didn't really think about it, but in the course of last year he changed his number five times." He added, "The last time he did, I said, 'Man, you change phone numbers more than I change underwear.'"
Calcaveccia claims he and Tiger used to text message each other all the time back before the scandal broke -- but he hasn't heard back from Tiger since the infamous car crash.
There was one more interesting point -- Mark told the magazine, "I did know of a girl he was seeing in Phoenix ... But I didn't know the time frame." Mark concluded, "I didn't know if it was before or after he was married that he was with her. I knew it was close. It was 2004 sometime. I didn't think much of it then..."
FYI -- Tiger married Elin Noredegren in 2004 -- but they were engaged since 2003.
