Three top fantasy baseball prospects are poised to make significant impacts and are worth considering for waiver wire pickups or stash options. Moisés Ballesteros, a catcher with the Chicago Cubs, has demonstrated exceptional hitting at Triple-A, holding a .334 average with 8 home runs and 50 RBIs this season. Samuel Basallo of the Baltimore Orioles has also impressed with a .265 average and 17 home runs and is seen as a potential call-up to fill the gap created by injuries to the Orioles' catching staff. Lastly, Spencer Jones of the New York Yankees has shown tremendous power at Triple-A, with an impressive .297 batting average and 21 home runs, although his path to the major league roster may be blocked at the moment.

As the MLB season reaches its halfway point, the catcher position has undergone significant changes in both prospect and dynasty rankings. Leading the way is Cal Raleigh, whose incredible power performance positions him at the top, while other previously established catchers see their values decline. Noteworthy prospects have emerged, indicating a shift in the future of the position.

Among those to consider acquiring are Agustin Ramírez of the Miami Marlins, who boasts impressive metrics with a solid average and power potential. Drake Baldwin of the Atlanta Braves is another name to watch, especially with the potential for increased playing time following any trades involving their current catcher, Sean Murphy. Conversely, selling opportunities arise with Moises Ballesteros of the Chicago Cubs due to his uncertain playing future.

As the second half of the MLB season unfolds, the catcher position has witnessed significant changes in player rankings, particularly in dynasty leagues. Cal Raleigh of the Seattle Mariners has emerged as a standout player, showcasing impressive power with a pace for a record-breaking season. Alongside him, rising stars like Agustin Ramirez and Drake Baldwin have caught the eye of dynasty league managers, offering potential for substantial returns. Meanwhile, established players such as Moises Ballesteros are seen as sell candidates due to uncertain roles in their teams. Eric Cross provides an in-depth analysis of prospects and dynasty rankings, recommending strategic buys and sells for savvy fantasy managers.

The Chicago Cubs are at a pivotal moment in their pursuit of a World Series title, and their deep farm system presents an opportunity that should not be squandered. With the likes of Kyle Tucker now in their lineup after being acquired from the Astros, the Cubs face crucial decisions regarding their top prospects. Key players like Moisés Ballesteros and Owen Caissie have garnered attention as potential trade pieces, while the presence of James Triantos and Kevin Alcántara adds to the intrigue. The question remains: will Cub's GM Jed Hoyer leverage these prospects to add vital pieces for a championship push?

Trading prospects can be a double-edged sword; it can yield an immediate impact player while also depleting future potential. The successful acquisition of Tucker from Houston, for instance, serves as a reminder of the rewards that come with taking calculated risks. With the clock ticking on the season, the Cubs must weigh the benefits of trading their top-tier talent against the risks of giving up future stars. A prudent approach is essential as they navigate these decisions in the coming weeks.

As fantasy baseball enthusiasts prepare for Week 15, several prospects have emerged as prime candidates to stash on benches or NA spots. Notable promotions from the minors include Colby Thomas, Harry Ford, and Colson Montgomery, all making their major league debuts recently.

Among the top prospects to watch, Samuel Basallo of the Baltimore Orioles has continued to shine, boasting a 147 WRC+ with 16 home runs. Despite injuries plaguing the Orioles' catcher position, Basallo remains uncalled. Meanwhile, Carson Williams of the Tampa Bay Rays is showing promise with 14 home runs and 14 stolen bases but is still working through adjustments at Triple-A. Moises Ballesteros of the Cubs has shown flashes of potential but needs opportunities to cement his role. Lastly, Chase DeLauter and Kristian Campbell are making strong cases for call-ups, with the Guardians and Red Sox potentially in need of their offensive contributions soon.
