The countdown to the MLB playoffs intensifies with just two months left in the regular season, making it crucial for fantasy baseball managers to optimize their rosters. With the addition of players from the minors, this week's waiver wire targets include notable names such as Luke Keaschall, Andrew Vaughn, and Shane Bieber. Luke Keaschall, recently activated from the injured list, has made an immediate impact, hitting .444 with six RBIs in two games. Andrew Vaughn is also a strong contender with a consistent batting average, making him a valuable asset as managers push for playoff spots.

In addition to Keaschall, pitchers like Bubba Chandler and JoJo Romero are intriguing options. Chandler has shown promise with 20 strikeouts in Triple-A, despite a high ERA, while Romero's recent performances are worth monitoring. As teams expand their rosters, keeping an eye on these players can greatly influence fantasy outcomes. The landscape is ever-changing, and staying ahead in the waiver wire could be the difference come playoff time.
