The Boston Red Sox are reportedly close to naming a new pitching coach, as the organization has narrowed the list down to four finalists: Rick Peterson, Randy St. Claire, Juan Nieves and Steve Foster.

Peterson, a former pitching coach of the Oakland Athletics, New York Mets and Milwaukee Brewers, is the favorite to land the job. Peterson was fired at all three of his previous stops and spent the 2012 season as the Baltimore Orioles director of pitching development, a position that places him responsible for developing young arms.

St. Claire spent seven seasons as the Washington Nationals pitching coach before being fired in '09. St. Claire was the Miami Marlins pitching coach in '12.

Nieves is the Chicago White Sox bullpen coach while Foster is the Kansas City Royals bullpen coach and special assistant to general manager.

A source told WEEI's Alex Speier the Red Sox will make a decision on the pitching coach sometime this week.
