Zoltan Gera opened the scoring in the 43rd minute when he lashed home a ferocious shot from the edge of the area, before the Reds were reduced to ten men shortly before the hour mark when Daniel Agger was given a straight red for a last-man foul on Shane Long.
Long stepped up but sent a feeble attempt straight at Reina, although he immediately made amends when he drew another foul inside the area from Martin Skrtel, allowing Peter Odemwingie to plant an emphatic effort into the bottom corner.
And 13 minutes from time, the Baggies wrapped up the win when substitute Romelu Lukaku headed home from close range after a delightful cross from the left by Liam Ridgewell.
Here, we take a look at the movers and shakers from Saturday's game at the Hawthorns.
Ben Foster - 6.5
Apart flapping at a number of high balls, Foster put in a solid display and made a couple of smart saves to deny Luis Suarez.
Steven Reid - 7
An impressive performance from the rampaging right-back who was solid in defence, but also ever-ready to support his team-mates when they pushed forward in attack.
Gareth McAuley - 7.5
At times, McAuley showed no regard for his own safety as he launched himself at everything Liverpool fired in at the Baggies goal.
Jonas Olsson - 7
The Sweden international wasn't as impressive as his partner in the heart of defence, but he did exhibit good reading of the game and put in a couple of timely interceptions in the defensive third.
Liam Ridgewell - 7
Ridgewell's tendency to dive in was exposed again on Saturday as he made a couple of clumsy challenges in needless situations, but he showed plenty of endeavour and was surprisingly dangerous going forward.
Claudio Yacob - 8
A classy debut from the Argentinean, who excelled as a deep-lying playmaker. Yacob hardly misplaced a pass all afternoon long, and often got his side on the front foot with short, simple passes.
Youssuf Mulumbu - 7.5
Mulumbu really excelled once Liverpool were reduced to ten men and began to influence proceedings in the middle of the park. The Congolese international proved an impenetrable wall in front of the Baggies defence, and nonchalantly broke down any attack the Reds tried to muster.
Zoltan Gera (off 69') - 8
Following a wretched run of injuries last season, which restricted him to just three Premier League appearances, it was good to see Gera back in action. And the Hungarian could not have marked his return in a better way than opening the scoring with a sizzling strike from the edge of the area that left Reina grasping at thin air.
James Morrison (off 81') - 8.5
Morrison put in a man-of-the-match performance as he tore the opposition defence to shreds with his tireless running. The former Middlesbrough man ran with intent every time he picked up the ball, and more than held his own against his more-illustrious opponents.
Shane Long (off 68') - 7
The Republic of Ireland international started the game brightly and threatened the visitors' goal with a number of half-chances, and he earned himself a terrific chance to score in the 58th minute after he was brought down by Agger in the box, following a clever off-the-ball run that was picked out by Morrison.
However, Long failed to reap the rewards of his own good work when he sent a pathetic attempt straight at Reina, although he made amends shortly after when he won another penalty after nicking the ball of Skrtel, highlighting how important his endeavour is to his side.
Peter Odemwingie - 7
A quiet game from the Nigerian, who spent much of the summer attempting to manufacture a move away from the Hawthorns.
Nonetheless, he did come to the fore when he mattered, and doubled West Brom's lead from the spot with an emphatic effort into the bottom corner, just minutes after Long had mucked up his attempt.
Romelu Lukaku (on 68') - 7
Based on this display, it's hard to see why Lukaku wasn't given a chance at Chelsea last season. Winning the ball off the on-loan striker proved a near-impossible task for the Liverpool players, who struggled to cope with his sheer pace and strength.
The 19-year-old also showed good awareness to pop up in the right place at the right time to nod home the hosts' third goal from close range 13 minutes from time.
Marc-Antoine Fortune (on 69') - 6.5
Fortune didn't exactly have a lot of time to impress, but he showed good pace on several occasions when West Brom were looking to hit their opponents on the counter.
Chris Brunt (on 81') - N.A.
The veteran came on late in the game and had insufficient time to make an impact.
Pepe Reina - 6.5
Reina was unlucky to have conceded three goal as he actually didn't have a bad game. Unfortunately for the Spaniard, he was let down by his defence on far too many occasions, something which happened frequently last term.
Martin Kelly - 7
While he was the youngest member of the backline that Rodgers started with, Kelly was one of the better performers and he showed maturity beyond his years with his reading of the game.
However, the England international does lack genuine pace and can be exposed by the nimblest of wingers, something the Premier League has in abundance.
Daniel Agger - 5
Given recent rumours linking Agger with a move to Manchester City, it was good to see the Dane start alongside Skrtel in the heart of the Reds defence.
However, it all turned pear-shaped two minutes before the hour mark as Agger was left with no choice but to bring Long down in the box after his defence had been sliced open, resulting in a penalty and a red card.
Martin Skrtel - 6
Skrtel was one of the league's best centre-backs last season, but it was a poor day at the office for him at the Hawthorns.
The Slovak struggled to cope with the pace of Odemwingie and the movement of Long, and spent much of the game chasing shadows, something you don't often see from Liverpool's rock at the back.
Glen Johnson - 7
While he's most often been deployed as a right-back throughout his career, Johnson has no problems playing on the opposite flank when called upon, something he proved again on Saturday as he energetically bombed up and down the left wing.
However, he didn't receive sufficient support from his team-mates, and couldn't do much on every occasion he was left stranded by the corner flag with two West Brom defenders bearing down on him.
Lucas (off 69') - 5.5
In his defence, Lucas has only just recovered from a long-term injury and was expected to take some time to get accustomed to the rigours of the Premier League.
Still, he looked severely off the pace against the Baggies and will need to improve soon if he wants to keep his place in Rodgers' starting XI.
Joe Allen - 7.5
A fine display from the Welsh midfielder, who was Liverpool's best player on the day.
Allen was tidy with his distribution and also tracked back to help out his defence when their opponents pushed forward, and already he looks like he could make a bigger contribution than Jordan Henderson did for all of last season.
Steven Gerrard - 6.5
Gerrard struggled to exert his influence on the game, although his cause wasn't helped with the strange formation Rodgers opted for.
At times, the Reds talisman was deployed in his favourite central-midfield role, but the lack of a left-winger meant he often had to drift out wide to provide an option, immediately negating his ability to run the show in the middle of the park.
Stewart Downing (off 60') - 4
Within five minutes of the start, it began to look as though Downing had finally arrived as he picked up the ball down the right and whipped in a dangerous cross on his weaker foot into the box.
However, that was the sole highlight in what was another awful display from the winger, who never looked up to see if he had a man to lay the ball off to, and instead insisted on running straight for the byline, before whipping in terrible cross after terrible cross.
Luis Suarez - 6
Like Downing, Suarez started brightly but while he is indeed one of the best players in the Premier League, it remains to be seen if he can be considered one of the best strikers, as he missed a number of gilt-edged chances to put his side ahead.
Fabio Borini - 6
A decent debut from the ex-Roma man, who made a couple of intelligent runs that were reminiscent of a certain Filippo Inzaghi.
Jamie Carragher (on 60') - 6
The veteran was brought on after Agger was sent off to shore up the Reds backline and did a decent enough job.
Joe Cole (on 69', off 78') - N.A.
You have to feel for the ex-West Ham wonderkid as he was handed his chance to re-establish himself under Rodgers, only to limp off with a hamstring injury after nine minutes.
Andy Carroll (on 78') - N.A.
It remains to be seen what kind of role Carroll will play at Anfield this season as he was only brought on with 12 minutes remaining, after the Baggies had taken a 3-0 lead.
