(NEW YORK) -- After having stability at the closer position for nearly two decades with Mariano Rivers, the New York Yankees find themselves scrambling as closer David Roberston was placed on the disabled list with a groin strain.
Robertson was the heir-apparent to Rivera, who spent 17 seasons with the team before retiring following the 2013 season. He was the set-up man behind Rivera for three seasons and the team felt confident having him close full-time.
"Well, it's not what you want, but you gotta figure it out," Yankees manager Joe Girardi said. "We've had to deal with this before and other guys will have to step up in his absence."
It is unknown who will replace Robertson as the team's closer, but the team is expected to go with the closer-by-committee route.
Girardi said he may rotate Shawn Kelley, Adam Waren, David Phelps, and Dellin Bestances.
The 28-year-old Robertson is in his seventh season with the Yankees, and has a career ERA of 2.71.
