Mason Miller’s last two pitches to Seiya Suzuki in the seventh inning were clocked at 102.1 and 102.7 mph. Suzuki swung and missed at the last one for strike three. It turns out Miller was only warming up. The 6-foot-5 right-hander played a starring role in a dominant performance by San Diego’s bullpen in a 3-0 victory over the Chicago Cubs, sending their NL Wild Card Series to a decisive third game. Miller came in after Adrian Morejon pitched 2 1/3 perfect innings in relief of Dylan Cease. After fanning Suzuki, he reached 104.5 mph on a called third strike to Carson Kelly that was the fastest pitch in the postseason since Statcast started tracking in 2008.
