I disagree - He brought in the right pitchers at the proper time they just did not execute. I see it more as an execution issue than a game management issue. Not to say that Schneider is great at managing the pen -- he has done some strange moves in the past -- but I don't think tonight was one of those nights.
Gausman was at 95 pitches, the bases were loaded, lefties are due, so he brings in the only lefty in a relatively low leverage situation with the score at 8-1. Makes good sense at the time especially with a relatively fresh pen to get the last 10 outs.
Bass was the right guy to bring in the 8th inning - arguably the Jays second best reliever... he stank it up. What is Schneider to do? So he brings in Romano in the 8th which again makes sense, but he got dinged with a cheap bloop hit that scored 3.
