As we approach Week 9 of the fantasy baseball season, savvy managers should keep an eye on a selection of undervalued hitters who have been making waves but remain under-rostered. Gabriel Moreno, the catcher for the Arizona Diamondbacks, has been hot at the plate, boasting a slugging percentage of .708 over the last seven games. His overall numbers include a .276 batting average and 15 RBIs, making him an intriguing option for teams in need of catcher depth.

Meanwhile, Connor Norby of the Miami Marlins, recovering from an oblique injury, has shown significant potential with a .285 average and 110 wRC+. Brett Baty from the New York Mets has revitalized his career with a .296 average since his recent recall, while Carlos Narvaez of the Boston Red Sox has emerged as a standout catcher, providing solid offensive stats. Finally, Kody Clemens of the Minnesota Twins is finding his stride with impressive numbers after a trade from the Phillies. These players represent excellent waiver wire targets for teams looking to bolster their rosters.
