Yet the top two in England's second tier look increasingly likely to be the pair promoted to the Premier League, with third-placed Fulham suffering a damaging home defeat against Brentford.
In the first matches after the league's three-month coronavirus suspension, a new hero emerged for mid-table Derby County as 18-year-old Louie Sibley scored a hat-trick in its win at Millwall.
Rhian Brewster, a striker on loan from Liverpool, gave Swansea City's play-off hopes a boost by netting twice at Middlesbrough, while also making a powerful political statement.
POINT A MIXED BLESSING FOR BAGGIES
With Leeds in action at Cardiff City on Monday (AEST), West Brom had an opportunity to go two points clear of Marcelo Bielsa's team as the league resumed.
Bilic's players dominated the derby clash and had a host of chances but could not find a breakthrough, and a stalemate at the Hawthorns potentially plays into the hands of Leeds.
The top two are now level on points, with West Brom top on goal difference, but Leeds will have the chance to go three clear before the next round of games.
BEES STING NEIGHBOURS
Said Benrahma and Emiliano Marcondes scored late for Brentford in a 2-0 win at promotion rival Fulham, a result that leaves West Brom and Leeds seven points clear with eight games remaining for the play-off pack.
Nottingham Forest was heading for victory at Sheffield Wednesday after Joe Lolley gave the visitors a 69th-minute lead, only for Connor Wickham to grab a stoppage-time leveller for the Owls.
Forest sits fifth, four points clear of a Preston North End side which was held 1-1 at Luton Town, Callum McManaman firing a late equaliser for the hosts, who nevertheless fell to the foot of the table.
Blackburn Rovers beat Bristol City 3-1 in a battle between teams fighting with Preston for sixth place, but the individual performance of the day came from Sibley, whose heroics guided Derby to its 3-2 win at Millwall.
"I'm absolutely buzzing," Sibley said after the game. "To get that hat-trick was just unbelievable. When the third goal went in, I couldn't stop smiling."
Brewster was not far behind, his double steering Swansea to a 3-0 victory at lowly Middlesbrough.
Brewster held up a shirt that read "our colour is not a crime" after his first goal, expressing support for the Black Lives Matter movement.
TIGERS ON THE SLIDE
Wigan Athletic was a 2-0 winner at fellow struggler Huddersfield Town, while Hull City slipped into the bottom three after losing 1-0 at home against Charlton Athletic.
Barnsley climbed off the bottom by winning 1-0 at Queens Park Rangers, and Stoke City drew 1-1 at Reading.
