Two days after turning in what by far was his best outing of the young season, CC Sabathia landed on the disabled list.

The Yankees announced Friday afternoon the 35-year-old lefthander, 2-2 with a 3.81 ERA over five starts, was placed on the 15-day DL with a left groin strain.

Lefty reliever Phil Coke, who signed a minor league deal with the Yankees on April 25, was called up from Triple-A Scranton/Wilkes-Barre. Coke, a 26th-round draft pick in 2002, pitched for the Yankees from 2008-09 before being traded in the three-team deal that netted them Curtis Granderson from the Detroit Tigers.

There were no signs — none that were obvious, at any rate — that Sabathia had been in any discomfort.

Sabathia was one of the few bright spots for the Yankees on their recent 2-7 trip, throwing seven shutout innings against the Orioles at Camden Yards in a 7-0 victory. The outing was the longest of the season for the pitcher.

It was not immediately clear who would take Sabathia’s spot in the rotation. Ivan Nova, who lost the fifth starter battle to Sabathia in spring training, is a strong possibility, but two pitchers currently throwing well in Triple-A, Luis Cessa and Chad Green, are also options.
