The New York Yankees are crossing their fingers today and hoping for good news about the condition of reliever David Robertson, who injured his right foot in a fall Wednesday. Reports indicate that initial tests show “some cause for concern,” according to manager Joe Girardi.

Results of more tests are expected to be available Friday, at which time the Yankees should know how long they will be without Robertson, who pitched to a 1.08 ERA in 2011 and made the All-Star Team as a setup man for Mariano Rivera.

If the Yankees are without Robertson for any length of time that puts pressure on Rafael Soriano, who had a disappointing first season in New York in 2011 after signing a three-year, $35-million contract. Soriano was expected to be the Yankees’ eighth-inning reliever, but injuries and inconsistency opened the door for Robertson.

Now — pardon the pun — the shoe might be on the other foot.
