A San Francisco Giants minor leaguer called Fernando Tatis Jr. a "cheater" on Twitter after the suspended San Diego Padres superstar hit a mammoth home run Wednesday night in a Triple-A game while on a rehab assignment. Kade McClure of the Sacramento River Cats responded to a tweet that included video of the homer at Sacramento's Sutter Health Park by saying, "cheater hits a homerun on a rehab assignment during a steroid suspension."
