GOODYEAR, Ariz. — The A's pitching corps has been shaken the last few days with the news that A.J. Griffin had to be shut down for three weeks by elbow pain, then that fellow starter Jarrod Parker is out for the year needing Tommy John ligament replacement surgery.
On Wednesday there was some good news.
Reliever Ryan Cook faced hitters on the back field at Phoenix Municipal Stadium, threw all his pitches without any discomfort in his previously ailing right shoulder and said he still hopes to be ready for opening day.
Scott Kazmir, scratched from a start Monday, threw a 35-pitch bullpen, also in Phoenix, and seems to be unimpaired by the triceps discomfort that led to him being kept off the mound. He's due to start Saturday against the Mariners, the same game in which Cook hopes to relieve.
And on offense, Josh Donaldson played in the A's 13-3 win over the Cleveland Indians for the first time since leaving Sunday's game with a bit of calf tightness.
Donaldson singled once in four at-bats. Through it all, he moved on offense and on defense as if he wasn't feeling any calf backlash.
After throwing his session, Cook predicted he'll pitch in his first game of the spring Saturday.
"That's just me talking," he said shortly after walking off the back mound at Phoenix Municipal Stadium all smiles. "The arm isn't a consideration any more.
"It's about me getting game-ready."
When he was finished throwing, Cook told pitching coach Curt Young he felt "game-ready."
