"[General manager] Theo [Epstein] visited with him [Tuesday] a little bit," manager Terry Francona said. "Obviously, [Miller] is a huge part of our organization, and it's going to stay that way. He's not going anywhere."
The left-hander, who is 3-3 with a 2.47 ERA this season at Triple-A Pawtucket, had the option to become a free agent Wednesday. However, his decision to stay put could pay off. A Major League source said Miller is expected to receive a start on Boston's next homestand, which begins Friday.
The last time the 6-foot-7 pitcher started a game in the Major Leagues was in 2010 for the Marlins. He pitched 32 2/3 innings that season and finished with an 8.54 ERA and a 1-5 record.
If Miller is called up to start for the Red Sox, a six-man rotation is possible with an already solid starting staff in place.
Still, there are steps the organization must take before Miller can make an appearance in the Majors.
"I think as things unfold here, it will make sense," Francona said. "We can't get ahead of ourselves."
