What happened: Lucas Spence, an undrafted free agent, played his 16th major-league game for Houston. He hit his first three career home runs in the same game.
Why it matters: Houston is in a tight September race where depth production decides positioning. A contribution from an unheralded roster addition eases pressure on the regular lineup and preserves margin in the standings.
By the numbers: Spence: 16 career major-league games; 3 career home runs, all in one game; third player in MLB history with first three homers in same game.
What to watch: Houston remains on the schedule for Sept. 25 as the race continues. Spence's usage down the stretch is the next indicator.
