A fellow baseball blogger, Sky Kalkman wrote something interesting this morning. In a post exploring the relationship between control and command for pitchers, Sky opined:
My non-expert hunch is that one of the main reasons pitchers don’t throw more pitches in the strike zone is that their stuff isn’t good enough. They aim for the edge of the zone because the cost of missing outside (a ball) isn’t as bad as the cost of missing over the heart of the plate (a line drive or home run.) A pitcher with impeccable aim but mediocre stuff won’t rate highly in control.
My first impulse was to disagree with Sky, considering Greg Maddux threw in the 80s for much of his career and was an expert at slowly widening the strike zone. With a look at the numbers, though, Sky may have a point.
It’s relatively unheard of in baseball history for starting pitchers with at least 162 innings in a season to strike out fewer than 150 batters and post SO/BB ratios of 5.00 or better. Brad Radke and David Wells did it three times apiece. Bret Saberhagen did it in 1994 when he posted an 11.00 SO/BB ratio, the best ever for a starting pitcher. Otherwise, the feat I speak of has been done just four other times since 1901, including just once prior to 1985.

These men are the minority. Of the 57 other times since 1901 that a pitcher has had a SO/BB ratio of 5.0 or better all have recorded at least 150 strikeouts. I suppose this makes sense in that a pitcher can walk a lot of batters and maintain a respectable SO/BB ratio if he has more strikeouts and that low walk totals are uncommon for pitchers, strikeouts or no. A pitcher with 150 strikeouts could walk no more than 30 batters to have a 5.0 SO/BB ratio. In 2011, just two pitchers with at least 162 innings had fewer than 30 walks.
It goes without saying that many pitchers have thrown at least 162 innings in a season with SO/BB ratios of 5.0 or lower. In 2011 alone, 44 pitchers did this, with hurlers like Jake Westbrook, John Lannan, and Brad Penny having scarcely more strikeouts than walks. Maybe Sky has a point. Maybe guys like Westbrook, Lannan, and Penny knew their stuff wasn’t that great and that they’d be best-suited sticking to the fringes of the strike zone. It makes me wonder what Radke, Wells, and Saberhagen were doing differently.
