The 2020 Replacement-Level Killers: First Base
In a race for a playoff spot, every edge matters. And yet all too often, for reasons that extend beyond a player’s statistics, managers and general managers fail to make the moves that could improve their teams, allowing subpar production to fester at the risk of smothering a club’s postseason hopes. In Baseball Prospectus’ 2007 book It Ain’t Over ‘Til It’s Over, I compiled a historical All-Star squad of ignominy, identifying players at each position whose performances had dragged their teams down in tight races: the Replacement-Level Killers. I’ve revisited the concept numerous times at multiple outlets, and have presented it at FanGraphs in an expanded format since 2018.
Things are different this year, as you may have noticed. With six days to go before the August 31 deadline, just a month’s worth of performance to analyze — if, that is, a team has avoided a COVID-19 outbreak that has blown a hole in its schedule — and 23 teams within two games of spot in the expanded playoff field through Monday, putting together this year’s set of Replacement-Level Killers is a challenge like no other. The sample sizes are tiny, especially when players are sharing a position; month-long slumps are hardly unique. Even without being a complete devotee to exactitude, normally I’m able to curate a tidy list at each position by focusing on the subset of contenders (teams with .500 records or at least a 10% chance of reaching the playoffs) who have gotten less than 1.0 WAR at that spot through roughly two-thirds of the season. Scale that down to 30 games, and the threshold becomes 0.3 WAR or less, in which case a single good day by a player at the position in question might boost him from Killer to mid-pack producer.
Thus, I’m doing things a bit differently this time around. While still focusing upon teams that meet the loose definition of contenders (apologies in advance to fans of the Royals, Angels, Tigers, Red Sox, Rangers, Mariners, and Pirates), I’ll incorporate our Depth Charts rest-of-season WARs into the equation, considering any team that comes out with a total of 0.4 WAR or less to be in the replacement-level realm (that’s 1.1 WAR over the course of 162 games, decidedly subpar), though I may give a few teams in each batch a lightning round-type treatment, as I see their problems as less pressing given other contexts (returns from injury, contradictory defensive metrics, bigger holes elsewhere on the roster etc.) and I’ve pledged to keep these from becoming 3,000-word tomes.
