"So, it's really a good time for us and an opportunity for them. We just have to kind of try to evaluate. Even your main guys, you can't judge everything that's happening right here. Some guys are slower starters and not quite built up to where they want to be yet."
That's not to say that a few Marlins prospects haven't had their share of superlatives this spring. First baseman Tyler Moore entered Thursday's game tied for the Grapefruit League lead in home runs with three. Outfielders Matt den Dekker and Destin Hood both came in hitting .278.
But the Grapefruit League win-loss record becomes secondary to preparation for the bigger picture. And although Spring Training runs a bit longer this year, there never seems to be enough time to get a good look at all 63 players who opened Marlins camp.
"Unfortunately, you don't get that many opportunities, so you are looking and judging and trying to make the best decisions on guys," Mattingly said.
Disregarding the number of wins his team has accumulated so far this spring, Mattingly is nevertheless pleased with what he's seen.
"I feel like our effort has been good and our work [this spring] is good, and the guys have been focused."
