OF Craig Gentry, the Athletics' new backup outfielder, was declared out for an additional week and a half. Gentry was expected to miss only a few days after incurring a lower back strain the first week of camp. Manager Bob Melvin said Gentry is still expected to be ready for the start of the season.
RHP Ryan Cook (right shoulder tightness) is considered questionable for the Opening Day roster, according to manager Bob Melvin. Cook is scheduled to throw his first bullpen session of the spring on March 6, and he wouldn't appear in a spring game for at least a week or so after that.
INF Jake Elmore was acquired by the A's from the White Sox in a cash deal on Feb. 27. Elmore, 26, fits Oakland's versatility mode -- he played every position, including catcher and pitcher, for Houston last year. He has two options left and is unlikely to be an immediate big-league option for Oakland.
OF Billy Burns, acquired from the Nationals for LHP Jerry Blevins in December, is making a good impression in camp. The switch-hitting speedster is not known for having a good arm, but he threw out two runners in a game on March 2 and he hit .313 with five steals in his first six spring games. Burns is a strong candidate to be a September call-up, but he could be an option sooner in the event of injury.
