The Pittsburgh Pirates today appointed right-handed pitcher Daulton Jefferies as their additional player for the second game of today’s doubleheader against Detroit.

The 28-year-old Jefferies began the year in the Giants organization, where he made two appearances (one start) with San Francisco while also going 1-0 with a 3.44 ERA (18.1ip/7er) in four appearances (two starts) with Triple-A Sacramento.

Jefferies was acquired by the Pirates organization on May 10 in exchange for minor league outfielder Rodolfo Nolasco and assigned to Triple-A Indianapolis, where he has made two starts.

Jefferies will wear uniform No. 59.
