Red Sox: Who can we expect to see called up in September?

As the calendar gets ready to turn over to September, let’s take a look at the players who might be joining the Boston Red Sox at the end of the month.

September 1st is a big day for the Red Sox and for all teams around the MLB.  September 1st is the day that the MLB rosters expand from 25 to 40 men. That means that the team can call up anyone on their secondary (40 man) roster to their big league ball club.

Now almost no team is going to use all 40 spots but this is a good opportunity to bring up some guys to fill out your roster. Teams can bring up young players and see how they handle playing in the show. The Red Sox did this in 2016 when they added (then) top prospect Yoan Moncada last season.

Moncada, who had started the 2016 season in A ball, struggled over the last month of the season. He slashed .211/.250/.263 in 8 games, and showed that he could not hit big-league breaking balls.

He was basically Pedro Cerrano in Major League, but probably with less voodoo.

Seeing Moncada struggle in September most likely made it easier for the Red Sox brass to make him the corner piece in the Chris Sale trade; one of the many benefits of these roster expansions.

It’s also a team’s last shot to add players to their team in order for them to be eligible for their post-season roster. The Red Sox did this last season with pitcher Joe Kelly, who spent the majority of the summer in Pawtucket.  After a strong September (0.64 ERA in 14 IP) Kelly was added to the post season roster, and was arguably the Red Sox best pitcher in October (0.0 ERA in 3.2 IP)

With roster expansions just over a week away, here’s a look at who might be coming up to Fenway and what you can expect.
