My late, Scottish mother had a very pertinent saying: “If you sleep with a dog, you’ll wake up with fleas.” It seems appropriate today, as MLB - now partnering with all manner of sports books and gambling enterprises - has dropped the hammer on a number of players who were found to be betting on baseball games. The biggest punishment was meted out to Padres infielder Tucupita Marcano, who received a lifetime ban, and became the first active player to be banned for gambling in a century. He wasn’t even very good at it, winning just 4.3% of bets.
