MIAMI — The Pittsburgh Pirates have signed right-handers Blaine Boyer and Brett Sinkbeil to minor league contracts.

Boyer has appeared with three major league clubs, most recently the New York Mets, for whom he was 0-2 with a 10.80 ERA in 6 2-3 innings this season. Boyer refused a minor league assignment from the Mets last week, becoming a free agent.

Sinkbeil was a former first-round pick by the Florida Marlins, with whom he played three games last year.

The Pirates also sent left-hander Garrett Olson to Triple-A Indianapolis on Wednesday.
