Wrexham claimed their first Championship victory of the season with a 3-0 win over injury-plagued Millwall on Wednesday. The Welsh club had previously drawn with Cardiff and Watford before losing at home to Birmingham in their last match. However, they bounced back strongly in south London, reigniting their push for promotion to the Premier League after narrowly missing the playoffs last season. The first goal came from a defensive error, as Millwall's Zak Sturge accidentally scored an own goal by deflecting Issa Kaboré's cross. Wrexham's striker Kieffer Moore added a second goal from 20 yards shortly after the break, and Jacques Ekomié sealed the win with a close-range finish. Millwall, who had started the season with two clean sheets against Bristol City and Norwich, have now conceded eight goals in their last two games. They were heavily defeated 5-1 by Southampton on Saturday. Millwall's struggles were compounded by injuries, with striker Josh Coburn and midfielder Casper De Norre ruled out during the match. Their fitness issues have worsened as Nigeria winger Femi Azeez left the club for Brighton in a £15 million transfer just 24 hours earlier. Rumarn Burrell scored both goals as QPR defeated Cardiff 2-1 at Loftus Road, extending their strong start to the season. Perry Ng scored a goal for Cardiff, but it wasn't enough to stop Julien Stéphan's second-placed team from moving to 10 points from their opening four matches. Ugo Raghouber scored his first goal for Burnley, earning them only their second point from four matches as they came from behind to draw 1-1 with Middlesbrough at Turf Moor. The French midfielder, who joined from Lille in July, scored an equalizer in the 54th minute after a pass from Zeki Amdouni. Aidan Morris had put Middlesbrough ahead in the 23rd minute, scoring his first goal after more than two years at the club with a stylish finish from 20 yards. Burnley, who were relegated from the Premier League last season, are going through a difficult period. They recently suffered a 4-1 loss at Norwich and lost Dutch forward Zian Flemming to Ipswich on transfer deadline day. Meanwhile, Charlton maintained an unbeaten record after Tyreece Campbell's second-half goal secured a 1-1 draw at West Brom. Nathan Jones's side fell behind to a powerful strike from Callum Styles just before the hour mark but equalized on 69 minutes with Campbell scoring from close range.
