Nolan Arenado was placed on the 10-day Injured List on Tuesday with left AC joint inflammation and a left shoulder bone bruise, effectively ending his season. In speaking with the media after the announcement, he said he believed the injury occurred during the series in Oakland on July 28-29. The shoulder had been nagging him all season, most notably at the plate since it was his non-throwing arm. His offensive triple slash was .253/.303/.434 in 182 at-bats — his lowest since 2013 (the batting average is his career lowest).
However, since the injury was to his non-throwing arm, Arenado’s defense didn’t suffer much.
