improbable

Yesterday, reader dm asked who the most unlikely Biggio plunker was as measured by HBP per batter faced. Lance Davis pitched 20 games for the Reds in 2001 and hit just 1 of the 461 batters he faced. That one batter, of course, was Craig Biggio. Among pitchers with slightly longer careers than 20 games, Bob Ojeda leads this category. He hit 24 of the 7977 batters he faced, but Kirk Rueter has managed to hit Biggio twice even though he's only hit 25 total batters of the 8077 he's faced to date. Two other pitchers have hit Biggio twice with under 25 hit batters in total, Mark Clark and Brian Anderson.
For another perspective on who is the most unlikely pitcher who has hit Craig Biggio with a pitch, take a look back at Mike Carminati's post here. In the table where he lists the pitchers with the fewest HBPs compared with expectations, Kirk Rueter is the only one in the list who has plunked Biggio.
