Ball dominated bat on the first day of Northern Districts' Plunket Shield match with Otago, as 15 wickets fell in Hamilton to leave play evenly poised at stumps.
The two teams combined for just 275 runs on a day that saw both sides' batsmen struggle to assert themselves on a testing pitch at Seddon Park.
The defending champions could manage only 204 in their first innings as Otago's bowlers earned the maximum four bowling bonus points, but the visitors' batsmen fared no better and ended the day on 71-5.
Volts captain Derek de Boorder won the toss and elected to bowl, a decision which soon paid dividends. The Knights were inactive in the first round of matches, and the rust appeared to show when Brad Wilson nicked one behind from the bowling of Jacob Duffy to fall for 10.
Fellow opener Joseph Yovich soon followed, with Ian Butler inducing an edge to reduce the home side to 55-2. Little did the Knights know, the second-wicket partnership of 37 was the best they would muster as Yovich's dismissal triggered a collapse which saw five wickets fall for 47 runs.
