  1. "Prior to the 2020 MLB season, Sports Info Solutions (SIS) announced major upgrades to its flagship defensive metric, Defensive Runs Saved (DRS). These upgrades centered around the incorporation of infielder starting positions in the calculations and the improvements that were consequently able to be made."

    ...

    "Whatever credit the fielder may receive or lose on a play is based on where they were standing when the ball was hit, rather than simply assuming they were standing in a traditional starting location."

    Looking at Team Shift Runs Saved (rTS) it somehow has the Angels at #1. It looks like the same data as the fieldingbible uses, just shift and non-shift added together.

    "rTS measures whether a shift is doing what it is supposed to do – get outs on ground balls and short line drives that wouldn’t have been achieved with the traditional infield alignment. The calculation is done at the team level rather than the individual level."

    All of that doesn't mean that the Angels are a good defensive team. They're bad. Now I wonder if every time I witnessed the shift failing it just added to some confirmation bias. Maybe Iglesias (-23 DRS) was really that bad independent of the shift.
