In double-dose of bad news, SF Giants lose Robbie Ray and series to Mariners

When the Giants traded away Alex Cobb and Farhan Zaidi declared their starting rotation the best in baseball, they were betting the five-man group as assembled could carry them the eight weeks from the trade deadline to the last day of the regular season and, they hoped, into October.

It was a risky wager, with a pair of rookies and another coming off major surgery, and the chances of it paying off took another blow when Robbie Ray winced and grabbed at his left hamstring on his 62nd pitch Sunday afternoon at T-Mobile Park.
