James’ Pythagorean standings break down the metrics of a team (the biggest numbers being runs scored and runs allowed) to produce a sum of expected victories. In a small sample, the formula can be argued. But looking at manager’s careers, it seems a reliable tool that takes the bias out of the equation.
Twice hired in mid-season and once fired in mid-season, Valentine has compiled a plus-23 Pythagorean rating in his 12 full seasons managing the Rangers and Mets — an average of plus-1.9.
How good is that? In Tony La Russa’s 31 full seasons with the White Sox, A’s and Cardinals, he was a plus-23 — an average of plus-0.7. In Bobby Cox’s 27 full seasons with the Blue Jays and Braves, he was a plus-16 — an average of plus-0.6.
