National League West Preview 2021 – Arizona Diamondbacks

D-Backs Playoff Hopes Demand Good Health

Our NL Arizona Diamondbacks preview 2021 notes that in 2020 this team came in last place. The ‘Backs ended the season with a 25-35 record, which, adjusted to a 162-game schedule, is 68-94. Last year, Arizona saw its pitching staff fall apart, and as the season slipped away, they sold off much of their talent. In order to have a run at the postseason this year, the Diamondbacks need everyone to be healthy. It does not look like they will start the 2021 season that way, as five of their key players start the season listed as day-to-day. Hopefully, this trend towards ill-health won’t become contagious in 2021.
