Pablo Zabaleta was the first to react to a spilled ball by Ben Foster to head home from close range after just three minutes of play, and Sergio Aguero doubled the hosts' lead with a finely struck shot from the edge of the box after just 10 minutes of action.
West Brom's Graham Dorrans gave the visitors some hope when he took one goal back, but City defender Martin Demichelis restored the two-goal lead before half-time.
The second half was a quiet affair until David Silva went down awkwardly as he appeared to roll his ankle. The Spanish international was forced to leave the pitch on a stretcher and with his ankle wrapped in a plastic cast. He looked to be in obvious pain.

The visitors seemed to feed off the momentum created by the injury, but apart from a handful of half-chances, they never truly troubled Joe Hart as City held on for the win, keeping the team alive in the hunt for the title with just three weeks remaining in the season.
City were the winners of the match on paper but perhaps not in spirit, and Goal's Paul Macdonald wasn't even sure Manuel Pellegrini would be willing to comment on Silva's devastating injury:
FT. City 3-1 winners, but as for the injury cost - we'll see if Pellegrini wishes to comment— Paul Macdonald (@PaulMacdGoal) April 21, 2014
Per the Premier League's official account, the Chilean manager kept his comments on the player's injury brief:
Man City boss Manuel Pellegrini on David Silva's injury: "[He] has a problem with his ankle, we'll see [on Tuesday] how it is." #MCIWBA— Premier League (@premierleague) April 21, 2014
As shared by SB Nation's Ben Pugsley, Pellegrini said the player had previously complained about pain in his right ankle:
Pellegrini: "Right ankle on Silva, we see tomorrow, previous 3 games he has pain. Not sure if same problem and pain increased or new injury"— Ben Pugsley (@benjaminpugsley) April 21, 2014
If this injury is indeed related to the previous pain Silva mentioned, questions will be asked about Pellegrini's decision to play the midfielder against relegation-threatened West Brom.
With the title race still in full swing and a World Cup on the horizon, both club and player will have wanted to do anything possible to avoid any long-term injury. Starting Silva on the bench as a substitute if the team were in need of a spark against some of the league's lesser teams would have been a safer choice.
Per Macdonald, however, Aguero's substitution was just a precaution:
Pellegrini reckons Aguero will be ok, easing him back in after previous knock. Said first 20 mins was the "City of earlier in season"— Paul Macdonald (@PaulMacdGoal) April 21, 2014
Speaking about the title race, Pellegrini acknowledged Liverpool have their fate in their own hands but stated his team should continue putting pressure on the Reds:

Via the Premier League's account, Pepe Mel talked about next week's crucial match against West Ham, as West Brom look to avoid the drop:
West Brom boss Pepe Mel: "The next game is like a cup final and the whole year is based on this game against West Ham." #MCIWBA— Premier League (@premierleague) April 21, 2014
According to The Guardian's Daniel Taylor, West Brom could have some injury concerns of their own:

As shared by this fan, the Spaniard decided to have the interview done in Spanish once again, which is somewhat surprising since he has shown he is fluent in English in the past:
Pepe Mel the Baggies boss began his interviews in English and he wasn't bad - now he does them totally in Spanish with a translator lol !— Dermot Wynne (@afcderm) April 21, 2014
BBC WM's Richard Wilford heard the manager say Chris Brunt will be ready if called upon:
City will travel to London to take on Crystal Palace next week. The London hosts have been in fine form in recent weeks, having won five straight and claiming the scalps of Chelsea and Everton. Should Silva not be able to return for that match, City will have to look elsewhere for much of their creativity.
West Brom will take on West Ham, and with Cardiff, Fulham and even Sunderland all still very much alive in the race to avoid relegation, a result against the Hammers will be needed if West Brom want to play in the Premier League again next season.
