​In the postseason, any base runner that reaches is a rally. That seems like a very basic statement, but it's true and could really hurt the Boston Red Sox come October, as their ​bullpen is susceptible to giving up free passes.

​​It's not like the top guys in the back end are exempt, as they are actually part of this problem. Heath Hembree, Joe Kelly, Matt Barnes and Craig Kimbrel rank towards the bottom half of 150 qualified relievers in walks per nine, which is really concerning when you think about how they are going to be able to close out important games in October.

On top of this leaky bullpen, the Red Sox have to be concerned about their ace Chris Sale, whose ​fastball velocity has gone way down since coming off the disabled list with shoulder inflammation.


If Sale can't pitch like one of the best pitchers in the AL like he's done over the course of their career and their bullpen can't do a better job containing base runners by walking less batters, this could be a short World Series run for a team that already has 107 wins.
