3 things Oliver Marmol has done well this year and 1 thing he butchered

Oliver Marmol has conducted himself professionally all year.

A manager should make as many correct decisions as possible in a game. This gives his team the greatest chance to succeed. But if the decision doesn't pan out well, the manager should at least be able to defend his thought process regarding the particular move. Oliver Marmol has been excellent at this part of the job.

Manager decisions won't always pan out in the team's favor. Baseball is a game where a player can get a hit just 30% of the time and be recognized as one of the best hitters in the sport. The same logic can be applied to managers. If a manager's decision doesn't turn out well, he should at least be able to provide solid reasoning for his decision.

The most recent example of Oliver Marmol making a bold decision with solid logic came on September 4th against the Milwaukee Brewers. In the 10th inning, the Cardinals were up 3-2. Ryan Fernandez replaced Andrew Kittredge, and he struck out the first two batters. Jackson Chourio, the Brewers' talented rookie, was due up.

Marmol opted to intentionally walk Chourio, thus placing batters on first and second base with two outs and Rhys Hoskins due up. Fernandez has thrived at striking out batters this year, and Hoskins has a 27% strikeout rate this year. It was a risky choice, but it paid dividends, as Fernandez would indeed strike out Hoskins and record a save.

This is just one example of Marmol making a difficult decision that could pan out poorly, but he at least defended it well and made an informed decision. This has been something Marmol has done frequently all year.
