A successful baseball team needs depth. The 162-game season is a long and winding road filled with ups and downs, and an entire roster cannot remain completely healthy for the whole year. This creates opportunities for those who were not otherwise counted to be contributors to become potential role players. Having quality depth can be the difference between a club being sunk by injuries or staying afloat when their roster is at less than 100%.
For the 2021 Brewers, that depth has come from a rather unlikely source in Jace Peterson. There was no reason to expect any level of productivity from Peterson.
