“The information that this guy from Grand Slam Picks told me was incredible. He told me that the team had a huge fight in the clubhouse, and take the other side of the game which was +170 game. Wow was he right. The team never scored a run. Now that’s great inside information.”

“Grand Slam Picks was introduced to me when I was at the craps table at the MGM Grand in Vegas. A gentleman said that he won a huge amount of money. When I ask where they are located etc. he said just call them and ask for Vincenzo. Ever since I called Vincenzo from the first day, he has made me money. Thanks Vincenzo!!!”
