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.
