As we progress into June, the fantasy baseball landscape is evolving. The waiver wire is thinning, but there are still valuable players to consider adding to your roster. Key among them is Ronny Mauricio, whose recent call-up to the New York Mets has shown both promise and volatility. He’s currently rostered in just 16% of Yahoo leagues, making him a potential boom or bust candidate.

Another intriguing option is Ben Brown from the Chicago Cubs. After a rocky start, his recent performances suggest he's finding his groove, especially with a notable reduction in walks and an impressive strikeout rate. Lastly, Jeff McNeil, a consistent performer with the Mets, is also worth investigating as he continues to demonstrate an upturn in form since returning from injury.
