Balfour is 36 years old, but based on his performance as the A’s closer during the past two seasons he’s likely to be an upgrade over Jim Johnson in the ninth-inning role. This year Balfour saved 38 games with a 2.59 ERA and 10.3 strikeouts per nine innings, holding opponents to a .206 batting average.
Johnson racked up 50-plus saves in back-to-back seasons, but if the Orioles give Balfour that many save chances he’ll do that too. And probably with a lot more strikeouts and a lot less fan anxiety.
UPDATE: Roch Kubatko of MASNSports.com says the two-year deal is worth $14 million.
