The Red Sox are calling up heralded infield prospect Marcelo Mayer from Triple A Worcester. WooSox manager Chad Tracy told reporters in Worcester on Saturday that he’d delivered the news to the 22-year-old, whom Baseball America recently ranked as the game’s No. 9 prospect, before the team’s doubleheader at Polar Park.

Marcelo Mayer, Boston's No. 2 overall prospect, was promoted to the Red Sox and needed to get a ride to Fenway Park to start against the Baltimore Orioles on Saturday.

Marcelo Mayer got the news Saturday between games of Triple-A Worcester’s home doubleheader against Durham. The news that every Minor Leaguer dreams about: He was being promoted to the Major Leagues.

Mayer talked days before his callup about how he woke up every day imagining what it would be like to get called up. He no longer had to wonder.
