"They'll have roles within the team. They won't be on the diamond every single game, but they certainly add real experience to the bench and know that international environment."

"The selection process has been very difficult and there are obviously some very good players who didn't make the final selection," Kohlhase said. "But we're very happy with the 17 we've selected.
"We believe we've picked a team to win it. We've got a lot of speed and power, and a lot of youth and experience. If we can mould that all together with the team operating as one, we'll be very hard to beat."
