Big picture, the Sox should not allow Eloy to play OF again. Multiple injuries and IL stints over 167 games, among the all time worst defensively when he is healthy enough to play.
Sure Eloy can injure himself running the bases or celebrating, but removing him from the OF will vastly increase his availability doing what he does best, batting for the Chicago White Sox. Mercedes is likely the odd person out, unless he can make adjustments and produce at a higher rate than he has in May.
