"They're going to go from piranhas to sardines," Guillen joked about the Twins' new image after they settle in at Target Field. "A prediction is a prediction."
The move from the enclosed Metrodome, where the spongy turf afforded the Twins a major home-field advantage offensively, to the new open-air stadium, is being eagerly anticipated by their opponents as an equalizer -- at least early on.
But the Twins say the field will favor neither hitters nor pitchers, and Guillen is not exactly writing them off.
"The thing about them, they find a way to stay where they are [atop the AL Central]," he said. "How they do it, I don't know. They find a player from the Mexican League and all of a sudden they come play for the Twins and they're unbelievable. They find a way to make the players play well . . . and they're going to compete."
But Guillen warned the Twins and their fans to be ready for an entirely new game involving the elements.
"It's a different game now -- rain delays, doubleheaders, cold, rain," Guillen said. "Good luck, [Twins manager Ron Gardenhire]. Now he has to deal with what we deal with in the Midwest They have to deal with what we do every day and that's an advantage to the teams playing against them."
