Justin Verlander’s Innings Could Fill a Boat
As Justin Verlander takes the mound tonight, he’ll do so with 240.1 innings pitched this season between regular season and playoffs. In the last three seasons, Verlander’s 2019 campaign is just the second to go at least 240 innings; his 242.2 inning in 2017 is the other. Since 2011, there have been 26 seasons during which pitchers have thrown at least 240 innings. Verlander accounts for five of them. If he makes a decent start tonight and Houston advances to the World Series, he’ll likely be the first pitcher to go over 250 innings in a season since 2014, when James Shields, Madison Bumgarner, and David Price all eclipsed that mark. Verlander’s quality deservedly receives the bulk of the attention when analyzing the ace, but the quantity deserves accolades as well.
If we look a single player’s career and then compare his totals to his peers only during those seasons when he was active, it is bound to be misleading, as it cuts off the careers of others at the beginning and end where fuller comparisons are better made. For example, Justin Verlander’s 72 WAR is first among all pitchers since 2006 when he pitched his first full season. That Verlander was the best pitcher in baseball over that time is a defensible argument, but it should be noted that Clayton Kershaw is just seven wins behind Verlander and five years younger. If we looked at the leaders from 2006-2026, Verlander might not be first. Similarly, if we go back to 1996, we see Randy Johnson and Pedro Martinez jump ahead of Verlander. If we go back to 1986, Roger Clemens and Greg Maddux are more than 40 wins ahead of him, with Mike Mussina, Curt Schilling, John Smoltz, and Kevin Brown also in possession of a higher WAR. This isn’t to take away anything from Verlander — the other pitchers discussed are all great. But it is a reminder that selectively choosing seasons can skew the results. Read the rest of this entry »
