Pregame notes: Youk, Mo, Pronk

Although it often seems that the main activity around the Yankees is injuries, occasionally interrupted by baseball games, the reverse is actually true. Although both Ivan Nova and Francisco Cervelli were injured Friday night and landed on the DL, Saturday's game against the Toronto Blue Jays is still the main event.

Here's what's happening away from the hospital ward:

Kevin Youkilis is back in the lineup after missing six games with soreness in his lower back. On Saturday morning, Joe Girardi said Youkilis' presence in the lineup was conditional on him coming through batting practice OK. Evidently he did, because he is still in the lineup -- and for his part, Youkilis insisted his return to the field Saturday was never in doubt. Of course, he had said the same thing before each of the six games he missed.

• Girardi said he was leaning towards not using Mariano Rivera. The 43-year-old, who is 8-for-8 in save chances this season, has pitched in two of the Yankees' past three games -- allowing a home run Wednesday in Tampa and three hits in the ninth inning of Friday night's 6-4 win, although he escaped allowing a run thanks to two strikeouts to end the game.

Travis Hafner is getting a rare start at DH against a left-handed starter, J.A. Happ, who he has never faced. Hafner's right-handed hitting counterpart, Ben Francisco, is struggling -- he is batting .103 this season -- and has just one single in six lifetime at-bats against Happ.

CC Sabathia, Saturday's starter, is 8-1 with a 2.49 ERA in his past 10 starts against the Blue Jays. The last time he faced them, however, Sabathia took the loss in an 8-5 Yankees defeat here last Aug. 29.

• It's only bookkeeping, but the Yankees moved Derek Jeter to the 60-day DL to clear roster space for the players who were called up to replace Nova and Cervelli, Austin Romine and Vidal Nuno.
