New South Wales 4 for 201 (Patterson 54) trail 7 for 431 (Gotch 100*, Maddinson 95, Dean 71) by 230 runs
Wil Parker, the 17-year-old debutant legspinner, claimed two big scalps to keep Victoria on top against New South Wales at the SCG after Seb Gotch had scored his maiden first-class century.
Victoria declared on 7 fo 431 shortly before lunch moments after Gotch had brought up three figures. The New South Wales openers departed after a half-century opening stand but Kurtis Patterson, playing his first Shield match since October, and Moises Henriques both looked in fine form as they added 102 deep into the final.
Then Parker, who had bowled nicely in his first spell, returned to manufacture back-to-back breakthroughs. His maiden first-class wicket came when he slid a delivery across Patterson as he came down the pitch, the ball grazing the edge before Gotch completed the stumping. In his next over he then benefited from some significant fortune when Henriques bottom-edged a pull into his leg which ballooned to slip.
Daniel Solway and captain Peter Nevill saw out the rest of the day but New South Wales have a lengthy tail so there was considerable work to do.
Gotch and Travis Dean had resumed with Victoria well placed on 5 for 318 and carried their stand to 150 in 50 overs with Dean making his highest first-class score in 21 innings after retiring hurt yesterday following the blow in the box from Trent Copeland.
Dean eventually fell when he top-edged a sweep off Steve O'Keefe while Gotch continued to carefully accumulate towards his hundred having twice fallen shortly previously in his career. The century arrived from 241 balls with a single off Liam Hatcher.
Armed with a new Duke ball, Victoria's seamers found early movement - Gotch had a difficult time behind the stumps - but it took a while to break through as Daniel Hughes and Nick Larkin settled in. Scott Boland claimed the first breakthrough when he trapped Larkin lbw then Will Sutherland, who began with four consecutive maidens either side of a brief rain delay, produced an excellent delivery to beat Hughes' inside edge.
Patterson, recovered from the quad strain which has disrupted his season, was soon into his stride has he played elegantly off front and back foot while Henriques continued the form he showed before the Big Bash. However, just when they were taking the competition leaders into a position of parity, Parker popped up to produce a moment he'll remember.
