"You can make your moves and make your defensive substitutions," he said. "I know when I was in the American League, the nine guys played and the bench guys, it was tough to get them enough work to be consistent. That was always the challenge in the American League."
DeFrancesco managed for 16 years in Oakland's system before coming to the Astros' Triple-A affiliate in 2011. He took over in August at the Major league level after Brad Mills was dismissed.
But there is one part of the NL game that DeFrancesco didn't like to see, especially when his team was on offense.
"I don't like it when the pitcher comes up [to hit]," he said "That's something that I had to get used to for two years. Early in the game, when you have a chance to score runs and there's runners on second and third and one or two outs, the game kind of stops. If they get a hit, that's a plus, but most of the time they're going to make an out and stop everything."
