Mains: The tenure track for baseball managers

From SABR member Rob Mains at Baseball Prospectus on April 19, 2018:

Heading into the season, [Mike] Scioscia had managed the past 2,916 Angels games. Only five other teams are led by managers who’d been on the job for at least 1,000 games: Bruce Bochy of the Giants with 1,782, Ned Yost of the Royals with 1,261, Buck Showalter of the Orioles with 1,191, Clint Hurdle of the Pirates with 1,134, and Bob Melvin of the A’s with 1,071.

On the other hand, the Red Sox’s Alex Cora, the Tigers’ Ron Gardenhire, the Mets’ Mickey Callaway, the Yankees’ Aaron Boone, the Phillies’ Gabe Kapler, and the Nationals’ Dave Martinez came into the year with zero games with their respective teams under their belt.

The average manager’s tenure heading into the year was 585 games. But that probably overstates things because of Scioscia. If we throw out the high and low figures, that drops to 523 games. And if we look at the median, it’s 474 games. That’s fewer than three years. That’s not a lot of tenure.
