What happened: The exit came during Monday's 9-0 win. Three weeks earlier, Perdomo fueled a seven-run rally.
Why it matters: Any absence would create a lineup decision at shortstop during the stretch run. The regular season has fewer than two months remaining.
By the numbers: Two lower-body issues have interrupted Perdomo's 2026: a left ankle sprain in April and left knee soreness in August.
What to watch: His availability for the next game and any subsequent injury designation bear watching.
