Athletics assistant general manager David Forst refuted a report last week that right-handed starter A.J. Griffin was headed for season-ending Tommy John surgery. But there’s no more refuting it now.
Griffin was shut down in the middle of spring camp with right elbow discomfort and later got diagnosed with a flexor muscle strain. He will now be sidelined through at least the first month of the 2015 season.
Griffin, 26, owns a 3.60 ERA and 1.126 WHIP in 282 1/3 career major league innings.
The A’s also lost Jarrod Parker to Tommy John surgery earlier this season.
