Tuesday's clash against the Mariners will be the Astros fifth straight game without an off-day, and will be the first time that the squad has had to go beyond its five man opening day roster to find another starting pitcher. Let us first note how remarkable this is. As of Friday, 304 men had started a game in the major leagues this year. That's an average of over 10 starters per team Even if you take the Tampa Bay Rays and all of their "openers" out of the equation (they've had 15 different starting pitchers), each team has averaged 9.
