Severe LHP bias. And he was brought in to face a lefty, IIRC. Escobar career splits (these include Escobar's horrible 22-24 age seasons): RHP: .640 OPS LHP: .766 OPS Vargas career splits: RHP: .733 OPS LHP: .771 OPS I would have let Vargas hit in that situation but once you dig into the numbers, the decision becomes defensible. It's certainly not idiotic by any means. Against LHP pitching in their careers, Escobar and Vargas have nearly identical splits in batting average, on-base percentage, and slugging; within a few points of each other on all three slashes. Difference of opinion should not be conflated with right/wrong, especially when the numbers don't back up your argument and are deep into a grey area.
