PROMOTION-CHASING Selby RUFC raised their game in the second half to stave off the threat of a Roundhegians upset in Yorkshire Two.
The Swans trounced Roundhegians 57-12 at Sandhill Lane earlier in the season, but they turned around at 14-14 on Saturday before Selby came through 33-21 winners.
Selby were nearly ahead in the first minute after a charge down on the Roundhegians 22 but play was brought back and a penalty awarded to Roundhegians.
The visitors broke the deadlock on 11 minutes after full-back Dan Porter brilliantly turned defence into attack after fielding a deep kick into the Selby 22. He made 50 yards with a mazy run and prop Duncan Hardy scored under the posts. Josh Cruise converted.
Roundhegians levelled through winger Elliot Jackson, with scrum-half Alex Jones goaling.
The hosts led 14-7 after 28 minutes when centre Tim Smith hacked on and scored, with Jones again converting.
A minute before half-time, the Swans hit back as winger Ben Lunt and flanker Jacob Robinson put hooker Josh Greenfield in for the first of his hat-trick of tries, with Cruise converting.
Robinson and number eight Martin Protheroe paved the way for centre Sam Weller to cross on 43 minutes, but Jackson got his second try to the hosts and Jones put his side 21-19 up.
Heading into the last quarter, Selby were in the ascendancy for most of the last quarter and they regained the lead on 56 minutes with Greenfield scoring near the posts for Cruise to convert.
The Swans put the result beyond doubt when young winger Charlton McCoy made a brilliant run deep into the Roundhegians half before putting hooker Greenfield in for his third and Cruise again converted to keep Selby in second place behind leaders Doncaster Phoenix with two home games coming up.
