A recent example of a "too left-handed" team was the 2022 Dbacks.
They promoted LHH Corbin Carroll full time next season, but traded LHH Daulton Varsho for RHH Gabriel Moreno.
In 2022, they slashed .225/.281/.320 in 617 L/L match-ups.
In 2023, .215/.285/320 in 452 such plate appearances.
2024, .235/.308/.359 in 446 PA so far.
