One of the pitchers most connected to the Red Sox this winter, Corey Kluber, signed with the Yankees on Friday, which at least from the outside added a bit more urgency to the team’s search for starting pitching help. According to reports, they have indeed added a pitcher today, though it’s not one of the top ones on the market. Instead, it’s running it back with one of the few pitchers who didn’t totally implode from last year’s staff. According to Ken Rosenthal, Boston is close to a one-year deal with Martín Pérez with a team option for a second year.
