Chester’s Porcello to disabled list, not Yankee Stadium mound

Staff and wire reports

BOSTON – The Red Sox have placed struggling right-hander Rick Porcello on the 15-day disabled list because of soreness in his right triceps.

To fill his spot on the roster, Boston added newly acquired right-handed reliever Ryan Cook.

Manager John Farrell said Sunday the Red Sox initially thought of just pushing Porcello’s next outing back. He was scheduled to start at Yankee Stadium on Tuesday, the start of a three-game series.

The Red Sox still haven’t named a replacement starter.

This is Porcello’s first trip to the DL in his seventh full professional season.

“We feel like it’s a short-term thing,” Farrell added.

The 26-year-old Porcello, who grew up in Chester and now spends off-seasons in Tewksbury, was expected to be a top-of-the rotation starter, but he is 5-11 with a 5.81 ERA in 20 starts, third-worst among qualified major league starters. In his last nine starts, he has allowed 35 earned runs over 44 2/3 innings.

Boston acquired Porcello from Detroit during the offseason, and signed him to a four-year, $82.5 million contract extension in April.

Boston acquired Cook from Oakland at the non-waiver trade deadline Friday in a deal for a player to be named or cash. He was pitching for the Athletics’ Triple-A affiliate.
