Craig McMillan believes Ross Taylor's magnificent double century at the Waca yesterday has been in the pipeline for a while.
Taylor starts the fourth day of the second test against Australia later today on 235, the highest of his 13 test centuries and, in batting coach McMillan's opinion, among the best by a New Zealand batsman.
"It was an immense innings and has been brewing for some time," McMillan said.
"He's been short of time in the middle, and runs. But what it is they say? Form is temporary, class is permanent.
"His concentration (Taylor has batted 20 minutes short of eight hours), his tempo were superb and his hitting straight down the ground is something he's worked really hard on to open up an area that hasn't always been a strength of his.
