First Year Scholar Sinclair struck after 71 minutes with a fine angled drive to tie the scores at 2-2 but in fairness it was the home side that looked the more likely to claim victory throughout the afternoon.
Wednesday were dealt with a huge blow in the 20th minute when the returning skipper Guy Branston suffered a reoccurance of his recent foot injury and was replaced by Chris Carr but the home side to their credit attacked from the off having a number of chances notably from Matthew Hamshaw and Patrick Collins.
Sheffield born attacker Kevin Davies gave Bolton the lead five minutes before half time when he rose to head home a right wing cross by Ricky Shakes but the lead wasn't to last long as ex-Rangers forward Steven MacLean brought the Owls back on level terms from the penalty spot just two minutes later after Wanderers defender Danny Livesey was adjudged to have impeded the prolific forward.
Shortly after half time MacLean added his and Wednesday's second of the contest when he thumped a fine header past Kevin Poole in the Bolton goal. Ex-Manchester City ace Lee Peacock had provided a delightful assist for his fellow striker.
However it was Bolton who were to have the last word as substitute Sinclair, on for Davies gave the Lancashire side a share of the points. There is sure to be more to come from the Alnwick born striker who has already made his reserve team bow.
Ex-Wolves striker Adam Proudlock caused the inexperienced Bolton defence a few problems following his second half introduction but the Trotters can consider themselves lucky to get a share of the points.
This will no doubt have stood the young Wanderers team in good stead for the future as the Owls had quite a few known names in their team with league experience.
