Yankees have placed closer David Robertson on the 15-day DL with a Grade 1 groin strain, the manager announced to the media after the team's 4-2 victory over the Baltimore Orioles on Monday afternoon at Yankee Stadium.

Robertson has only appeared in three games for the Yankees so far this season, as his tenure as Mariano Rivera's replacement didn't last very long.

With the Yankees up 4-2 in the 9th Monday, Girardi gave Shawn Kelley to ball to pitch the 9th, and he set the Orioles down in order for the first save of his big league career. Girardi mentioned that Kelley will be the closer moving forward with Robertson on the DL.

Robertson has been one of the game's best late-inning relievers over the past couple of seasons, and this is obviously a tough loss for the Yankees just seven games into the season, especially after putting Mark Teixeira on the DL with a hamstring strain on Sunday.

A Grade 1 strain is what the MRI showed today, and of course the best news would be no injury at all, but Grade 1 strains aren't that serious, but we can only hope that Robertson is ready to get back on the mound in a game 15 days from now.
