Orioles are rather unique when it comes to double plays

An angle about this weekend series in Atlanta that seems to have missed being discussed is that the Braves and the Orioles represent extremes in one special way: Ground into Double Plays.  The Orioles have had the most GiDPs for most of the season and currently sit at 73, eight ahead of the next hopeful, the Minnesota Twins.  The Braves, on the other hand, seem to be quite adept at avoiding double plays.  By pure count, the Braves are tied with the Red Sox with 40 GiDP for third in MLB.  However, if you calculate the percentage of base runners at first base with less than two outs, the Braves have the leanest GiDP rate in the league.  The following graph illustrates this:


The league average rate is 11.4% of runner on first base with less than two out being involved in a double play.  The Orioles' value for this metric is 15.7%, which is 38% greater than the league average and 2.42 standard deviations away.  The Braves are 23% less likely to ground out in a double play than the league average with a rate of 8.7%.  This story has remained relatively consistent through the first two games of the three game series with the Orioles leading the Braves 5 to 2 in GiDPs.

What is interesting is trying to figure out why the Orioles are much more proficient in inducing these than Atlanta is.  First off, both teams hit about the same amount of ground balls with the Orioles having the 13th highest rate in baseball and the Braves with the 16th highest rate.  If you put any stock in Speed Scores, the Orioles have the least team speed in baseball and the Braves are average.  However, a comparison of speed score with GiDP does not yield much.  For instance, the second slowest team in baseball according to this metric, the Red Sox, have the second lowest GiDP rate.  Fangraphs Base Running metric also does not yield much as the Orioles rate as average and the Braves rate are a fringe first division team on the base paths.

J.J. Hardy has the most GiDPs on the team with 11.  He actually hits fewer ground balls than a league average hitter.  He has always had a variety of players bat in front of him who are not exactly slow (Endy Chavez - 19 times; Nolan Reimold - 14; Robert Andino - 13; Xavier Avery - 11).  Hardy appears to be having bad luck.  He is on pace to shatter his previous mark of 18 GiDP in a season.  I expect him to do better in the future.

The next two players on the Oriole leader list I am less sure about.  Adam Jones is second with 9 GiDPs.  Half of his hit balls are grounders and he has had Hardy and Nick Markakis in front of him (not exactly burners on the base paths).  Third is Andino with 8 GiDPs, which may result from half of his hits being ground balls and having players like Luis Exposito and Chris Davis bat in front of him. 

The Orioles propensity of GiDP may simply be due to lineup construction and the specific attributes of the team's star players.  The Orioles have a number of good players who happen to be unlucky or simply have a greater chance for ground balls.  When this is combined with other good players on the team not having good speed, it can result in a heavy GiDP situation.  The Braves on the other hand have a burner in Michael Bourn and players like Dan Uggla, Freddie Freeman, and Brian McCann who simply do not hit ground balls (33%, 35.2%, and 38%).

Hardy nearly always tries to pull pitches on the outer edge of the plate. That tends to result in grounders to the left side, usually shortstop. With a runner on first, that's a DP.

It's not necessarily the player in front of the GIDP hitter that is crucial. Few runners from first can outrun a ground ball/throw to second; it's making it to first that puts the double in double play. Hitting the ball hard contributes to GIDP for the batter. And having a high strikeout rate among Oriole hitters probably makes Showalter reluctant to send the runner (he never was a big stolen base manager). I'm sure there are stats out there, measuring how often a runner is sent...

Great article

Yes, the speed of the runner going to first is important when you get to plus speed. However, I would argue that the closer a runner is to second, the more difficult a throw becomes for a fielder. To me, that is a major issue. I think too much weight is given to batter speed merely because that is the end of the play.

Thanks Matt.
