No Team Is Shifting Like the Padres
The recent flurry of matchups between the Dodgers and Padres have been enthralling. That’s what transpires when two teams of similar caliber go head-to-head – both clubs feature impressive lineups, employ the league’s best starters, and have quality bullpens and bench options to maintain the tension in later innings. They also both possess good front offices. The Dodgers have long been at the sabermetric forefront, while the Padres have strengthened their analytics department over the last few years. They share multiple characteristics, and not surprisingly, both teams excel.
However, the intrastate rivals do disagree on one major aspect of the modern game: infield shifts. Since last year, the Dodgers have applied the shift in 58.0% of opportunities, a league-leading rate over that span. In contrast, the Padres have done so just 21.5% of time. Only the Cardinals and Braves, two teams that are notably shift-averse, recorded lower rates.
What’s interesting, though, is that this isn’t because the Padres dislike the shift. Let’s dig a bit deeper. The Dodgers are what you would call equal-opportunity shifters – that is, they don’t discriminate between left- and right-handed hitters. Of their 6,729 shifts during the aforementioned time span, 3,210 (47.7%) of them were against the former. (Here I should clarify that I’m only factoring in Baseball Savant’s shifts, not strategic alignments, to simplify the analysis.)
Ok, now for San Diego. Their total of 2,608 shifts is much lower, but, and I kid you not, 2,524 (96.8%) of them were against left-handed hitters! And no, the Padres didn’t stumble into this. The gap between them and second place, the Rockies, is about 18 percentage points. There’s clear intent here, which looks even more impressive on a graph:
