3 MLB Prospects to Stash for Fantasy Baseball Playoffs

This MLB season has already seen a bunch of great prospects get the call for their big league debut, including a trio of second-generation talents on the Blue Jays in Vladimir Guerrero Jr., Cavan Biggio and most recently Bo Bichette.

The Dodgers bolstered their rotation this month with the addition of Dustin May, while Astros outfielder Yordan Alvarez is in the midst of a remarkable rookie season, including a recent three-homer game. If you own any of these guys in fantasy baseball, you're clearly happy with the results so far.

While most of the high-profile prospects have already been called up, there a few other big names down on the farm who may be added once rosters expand in September. Here are three names worth stashing, who can all pay huge dividends in the fantasy playoffs if and when they get the call.

3. Luis Robert, OF, Chicago White Sox

White Sox prospect Luis Robert has crushed it at two levels this season, as he is currently sporting a .339/.392/.621 line between Double-A and Triple-A. He has totaled 24 homers and 36 stolen bases so far, and offers some of the best power-speed upside in all of fantasy baseball. Robert does strike out a lot, but he has made so many other strides this year that it's easy to ignore the whiffs. The White Sox are usually more reserved with calling up prospects, but there is still a chance Robert can get a cup of coffee in September. If he does, he is a must-add in all fantasy leagues due to his five-category upside.

2. Gavin Lux, SS, Los Angeles Dodgers

It's crazy for a team that competes as much as the Dodgers to have such a loaded farm system, but that has been the case for years now. The team recently made two impact call-ups, in May (who secured his first big league win against the Marlins on Aug. 13) and catcher Will Smith, who is up to nine homers in 71 big league at-bats. If the Dodgers want to make one more monster addition to their roster, shortstop Gavin Lux lurks in Triple-A. He owns an absurd .358/.429/.628 batting line across two levels in the minors this year and is up to 55 extra-base hits in 411 at-bats. The Dodgers have been coy about his promotion, but he carries enough upside to warrant stashing, especially if your league has a spot for minor league players.

1. Carter Kieboom, SS, Washington Nationals

Of all the names on this list, Carter Kieboom has the best shot at a September call-up, as he already made his MLB debut earlier this year. While Kieboom struggled in 39 big-league at-bats, hitting just .128, he did slug a few homers. His play in Triple-A this season has been outstanding, as he currently owns a .309/.412/.518 batting line with 41 extra-base hits, as well as an impressive 87:59 strikeout-to-walk ratio. The Nats have a stud at SS in Trea Turner, but Brian Doizer has struggled as of late at 2B. Considering Kieboom can easily slide over to second, there is a strong chance he joins Washington in September for its postseason push.
