Sorry, but did you think Tommy Nance was a better option after the leadoff walk in the 9th? I don't know about you, but I'd probably take my chances that Hoffman figures it out over praying that Tommy Nance somehow dominates the Dodgers lineup with men on in a high stakes situation. Just because Hoffman totally s*** the bed with his command doesn't mean he might have been one mound visit away from being by far the best reliever we had available. Once Ohtani's spot became a guarantee to come up, you had to ride Hoffman out until you could use the lefty, it is what it is.
Here are the possible alternatives:
1. Hoffman walks leadoff hitter. Bring in unknown Tommy Nance with a runner on over hoping your ~second best reliever with strikeout stuff figured it out. Total hindsight move. Much higher chances that Hoffman pulls it together and dominates from here than Tommy Nance not blowing it up.
2. Hoffman walks first two. Bring in Nance, guaranteeing Ohtani comes to bat with a very favourable matchup and at least one runner in scoring position. Reminder that Dodgers would gift us an out, but would take the possibility of a double play away in doing so. Lose-lose situation either way whether you keep Hoffman or bring in Nance. At least in the latter situation, you could bring in Fluharty to face the lefty when necessary.
3. With the likely possibility of the Dodgers at least tying the game, you're now down to one reliever in the bullpen entering the 10th, your odds for winning the game crater at this point.
