Marlins vs Astros Prediction

It would be nice to know who the Astros are throwing on the mound, but I’m rolling with the Marlins anyway. The Marlins have been the hottest team in baseball over the last couple of months, and they’re enjoying a strong week at home. Quantrill is also coming off a great July where he allowed 21 hits and eight earned runs in his last 24.2 innings. The Marlins have won seven of Quantrill’s last eight starts. The Marlins have lost back-to-back games just twice since July 12. Give me the home team on Tuesday.
