Santa Clara, CA - The San Francisco 49ers signed cornerback Chris Cook to a one-year contract Friday. Cook had spent his entire four-year career in Minnesota, where he racked up 120 tackles, 13 passes defensed and one sack in 34 games, including 29 starts with the Vikings. In 2013, the 27-year-old Virginia product posted a career-high 47 tackles while appearing in 12 games, including 11 as a starter. New Zealand Women all but secured top spot in Group A as they earned a third win in as many games with a six-wicket victory over Trans-Tasman rivals Australia, in Nagpur. The White Ferns eased home with 22 balls in hand after restricting the defending champions - at one stage 4-4 - to 103-8, their lowest score in World T20 cricket.But for Elysse Perrys 42, Australia - winners of the last three World T20s - might have struggled to reach the lowest Womens T20 ever made, that being Sri Lankas 57 against Bangladesh in October 2012.Meg Lanning chose to bat first but her team was on the back foot from the off against the triple-spin threat of Morna Nielsen (0-4 off four overs), Leigh Kasperek (3-13) and Erin Bermingham (2-23).Elyse Villani and Alyssa Healy fell to Kasperek in successive balls, failing to clear Lea Tahuhu at mid-on, before Meg Lanning was left stranded by Erin Osbournes poor call for a single. When Osbourne snicked behind on the drive, Kasperek had figures of 3-0 and Australia were staring at abject humiliation.But Perry carefully rotated the strike first in partnership with Alex Blackwell (10) and Jess Jonassen, striking three fours and a six before falling lbw to Sophie Devine - ball tracking indicating the ball would have gone on and missed leg.New Zealands chase received early impetus as Suzie Bates warmed to her task, pinching successive boundariies in Kristen Beams second over.dddddddddddd Kate Cross takes on the Sky Sports Five Ball Challenge... Together with Rachel Priest, Bates put on 58 for the first wicket in 7.5 overs before both fell in the space of three runs - Priest top-edging a slog-sweep and Bates sent back by Osbournes precise throw.Osbourne was back in the action, turning one past Sara McGlashans edge for Healey to pull off a neat stumping, but Australia simply didnt have enough runs on the board to prevent Amy Satterwaite from steering the White Ferns home off 16.2 overs.Watch highlights of New Zealands victory over Australia on Sky Sports 2 from 6pm, then join us for live coverage of England Women against India Women live on Sky Sports 2 from 9.30am on Tuesday.
