Arroyo "is our second baseman as of now," Red Sox manager Alex Cora told Christopher Smith of The Springfield Republican Tuesday.
Adalberto Mondesi (knee) will be a candidate to start at second base once he's ready, but he'll be behind others at the start of spring training. Arroyo sports a solid .273/.320/.427 batting line with 15 home runs over 158 games during his two-and-a-half years with the Red Sox. He might ultimately be just a placeholder for Mondesi but we've learned over the years that Mondesi is no sure thing to play or perform.
