plunk rates by distance
Following up on Friday's post regarding how far away Craig Biggio has been when he's collected his 136 road HBPs, today's topic is how his rate of getting hit changes with respect to distance from Houston.
Craig Biggio has been hit most often, 45 times, in parks between 750 and 1000 miles from Houston. That range includes the parks in Denver, Chicago, Cincinnati, and Miami. But, his highest rate of plunks per plate appearance has occurred within 250 miles of Houston. Only the Texas Rangers play that close to the home of the Astros, and Biggio has been hit 5 times in 69 plate appearance at Arlington. That comes to a rate of 0.07 plunks per plate appearance, or an HBP every 13.8 trips to the plate.
The rate Biggio gets hit appears to be greatest in cities closer to Houston and drops off further away. He's been hit once per 43.1 plate appearance between 1000 and 1,250 miles from Houston, once per 47.8 PAs between 1,250 and 1,500 miles away, once per 83.7 PAs 1,500 to 1,750 miles away, and he has never been hit at the only park he's played in over 1,750 miles away (Safeco Field in Seattle).
Their are 9 ballparks in which Biggio has played a game but never got hit by a pitch, and only 1 of them is less than 1000 miles from Houston - Mile High Stadium, where the Rockies played before building Coors Field. 2 are between 1,500 and 1,750 miles from Houston (AT&T Park and Fenway), and the other 5 are all between 1,000 and 1,250 miles from Houston (Metrodome, Tiger Stadium, Comerica Park, Jacobs Field, and RFK Stadium).
Below is the chart of Biggio's rates of plate appearances per plunk grouped by mileage from Houston. The anomaly of the 500-750 range having a lower rate of plunkings than the 750-1000 range is most likely due to either the Braves underachieving - being last in the NL in plunking Biggio, and about 700 miles from Houston - or the Rockies overachieving, leading all teams in plunking Biggio including hitting him 15 times at Coors Field, about 880 miles from Houston.
