The 2019 Replacement-Level Killers: Shortstop and Third Base
As I noted yesterday, within the context of the 2002-19 period covered by our splits, second basemen have reached their offensive nadir, with a combined 90 wRC+ this year. At the same time, shortstops are building upon last year’s periodic zenith (97 wRC+) with an even 100 mark — in other words, one of the most demanding defensive positions is collectively producing league-average hitters. At least in part, that’s due to the kids. Last year, nobody older than 31 made even 150 plate appearances as a shortstop, and just three players over 30 played at least 100 games at the position, the lowest total since MLB expanded to 30 teams in 1998. This year, the Rangers’ Elvis Andrus, the Giants’ Brandon Crawford, and the Marlins’ Miguel Rojas are the only players on pace to do so.
Increasingly, shortstop is a young man’s position, and the crop of talent is remarkable: Alex Bregman, Carlos Correa, Paul DeJong, Francisco Lindor, Jorge Polanco Corey Seager, and Fernando Tatis Jr. are all in their age-25 seasons or younger, and of the 14 shortstops who have totaled at least 1.7 WAR thus far (including Gleyber Torres, who thanks to Didi Gregorius‘ injury has played more than twice as many games at shortstop than second thus far), 10 of them are 26 or younger.
Meanwhile, just seven teams, including three contenders, have gotten less than 1.0 WAR from their shortstops to date. For this series, my definition of contenders is teams who are above .500 or have playoff odds of at least 10.0%, a definition that currently covers 18 teams, with the surging Giants (52-50) joining the party since I kicked off this series. For as small as that group of shortstops is, I’m making it even smaller by omitting the Nationals, whose alternatives to Trea Turner have offset his 1.4 WAR with a combined -0.8, compiled mostly while he was sidelined with a broken right index finger. I’m skipping them and, as with last year, doubling up this entry with the third basemen, who are near their own offensive high for the period, with a 105 wC+ mark (they were at 107 in 2016, and 106 last year); just eight teams, including four contenders, are below 1.0. I’m omitting one of those as well, since the Brewers’ Mike Moustakas has not only delivered 1.1 of his 2.7 total WAR there while filling in for Travis Shaw, but has opened up second base for top prospect Keston Hiura, who’s off to a flying start (136 wRC+, 1.5 WAR in 39 games).
