The 2018 Replacement-Level Killers: Shortstop and Third Base

We live in amazing times when it comes to the collection of talent that is occupying the left side of the infield — or is supposed to be, if not for injuries (we miss you, Corey Seager, and please come back soon, Carlos Correa and Josh Donaldson). Remarkably, at a position where defense reigns supreme, shortstops as a group are hitting for a collective 99 wRC+ at this point, up from the range of 87 to 92 that it’s occupied since 2002. Third basemen are at a high as well as far as offense with a 108 mark. And in case you haven’t seen the highlight reels, there is no shortage of guys from these two positions who can Pick It.
As it happens, nearly every contender this year — which for this series I’ve defined as teams with playoff odds at least 15.0%, a definition that currently covers 16 teams — is outfitted well enough at the two positions, having balanced offensive and defensive concerns such that there’s a dearth of Replacement-Level Killer candidates. Only three teams from among the eight who have received less than 1.0 WAR from their shortstops are contenders, and likewise, just three others from among the 10 are in the same situation at third base. One team has needs in both areas, namely the Pirates, whose 11-game winning streak has pushed their odds above 15% and thus forced me to include them in this exercise, even though you, I, and Bob Nutting all know they’re still very long shots.
