Yanks having to manage 'pen workload

Yanks having to manage 'pen workload

NEW YORK -- With the Yankees involved in tight games and a tight race for the American League East title, the business end of their bullpen has received plenty of work recently. With those innings comes subsequent unavailability for many of their relievers.

One day after David Robertson stayed in the bullpen with general soreness, manager Joe Girardi said he likely did not have Mariano Rivera or Rafael Soriano available for Saturday's game against Toronto.

The Yankees have won five of six games, and Rivera has earned the save in each of the team's last four victories. Soriano had also pitched on four of the last five days entering Saturday. Since returning from the disabled list on July 30, he has struck out 12 in 12 2/3 innings and pitched to a 2.84 ERA.

Robertson has been invaluable to the Yankees this season, but the Yankees have been careful not to overwork him. His 58 appearances are tied for 45th in the Major Leagues. In 2010, the 26-year-old right-hander pitched in a career-high 64 games.

"I'm trying to regulate it like we do with a lot of our relievers and not try to work him too much," Girardi said of Robertson. "Sometimes a guy just needs a day. Sometimes the inning that you go through you work really hard, and for whatever reason, you might be a little stiff the next day."
