While Palace beat Wolverhampton Wanderers in their first Stateside friendly, their London rivals lost to new boss Julen Lopetegui's former club last week.
Match preview
After goals from Jeffrey Schlupp and Jordan Ayew put Crystal Palace two goals ahead in their most recent warm-up for the new Premier League campaign, teenager Asher Agbinone scored a third in Maryland, where Palace ultimately beat Wolves 3-1.
Palace are yet to lose since returning from their summer break, having previously played out a 1-1 draw with Charlton Athletic before posting an emphatic 6-3 victory over Crawley Town.
Since taking over from Roy Hodgson last term, head coach Oliver Glasner has made a significant impact, joining the capital club when they sat 14th in the table and leading them to a top-half finish with six wins and a draw from their last seven matches.
Despite losing Michael Olise to Bayern Munich this summer - while England duo Eberechi Eze and Marc Guehi are also in demand - the Eagles are intent on continuing that momentum during their first full season under Glasner.
After taking on West Ham - who they took four points off last term - Palace will conclude pre-season with a final friendly against Nantes next weekend, and their first Premier League fixture is away to local rivals Brentford on August 18.
Suffering his first defeat since being appointed West Ham United manager, Julen Lopetegui oversaw a painful 3-1 loss to Wolves last weekend, with his new side coming up short against the club he ditched on the eve of last season.
That reverse in flood-hit Florida followed a 2-2 draw with Ferencvaros and a 1-0 win over Dagenham & Redbridge, so the Hammers' results have been mixed so far this summer.
Despite finishing ninth in the Premier League and reaching the Europa League quarter-finals last term, Conference League-winning boss David Moyes departed by mutual consent, leaving behind a slim squad with an average age higher than most of West Ham's top-flight rivals.
In conjunction with technical director Tim Steidten, Lopetegui has already brought in former Wolves defender Max Kilman, Brazilian winger Luis Guilherme and goalkeeper Wes Foderingham, while deals for forward pair Crysencio Summerville and Niclas Fullkrug are apparently in the works.
As the ex-Spain coach's overhaul continues, two more friendlies - against Palace and then Celta Vigo - will set West Ham up for their season opener at home to Aston Villa on August 17.

Team News
After Michael Olise left Crystal Palace following a stellar 2023-24 season, Ismaila Sarr has been brought in to replace him, but the latter is not yet ready to make his club debut.
In addition, Jean-Philippe Mateta is with France at the Olympics, while Daniel Munoz and Jefferson Lerma are still on holiday following Colombia's Copa America campaign; England trio Adam Wharton, Marc Guehi and Eberechi Eze are also unavailable.
Having replaced Sam Johnstone against Wolves after his return from international duty, Dean Henderson seems to be Oliver Glasner's undisputed number one goalkeeper and should start between the posts on Saturday evening.
Meanwhile, West Ham welcomed Brazilian playmaker Lucas Paqueta to their Tampa Bay training base earlier this week, but he is not likely to be involved while building up fitness following the Copa America. Mexico midfielder Edson Alvarez suffered a hamstring injury at CONMEBOL's continental tournament so is also ruled out.
Long-serving left-back Aaron Cresswell captained the Hammers on Sunday, and he should again feature in a back four that may feature new signing Max Kilman for the first time.
Crystal Palace possible starting lineup:
Henderson; Richards, Holding, Riad; Clyne, Hughes, Schlupp, Mitchell; Kamada, Ayew; Edouard
West Ham United possible starting lineup:
Fabianski; Coufal, Aguerd, Kilman, Cresswell; Soucek, Potts, Ward-Prowse; Kudus, Antonio, Guilherme
