With the Texas Rangers firmly in the playoff hunt, it is time to start looking towards September when rosters expand to 40 players. There always seems to be one guy that is called up that performs well and sneaks onto the postseason roster or cements a spot on the opening day roster for next season.
Last year, it was Clay Rapada who came out of nowhere to make the postseason roster and pitch against the Yankees in the ALCS.
Could there be another Rapada this season? Almost assuredly, but who?
It's hard to tell, but there are clues.
First, they have to be on the 40-man roster to be eligible to play in September. If they're not, a spot must be made available for them. Obviously, players on that 40-man roster already are at an advantage over someone who is not.
Next, it's very unlikely Martin Perez is called up so temper your expectations. He's not ready for a shot in the majors and there's no spot for him right now on a postseason roster. There's also no spot for highly touted prospects Mike Olt or Tommy Mendonca.
Anyone who will be called up with a chance to make the postseason roster must fill a void.
That means a bullpen arm or a guy that can come off the bench. Only one player on this list is a potential starter in the postseason and no starting pitcher called up will make the postseason roster as there is already a logjam at the position.
With that said, here is a list of five September call-ups that could crack the postseason roster.
