Houston Astros right-hander Justin Verlander has a no-hitter through seven innings against the host Toronto Blue Jays.
After walking Cavan Biggio with one out in the first inning, Verlander retired 20 in a row through seven innings on 93 pitches.
Verlander has thrown two no-hitters in his 15-year career, most recently against the Blue Jays on May 7, 2011, when he was still with the Detroit Tigers.
The eight-time All Star and 2011 AL Cy Young Award winner threw his first no-hitter against the Milwaukee Brewers on June 12, 2007.
Verlander entered Sunday leading the AL in ERA (2.69), innings (184) and second in wins (16) and strikeouts (243).
