In the spirit of Jesse Orosco, the Dodgers have turned to an oldster in an attempt to add more lefty strength to their bullpen.

According to Jayson Stark of ESPN.com, Los Angeles has signed Ron Mahay — who will be 40 in June — to a non-roster deal.

Despite the age issues, this is no Merkin Valdez signing. Mahay, who has pitched in 514 career games, allowed only 41 baserunners in 34 innings with Minnesota last season. Against lefties, Mahay gave up 12 singles, a double, a homer and two walks in 68 plate appearances — a .520 OPS.

Mahay will give Scott Elbert, among others, a challenge in Spring Training, and it’s hard to say it’s not justified. It’s been these types of signings that have been among the brightest in general manager Ned Colletti’s tenure — low-risk moves with legitimate chance of reward.

Update: The Dodgers confirmed the signing at 3:30 p.m.
