With a pair of off-days scheduled this week, the Pirates will skip Vance Worley's turn in the rotation, MLB.com reports.
Francisco Liriano and Jeff Locke will square off with the Twins during a two-game series Tuesday and Wednesday before the team hosts the Mets for a three-game series this weekend. Worley is 2-3 with a 4.38 ERA and 23:14 K:BB ratio in 39 innings.
