Anna Harrison has shown she still has all her netball skills as well as an uncanny ability to get inside a goal shooter’s head.

Anna Harrison’s first netball game in 16 months showed she’s lost none of her skills in getting inside her opponents’ heads.

Whether it’s with the hoist to block a shot, superb elevation, quick feet or extendable arms, the unpredictable Harrison knows the way to introduce doubt into a goal shooter’s game.

That experience proved invaluable in last week’s upset trans-Tasman netball league win over the Adelaide Thunderbirds.

The Mystics went deep into extra time before recording their first win of the season, a shock 71-68 victory over the defending champions.

The win broke the Thunderbirds’ 16-game winning run, as shooters Carla Borrego and Erin Bell struggled to shake the attentions of Harrison and goal defence Julie Corletto.

“You need to get in their heads early and create that pressure, but it’s definitely a team effort,” said Harrison, who has been kept from the court with a niggling foot injury after taking a year off for the birth of son Isaac.

The Mystics’ next game is a tricky fixture against the Queensland Firebirds in Brisbane on Sunday, and Harrison and Corletto face the extra challenge of negating long-reaching goal shooter Romelda Aiken.

“We know the Firebirds have a couple of tall targets in the background – it’s never a feel-good game for goal keep, I can tell you that,” Harrison said.

The Firebirds have struggled to replace influential goal attack Natalie Medhurst, lost to West Coast Fever, but Amy Wild is growing in confidence every week.

The Queenslanders also boast an intimidating defensive line-up, headed by the uncompromising Laura Geitz.

Harrison says the Mystics will need to improve their communication on transition and in the feed into the circle if they want to back up last week’s breakthrough win.

“It’s just building those links and having the confidence to let it go on attack,” she said.
