Miami Marlins prospect Jonathon Long has four RBI and 14 runs scored in 13 games since joining Triple-A Jacksonville. Long was acquired by the Marlins from the Chicago Cubs at the trade deadline. In 99 games this season with Triple-A Iowa, Long hit .283 with 12 homers and 62 RBI to go with 67 runs scored. The 24-year-old infield/outfield prospect is the No. 19 prospect in the Marlins' system and has a 50-grade hit tool with 50-grade power. Long has the versatility to play either corner infield position along with the outfield, giving him a better shot at making his debut this season. With first baseman Kyle Stowers on the IL, that also gives Long a better shot at an MLB debut. The Marlins do have good outfield depth along with Javier Sanoja manning third base so Long will need to break through a bit for a big-league opportunity this season.

Seattle Mariners outfield prospect Lazaro Montes continues to show off his power stroke this season in the minors. Montes has eight homers and 18 RBI in August with Triple-A Tacoma and is up to 36 homers and 92 RBI between Double-A Arkansas and Tacoma this season. The left-handed hitter is the No. 5 prospect in the Mariners' system and has 65-grade power. Montes, signed out of Cuba, would offer nice power potential for fantasy teams if given a shot at promotion to Seattle. Fantasy managers can take a chance on Montes this season, but there is a good shot that he will not make his big-league debut until next season. At 21 years old, Montes could use a bit more minor league seasoning, but looks like a player who will make a big-time impact in the major leagues when he debuts.

Cleveland Guardians prospect Ralphy Velazquez has hit three homers in his last four games at Triple-A Columbus in what has been a scorching hot month of August for the left-handed hitter. Velazquez has 11 homers and 20 RBI this month with a .356 batting average and 17 runs scored. The 21-year-old has split time this season between Double-A Akron and Columbus and combined to hit .288 with 24 homers and 74 RBI. Velazquez is the No. 2 prospect for Cleveland and has 60-grade power with a 50-grade hit tool. If Velazquez keeps hitting at this pace this month, he should get a chance for a promotion to Cleveland. The Guardians could use the power upside that Velazquez brings and he would be a welcome addition to many fantasy teams late this season.

Miami Marlins outfield prospect Cam Cannarella is hitting .250 this month at Triple-A Jacksonville with no homers and one RBI in what has been an August that has lacked power for the left-handed hitter. The 22-year-old has shown little power in his 25 games with Jacksonville, hitting .264 with one homer and four RBI. In High-A and Double-A combined prior to his promotion to Jacksonville, Cannarella combined to hit 12 homers with 51 RBI. The outfielder is the No. 6 prospect in the Marlins' system and has a 55-grade hit tool with 60-grade speed. Cannarella is likely a year or so away from a promotion to Miami, so he can best be left on waivers in redraft leagues and is more of a dynasty league target. Miami has a deep outfield at the big league level, so Cannarella is not likely to break through this season to make a fantasy impact.
