The Orioles and right-hander Darren O'Day on Monday hashed out the final details on a four-year, $31 million deal that will keep the popular, side-arming reliever under club control through the 2019 season, according to an industry source.
The deal is expected to be announced after O'Day completes a physical, which had not yet been set up.
News of O'Day's potential deal was leaked Sunday morning, but there were still significant contractual stipulations that had to be worked out – and neither side was willing to pronounce that the deal was completed.
Those issues were finalized Monday evening in Nashville, a source said.
O'Day, 33, was arguably the best reliever on the open market this offseason after recording four consecutive years of sub-2.00 ERAs while making at least 68 appearances each season for the Orioles.
He was close to signing with the Washington Nationals on Friday night for a three-year deal with an option, but the Orioles jumped in at the 11th hour and offered a fourth year. He would have received more money annually from the Nationals, but the extra year was the difference-maker. The new contract also contains some limited no-trade protection.
