Yesterday, commenter aburioe asked:
How many times has Biggio faced the pitcher who last plunked Biggio (same game plate appearances excluded, of course)? And of those, how many have ended up in a repeat plunking?
The second part is the easy one. On July 28, 2001 Jimmy Anderson of the Pirates delivered Biggio's 192nd plunk in Pittsburgh. On August 18, 2001, when the Pirates visited Houston, Anderson hit Biggio again for plunk number 193. And just last year, Jason Jennings of the Rockies hit Biggio twice on June 22nd, for plunks number 265 and 266. The following week, Jennings delivered plunk 267 to tie Don Baylor. Those two are the only instances of consecutive plunks by the same pitcher on different days.
Finding out how many times Biggio has actually faced the last pitcher who hit him is a bit beyond the data I have, and perhaps my attention span. By my count, there have been 363 games in which Biggio played against the team that last hit him. That doesn't take into account how many pitchers might have hit Biggio, changed teams and faced him again on his new team. Browsing the early part of Biggio's career, Mike LaCoss faced Biggio on 8/5/89 after hitting him on 7/30/89, Calvin Schiraldi faced him on 8/11/90 after hitting him on 7/28/90, John Smiley faced him twice in May of '91 after hitting him in September of '90, and Barry Jones hit him on 8/30/1991 and faced him 3 time in May of '92 (after moving to the Phillies), before Biggio got hit again in June. So from that small sample, the answer seems to be "a lot". I'll revisit this at some point if I can find a way to get to a more complete answer.
