Shafer got sick mid-game Friday night and was unavailable to pitch, Shi Davidi of Sportsnet.CA reports.
As a result, Derek Law pitched the last two innings to get the save against the Orioles. Shafer's hold on the closer job, such as it is while Ken Giles (elbow) is out, is pretty tenuous to begin with. As soon as Shafer's available again he'll be an option in the ninth, as will Law and Tim Mayza.
