All-Star OF Melky Cabrera of the Giants receives a 50-game suspension for testing positive for PEDS

All-Star OF Melky Cabrera of the Giants sees his outstanding season come to a crashing end with a 50-game suspension for testing positive for testosterone, a performance-enhancing drug. Cabrera is hitting .346 with a league-leading 159 hits, but will not be eligible to return to play this year unless the Giants make it to the second round of the postseason; the Giants will indeed make it all the way to the World Series, but will have cut off all remaining ties with their disgraced star by then. Without Cabrera, the Giants lose, 6 – 4, to the Nationals and fall out of first place in the NL West when the Dodgers defeat Pittsburgh, 9 – 3.
