As fantasy baseball managers navigate the complexities of Week 13, several undervalued hitters are emerging as key waiver wire targets. Alec Burleson of the St. Louis Cardinals, rostered in just 55% of leagues, has displayed significant power with four home runs and 11 RBIs in his last seven games. Colton Cowser of the Baltimore Orioles, recovering from injury, has returned to the lineup with a .622 slugging percentage since June 2. Javier Baez, now a Detroit Tiger, is showing signs of a comeback, boasting a 125 wRC+ and contributing to the Tigers’ strong season. Trevor Story of the Boston Red Sox, while inconsistent, has recently picked up his performance, hitting four homers in June. Lastly, Jo Adell of the Los Angeles Angels has caught attention with his power surge, hitting 10 homers just this month. Each of these players represents potential game-changers as the fantasy season progresses.
