The Red Sox have been “contacted by Major League Baseball and are fully cooperating with their investigation” into the Astros’ alleged electronic sign-stealing in 2017, team president and CEO Sam Kennedy confirmed in an email Friday morning.

The league is looking into Houston’s practices after a Tuesday report from The Athletic cited four sources -- including former Astros pitcher Mike Fiers -- who alleged Houston used a center-field camera to steal signs from opposing catchers in 2017. The Athletic later reported that the league planned to interview Red Sox manager Alex Cora, who was Houston’s bench coach in 2017, as part of the investigation.

ESPN’s Jeff Passan reported Wednesday that the league had contacted members of the Red Sox organization, including Cora and bullpen coach Craig Bjornson, who was also on Houston’s staff in 2017. The league office appears to be in the early stages of a widespread investigation into the matter.

Reached Wednesday, Cora said: “Given there is an MLB investigation into the 2017 Astros, it is best for me not to comment.” Appearing on WEEI’s Dale & Keefe, Cora confirmed he had spoken with Major League Baseball but declined further comment.

According to reports, Major League Baseball is expected to interview a wide range of subjects, including Astros manager A.J. Hinch, Mets manager Carlos Beltran (who played for Houston in 2017) and former Astros assistant general manager Brandon Taubman.
