BALTIMORE -- Jeff Gray was in the midst of the Triple-A playoffs when he got the call he'd been waiting for -- despite perhaps not expecting -- for most of his adult life. On Friday, Gray made the seven-hour trek across the country to join the A's in Baltimore, the first Major League callup of the right-hander's career.

Gray is the third pitcher the A's have called up since rosters were able to be expanded on Sept. 1. The 26-year-old is a power pitcher who has worked in all facets of relief for the Sacramento RiverCats. He joins Dan Meyer and Josh Outman, the other two pitchers recalled, on the Major League pitching staff.

"I was planning on calling him up when their playoffs were over in Triple-A," manager Bob Geren said, with the RiverCats at 1-1 in a best-of-five series with Salt Lake. "But with two games yesterday and a doubleheader tomorrow I just wanted him now. He's got a good arm, he throws mid-90s. We've got a lot of young guys that are in the mix."

The move was largely necessitated by the A's having to play two doubleheaders in a two-day span -- the last a two-game sweep at the hands of the Royals on Thursday -- and a scheduled twin bill on Saturday with the Orioles.

Nonetheless, Gray, who Geren said the A's had been keeping a close eye on at Triple-A, was just happy to be on the big league roster.

"I had no idea at all," Gray said. "I was hoping that I would get a call up, but I wasn't really expecting it. ... I flew at six this morning and I got here at about 4 p.m., had a layover in Salt Lake -- so it's been a while, but it's been an exciting while."

The A's have not yet defined a role out of the bullpen for Gray.
