An Alternative to the Cardinals
The St. Louis Cardinals might have a bigger ask than the Miami Marlins are able to accomplish for multiple player and with the injury plagued year Jazz Chisholm has had the Marlins need to invest in two bats to help them through the tough parts of their schedule. There are a few different hitters who could become available via trade, both the Washington Nationals and San Diego Padres should be sellers. How big of sellers might be a question but the Nationals have a solid outfielder that would make a big impact on the roster.
As we have looked at previously, Lane Thomas would be a stellar option for the heart of the Marlins lineup and would potentially be a more affordable option with a rebuilding Nationals team. Thomas is currently hitting .301 with 14 home runs, both of which would be huge adds for the Marlins lineup. Thomas has also driven in 45 so he would be one of the team leaders in home runs and RBI if acquired. I would go all in on getting Thomas and seeing if you can peel away an infielder from the Cardinals on top of it. Thomas can play right and DH, trading places with Soler on occasion.
The Padres might not sell much but they could trade starting pitcher Blake Snell. The Miami Marlins could use starting pitching depth with Eury Perez being limited for the rest of the season. Snell would add veteran presence and the pitching arm needed to help anchor the starting rotation. The Padres have said they will listen to offers for Snell. Marlins fans would cheer the move if Kim Ng can somehow acquire both Lane Thomas and Blake Snell. Time will tell but this option also knocks it out of the park.
