The Boston Red Sox begin a pivotal 10-game homestand Friday night, and they’ll do so without David Price.

The Red Sox left-hander was scratched from his scheduled start Friday night against the Kansas City Royals with an arm issue, the team announced. Boston placed the lefty on the 10-day disabled list retroactive to July 25 with elbow inflammation. Rick Porcello will start the series opener on four days’ rest, with Eduardo Rodriguez and Drew Pomeranz pitching Saturday and Sunday, respectively.

Price missed nearly two months to start the season after experiencing tightness in his forearm during spring training. He underwent an MRI on the arm Thursday, ESPN’s Buster Olney reported Friday.

The southpaw was rocked in his last start, allowing six runs (five earned) — on seven hits in just five innings against the Los Angeles Angels of Anaheim. Price had been pitching better before that, however, lowering his ERA nearly two whole runs after that mark ballooned to 5.29 in early June.

In the three starts before his outing against the Angels, Price allowed just two runs over 20 innings, striking out 22 and walking just four. It was the best he’s looked in a Red Sox uniform since signing a seven-year, $217 million contract last offseason.

Boston recalled left-handed reliever Robby Scott from Triple-A Pawtucket in a corresponding move for Price.
