So it's not quite the same splits, but I went to Fangraphs and created a splits leaderboard with the following conditions:
Dates: 3-1-2016 to present Inning: 8, 9, or Extras Leverage Index: High, so LI of 2 or greater. Chart for reference of Leverage Indexes Minimum of 50 plate appearances
This left a total of 360 qualifying players. Trout ended up ranking 43rd in wRC+ with a value of 144 (44 percent better than average). The top player was Justin Smoak with a wRC+ of 215 followed by Kyle Tucker at 200.
Some interesting names and their rankings:
Name wRC+ Rank
Bryce Harper 183 6
Aaron Judge 166 11
Juan Soto 163 13
Shohei Ohtani 137 55
Mookie Betts 130 72
Kyle Schwarber 17 351
