Springer's nine leadoff homers are a single-season franchise record, surpassing the previous mark of eight set by himself in 2016 and Craig Biggio in 2001. His 18 career leadoff homers are second in club history behind Biggio's 53.
MLB's single-season record for leadoff homers is 13 set by Alfonso Soriano in 2003.
With the 342-foot shot in the first inning, Springer also set a new franchise record for most home runs from the leadoff spot in a season with 24. Springer is the first Astro with 24 homers before the All-Star break since Lance Berkman had 24 in the first half of 2006.
