Luis Ayala set to join Orioles

The Baltimore Orioles continued their efforts to reinforce their bullpen Friday, closing in on a one-year contract with free-agent right-hander Luis Ayala, according to a major-league source.

The deal also might include a club option, the source said.

Ayala, 34, rebounded with the New York Yankees last season, going 2-2 with a 2.09 ERA in 52 appearances. Both the Los Angeles Dodgers and Arizona Diamondbacks released him in 2010.

The Orioles added another right-handed reliever, Matt Lindstrom, in a trade with the Colorado Rockies earlier in the week.
