The Athletics recalled Rom from Triple-A Las Vegas on Wednesday.
After claiming Rom off waivers from the Brewers on Tuesday, the Athletics could have stashed the lefty at Triple-A Las Vegas, but he'll report to the big club right away and provide a fresh arm out of the bullpen. Rom -- who struck out 11 batters and allowed two earned runs on six hits and four walks in 5.2 frames with the Brewers this season -- is likely to serve as a multi-inning reliever for the Athletics.
