Jean Segura and Salvador Perez: The Quest to Never Walk
Today we’re on a quest of sorts. It’s not a holy grail-type of quest, but then again, in a way we are looking for a grail: it’s just the grail of never walking. That’s not the actual intention of these hitters, because walks are a good thing if you’re a batter, and at some point you simply have to walk — no matter how hard you try not to — because a pitcher is going to come along and throw you nothing but junk. The lack of walks for these guys are just a product of their approach, and hitters with this kind of approach either quickly lose their job or are really good at other aspects of the game.
Take, for instance, the hitters we’re going to discuss today: Jean Segura and Salvador Perez. You might not have visited their player pages recently, but take a look at a few select categories in their stat lines from this past season:

| BB% | K% | wRC+ | BsR | Off | Def | WAR | |
| Jean Segura | 2.2% | 15.9% | 62 | 3.1 | -22.6 | 6.7 | 0.3 |
| Salvador Perez | 2.4% | 14.8% | 87 | -6.7 | -14.9 | 12 | 1.6 |
A few things jump out. Holy moly those walk rates. Below average (in one case, very below average) offensive numbers. And finally: solid defensive ratings. That last point is the main reason these two players garnered a combined 1137 plate appearances this past season despite their woeful offensive production: Segura is an above-average defensive shortstop (also providing speed on the base paths), and Perez is one of the best defensive catchers in baseball. Even though Segura’s playing time will be in question following his trade to the Diamondbacks, this goes to show you the kind of bat that can stick at these thin positions for most or all of a season.
The walk rates are the thing on which we really want to focus today, however, because they’ve rarely been paralleled in the past century. If we look at individual season walk rates going back to the start of the live-ball era (1920), we find Segura and Perez at the extreme end of the leaderboard among qualified hitters: in 2015, Segura tied for the 23rd-lowest walk rate since 1920 at just 2.2%, and Perez (with a walk rate of 2.4%) tied for the 40th-lowest mark. We could go into the hundredth decimal place to break some of those ties, but we won’t. We could even go further and factor in intentional walks, noting that Segura had two and Perez had four, but that seems unnecessary. We get the point: in relation to average full-time major league hitters, these two basically never walk.
