The Sox had listed Franklin Morales as Wednesday's starter for the final game of the road trip, but have re-arranged their rotation.
Aaron Cook, who tossed an 81-pitch complete game shutout Friday, will pitch Wednesday afternoon.
For the four-game set with the Yankees at Fenway beginning Friday, the Sox will start Josh Beckett in the series opener, lefties Morales and Felix Doubront in the day-night doubleheader Saturday, with Jon Lester pitching the finale Sunday night.
Morales, meanwhile, will be starting on eight days rest and will be available out of the bullpen Tuesday night and Wednesday afternoon.
"We're trying to make the best use of what we have,'' Valentine said.
Major league manager. Inventor of the wrap sandwich. Champion ballroom dancer. And…
US ambassador to Japan?
Bobby Valentine is on the short list for that position in President Donald Trump’s administration, according to a WEEI.com report.
The former Red Sox manager (fired after a 69-93 season and last-place finish in 2012), and ex-New York Mets and Texas Rangers, skipper, also managed the Chiba Lotte Marines in Japan’s Pacific League for six seasons.
Valentine, 66, has known the President-elect and Trump's brother Bob since the 1980s, is close to others on Trump’s transition team and has had preliminary discussions about the ambassador position, according to WEEI.com’s Rob Bradford.
Valentine, currently the athletic director of Sacred Heart University in Fairfield, Conn., is also friendly with current Japanese Prime Minister Shinzo Abe, who, like Valentine, attended the University of Southern California.
The Pablo Sandoval redemption tour is underway as the former World Series MVP tries to revive his career after two disastrous seasons with the Red Sox organization.
In an interview with ESPN Deportes, he admits to being “complacent” during his first two seasons in Boston after signing a five-year, $95 million deal.
"My career had fallen into an abyss because I was so complacent with things that I had already accomplished," Sandoval said. "I did not work hard in order to achieve more and to remain at the level of the player that I am and that I can be."
After dealing Travis Shaw to the Brewers, Sandoval is expected to be the Red Sox primary third baseman in 2017.
"I am not taking anything for granted," he said. "I am here to work hard. I'm not thinking about the position or not. I am starting from scratch, and I am here to show what I can do on the field."
The 30-year-old says he’s following a “really strict routine” this offseason, and it shows. In a recent photo, Sandoval appears noticeably thinner. Sandoval says his wife giving birth to “Baby Panda” has served as inspiration.
"Watching 'Baby Panda' grow up and that he gets the opportunity to see his father play in the majors for seven, eight more years, to get back to the success I had, that's my motivation every day," Sandoval said. "The people that I surround myself with now and my family, they are the key to my success. This has been a life lesson."
