Verlander has struck out 13 and thrown 106 pitches Sunday at Toronto. The only runner he's allowed was Cavan Biggio on a one-out walk in the first inning.
Verlander has thrown two no-hitters in the majors, both while with the Detroit Tigers. He pitched a no-hitter at Toronto in 2011 and also accomplished the feat against Milwaukee in 2007.
The Astros-Blue Jays game is scoreless — Houston would have to score for Verlander to be credited with a no-hitter.
The 36-year-old Verlander leads the majors in strikeouts and innings. He tops the AL in ERA and is tied for second in the majors with 16 wins.
