What happened: Pete Alonso went opposite field for his 39th home run of the season. The homer came in his eighth major-league season.
Why it matters: The total puts him one shy of another 40-homer campaign after four such seasons. Opposite-field production shows power beyond pull-side slug.
By the numbers: 39 home runs this season; four prior 40-homer seasons in eight MLB seasons.
What to watch: He sits one shy of 40 with the regular season winding down.
