Bolton legend John McGinlay became the unwitting figurehead for fans’ protests as thousands of Wanderers supporters voiced their anger at controversial owner Ken Anderson last night. But on the field the struggling Lancashire club slumped a step closer relegation thanks to goals in each half from Jay Rodriguez and Scott Field. Former Bolton favourite McGinlay was banned from the ground and his role as local radio pundit for the meeting with promotion-chasing Albion after making critical comments about Anderson’s reign in charge. From a yard out, Jay Rodrguez steers home Craig Dawson's header for the opening goal MATCH FACTS BOLTON: Alnwick, Taylor, Beevers, Hobbs, Olkowski, Ameobi, O'Neill, Lowe, Noone (Pritchard 82), Murphy (Buckley 68), Donaldson (Magennis 68) SUBS NOT USED: Matthews, Wilson, Wheater, Connell BOOKED: Olkowski, Donaldson WEST BROM: Johnstone, Holgate, Dawson, Hegazi, Gibbs, Barry, Harper (Adarabioyo 90), Brunt (Field 26), Robson-Kanu (Sako 85), Gayle, Rodriguez SUBS NOT USED: Bond, Bartley, Hoolahan, Leko BOOKED: Barry, Holgate GOAL: Rodriguez 19, Field 75 Championship Premier League Championship League One League Two Scottish Premiership Scottish Div 1 Scottish Div 2 Scottish Div 3 Ligue 1 Serie A La Liga Bundesliga The pre-planned demo saw up to 3,000 Bolton fans gather outside the stadium an hour before kick-off, chanting McGinlay’s name and demanding Anderson leaves their club. They also marched around the ground, joined by McGinlay himself, in a loud but peaceful protest against Anderson, who claims to be talking to two potential new buyers for the former Premier League club. Protesting fans with banners also congregated inside the ground and a handful threw tennis balls onto the field as the televised game was about to kick off, delaying the start by a few seconds. It was a night that had an air of simmering tension about it but Bolton fans were quickly focused on the field of play, rather than the boardroom, when Gary O’Neil glanced just wide from Craig Noone’s third minute cross. Trotters' fans held peaceful but vocal protests outside the stadium before the game The supporters were calling for controversial owner Ken Anderson to leave the club The protests continued into the ground as supporters chucked tennis balls to delay the match Sadly for the long-suffering Bolton supporters, it did not take long for the division’s leading scorers to click through their attacking gears. After seven minutes, in-form Dwight Gayle set himself up for a chance with neat control and a volley which whistled just past Ben Alnwick’s far post. And, on 18 minutes, Darren Moore’s side took a deserved lead after Jason Lowe had made a clumsy foul on Hal Robson 30 yards from goal. Chris Brunt curled in a far-post free-kick for Craig Dawson who outjumped his marker and headed goalwards before team mate Rodriguez made certain the ball crossed the line by nodding in from under the cross-bar. The frustrations continued for the section of the most vocal dissenting fans and, just before the half-hour, a number of them were engaged in scuffles with club stewards as the anti-Anderson clamour grew and officials tried to remove banners. The former Southampton striker enjoys his moment as he grabs a 14th goal of the season West Brom attacker Hal Robson-Kanu is bandaged up after suffering a nasty head injury Again, the protests seemed to have a galvanising effect on Wanderers, however, and within moments Jack Hobbs’ cross picked out Sammy Ameobi whose 16-yard shot had to be tipped over by Sam Johnstone. And when the persistent Wanderers fans managed to unfurl a new banner on the upper deck of the stand, they at least had something to cheer about for the first time since the opening minutes. Bolton supporters nearly had something even more important to cheer about in the opening moments of the second half when Johnstone again leaped into action, this time to palm away a Lowe header from Noone’s corner. And a gutsy second half showing gave Phil Parkinson’s side hope of an equaliser. Youth graduate Sam Field came off the bench and was on hand to fire home the second The midfielder has made just one start this season and bagged his second ever senior goal Ahmed Hegazi might have settled West Brom nerves from a well-worked corner from first half sub Field but his shot sailed harmlessly over. And on 75 minutes, first half goalscorer Rodriguez did precisely that with the pass that set up the decisive second goal. His ball was cleverly dummied by Gayle, catching the Wanderers defence flat-footed in the process, and Field was in the clear to make a confident finish past the home keeper. It was a wildly popular goal among visiting Baggies fans as the 20-year-old claimed just the second league goal of his hugely promising fledgling career.
