Before the New York Yankees began their four-game set with the Oakland Athletics, they made a plethora of roster moves regarding the rotation.

In the wake of CC Sabathia‘s hamstring injury, the New York Yankees announced on Thursday that they have shuffled their rotation with a couple of roster moves.

Firstly, the veteran left-hander was placed on the 10-day disabled list with a Grade-2 left hamstring strain. While it’s not confirmed how much time he’ll miss, his injury could cost Sabathia, who owns a 0.99 ERA in six starts since May 16, about a month.

New York also optioned RHP Ronald Herrera, who surrendered a home run to Angels’ shortstop Andrelton Simmons in his Major League debut on Wednesday, to Double-A Trenton. To fill the spots on the roster, Luis Cessa and Domingo German have been recalled from Triple-A Scranton/Wilkes-Barre.

Cessa appeared in 17 games (nine starts) last season for the Yankees and posted a 4.35 ERA and surrendered 16 home runs in 70.1 innings of work. The 25-year-old has also made 10 starts for the RailRiders this season and is 2-6 with a 4.27 ERA.

Finally, first baseman Greg Bird has returned from his rehab assignment with right knee contusion. General manager Brian Cashman told Erik Boland of Newsday that Bird still doesn’t feel well, so they “pulled the plug” on his rehab.

The lefty has been out since early May with a bone bruise in the ankle and a completely separate injury can’t help. He was hitting .143/.357/.238 in Triple-A while the Yankees own the second-worst WAR (-1.0) from the position in 2017.
