Some lazy morning's graphing
This is just some puttering around with Excel, the database and my plotter. This isn't supposed to be mistaken for serious analysis.
That said - this morning I was discussing Bob Howry over at Bleed Cubbie Blue, and we got to discussing the fact that when Bob Howry is pitching, hitters are batting .320 on ground balls. When other people pitch, the league average is something like .230. This is a large part of Howry's problem - he actually has the lowest walk rate in the bullpen right now. But is this really Howry's fault?
There really isn't much evidence that Howry is pitching drastically differently this year - his ground ball/fly ball/line drive splits are all right in line with his career numbers. So is his velocity - he's throwing more sliders than he has in years past, for what it's worth.
So - and my play-by-play data for the season only covers through about the first week of August - I did a plot of ground balls hit off Howry. Blue dots are outs, red dots are hits:
Tell me what you see here.
