Drew Storen has not had a very good couple of weeks. He has a 4.05 ERA and two blown saves. There are a few stats out there that help us guage the component of luck when it comes to pitching especially when dealing with a small sample size like two weeks.
Batting Average Ball In Play (BABIP): Measures the balls that fall in for hits. The average BABIP is in a range from .290 – 3.10. For the last two weeks the Nats relievers have a BABIP of .302, right in that range. You can see below, over the last two weeks, Drew Storen’s BABIP is really high which would be the first indication that of fluke or unlucky
Next we need to measure the batted ball. If the other team is hitting the ball hard on-line drives then obviously BABIP will be higher than weakly hit grounders. With Drew, he is getting a low % of line drives.
The third stat line to look at is % of strike outs. With this stat, you can see why Clippard has been so good considering his high fly ball and line drive numbers. He is striking out over one batter an inning. Storen, is getting K’s but at half his career average of 22%. One thing of concern is his walk rate is about twice his career average.
I think Storen’s last few weeks is more about bad luck such a grounder making it through the infield and issuing slightly more walks than normal.
