The 2019 Replacement-Level Killers: Second Base
While defensive concerns generally outweigh offensive ones when it comes to second basemen, it nonetheless rates as a surprise that the position’s denizens are producing just a 90 wRC+, their lowest in the period covered by our splits (since 2002) and the lowest of any position this year save for catcher. After all, in 2016, the group reached its high-water mark for the period with a 106 wRC+. Even as teams have squeezed offense-minded players like Mike Moustakas and Max Muncy into the keystone, the collapses of several formerly solid second-sackers — Robinson Cano, Starlin Castro, Brian Dozier, Josh Harrison, Kolten Wong, and many others mentioned below — have eroded the overall production here, as have the shifts of Daniel Murphy and Neil Walker to first base and the possibly career-ending knee woes of Dustin Pedroia. Perhaps that’s the point; the core of players that shined in 2016 has aged, and as Baseball Prospectus’ Aaron Gleeman suggested last month, it may just be a changing-of-the-guard moment.
Among contenders (which, for this series, I’ve defined as teams who are above .500 or have playoff odds of at least 10.0%, a definition that currently covers 17 teams), five have gotten less than 1.0 WAR at the position thus far. I’m including a sixth here, since we’ve had a bit of a reshuffle since I began writing the series: the Giants have won nine out of 10 and 16 out of 19 to climb to 51-50, while the Rangers have lost eight straight to fall to 50-50, that after I’d already written their entry, and I’m not making two stops. As at the other positions I’ve examined thus far, a closer look suggests that some of these teams are likely to remain in-house while shuffling through potential solutions rather than make a deal before July 31, but given the finality of this year’s deadline, this is an exercise worth doing at this juncture nonetheless.
