What are his high leverage numbers like for his career? Is it just a one year blip or is this something we'll have to deal with for 6 more years? My understanding is that the general belief is still that there is not a clutch hitting skill and WPA changes from year to year for an individual player.
Fake Edit: I did the work, somewhat
Career: .740 (.750 this year)
Late & Close: .730 (.683)
2 outs, RISP: .782 (.683)
High Leverage: .802 (.680)
Innings 7-9: .739 (.636)
Vs. Relievers: .745 (.654)
So it looks like for his career he hits roughly the same in "big spots" as he does in other situations, just not this season. Though when digging, I found that he was actually significantly above average in a lot of these categories his first 5 seasons and has had numbers like this years for the last 3 seasons (2021, 2022, 2023). No idea why there is such a sudden shift, but there's at least some evidence using 3 years of data that Swanson is doing something different in clutch situations.
Even if clutch hitting isnt a thing, while he slumps like he has for the last 6 weeks he should be hitting 7th in the order, not directly between Bellinger and Seiya. He's come up in a lot of big spots and has been pretty much worthless to the team in those spots lately.
