"They were really patient, and that's probably one of the most patient Jamaican teams I've seen for a while. They put some quality ball into their shooters, and their shooters were on fire tonight."
From the first whistle, the Silver Ferns struggled to keep up with the fast pace of Jamaica - a very different game to that of Wednesday night when the Ferns thrashed Malawi.
Southby said the loss to Jamaica provided valuable learning experience and highlighted key areas the Ferns needed to approach in the lead up to Saturday's final.
"I think there's some things that we can definitely improve on," said Southby.
"We just lost that connection and confidence to put the ball in the hole and it was hard work getting it there.
"It's tough, the defenders jumped their hearts out and at times we got some really good ball, some well timed jumps, Temalisi [Fakahokotau] came in and added some real energy in there … but the ball we've got to get is on the other end.
"There's some stuff in the circle I think we need to look at, just making sure both players are working for the same thing and at times we were good and when we did that it was really easy to get in there, but at other times their defence just completely mucked us up so it's what we do in those situations."
The Taini Jamison Trophy final, which is likely to be contested between New Zealand and Jamaica, is now a must win opportunity for the Ferns if they want to head into the Commonwealth Games with any confidence.
Prior to the final, the Silver Ferns will face Fiji for their third match of the series at 8.10 tonight.
