Through five innings, Carlos Martinez's only blemish is a home run.
Martinez has cruised since allowing a second-inning solo homer to Toronto catcher Russell Martin. The St. Louis starter has also struck out seven while walking none on 70 pitches.
However, the home team has failed to score and the Blue Jays still lead 1-0.
The Cardinals got a runner to third base in the bottom of the second but could not convert the chance into a run. Blue Jays starter Mat Latos has held St. Louis at bay despite only striking out two batters.
