What happened: Nolan Arenado was pulled from Monday's Diamondbacks game with left trunk discomfort, the team announced. Arenado is scheduled for an MRI, per reporter Jody Jackson.

Why it matters: The exit comes a day after the same Arenado who hit two home runs in Sunday's game. Any extended absence would remove one of Arizona's most productive bats from the lineup.

What to watch: Arenado's MRI results will determine his availability for Arizona's next game.
