What happened: No. 298 came during the final month of Alonso's eighth MLB season. It followed an opposite-field go-ahead homer in August.
Why it matters: The 300-homer club had 170 members as of July 2026. Reaching the mark would add another milestone to the five-time All-Star's career.
By the numbers: Career home runs: 298. Home runs in 2026: 34. Distance to 300: 2.
What to watch: Alonso's remaining September plate appearances will determine whether he reaches 300 before the postseason.
