Adames left Sunday's Giants win over Atlanta in the eighth inning after his lower back locked up. Manager Tony Vitello confirmed he has been dealing with back spasms for about a week and is also battling the flu. MRI results are expected Monday in Arizona, and Vitello acknowledged an IL trip is possible depending on the imaging. The 30-year-old is one of the Giants' most important offensive contributors and his availability for the upcoming Diamondbacks series is genuinely uncertain.
