Outlook: Solid Cook unlikely to see many save chances

PHOENIX -- Ryan Cook is progressing just as the A's would like, but it remains uncertain whether the righty setup man will be ready for Opening Day.

Cook has no doubt he will be, but manager Bob Melvin admitted on Monday, "It's going to be close. We still hold out hope."

On the mend from shoulder inflammation, Cook is scheduled to throw in his first bullpen session of the spring on Thursday. He'll need a handful of those under his belt before facing hitters. This means he's likely not targeted for an exhibition game for at least another two weeks, with only two more weeks remaining thereafter on the preseason schedule.

Cook appeared in nine Spring Training games last year, and though Melvin wouldn't put a number on how many he'd like to get the reliever this time, ideally it's five or six -- including back-to-back days.

"It depends how he does each and every time," said Melvin. "Whether or not we need a back-to-back, I'm not sure yet, but it'll be down to the wire probably."

The A's have more than enough depth to withstand Cook's potential absence from the Opening Day roster, but that doesn't alter their desire to have him on board right away.

"We haven't rushed it to this point," Melvin said. "We've been really careful with him. He's been feeling great for a while now. But, as far as our programs go, he's going through the regular process. So certainly the depth is a consideration, but we'd like to have him for Opening Day."

Oakland loses Parrino to Texas' waiver claim

DET@OAK: Parrino robs Hunter with diving stop

PHOENIX -- The A's lost infielder Andy Parrino to the American League West-rival Rangers via waivers on Monday.

The move came four days after he was designated for assignment by the A's after they acquired infielder Jake Elmore from the White Sox for cash.

Parrino's time in the A's organization was short-lived. Originally acquired by the club with hurler Andrew Werner from San Diego for righty Tyson Ross at the end of 2012, Parrino had a pair of stints with the A's last year but appeared in only 14 games, hitting .118 in that span.

He spent the balance of the season with Triple-A Sacramento, where he hit .210 with a .602 OPS in 108 games.

Monday's transaction brought to mind the last time an A's player was claimed by the Rangers. Adam Rosales was designated four times in 13 days in the second half last year, claimed twice by the Rangers and once by his original team. He's since stuck with Texas.

"Yeah," said manager Bob Melvin, smiling, "this kind of has that Rosie feel to it, but we'll see. Good for [Parrino]. We would've loved to have him back, but certainly for a guy to be put on their roster in that fashion, it's good for him."
