Detroit Tigers top pitching prospect Jackson Jobe (hamstring) touched 99 miles per hour on his fastball as he fired three scoreless innings in a rehab start Sunday for High-A West Michigan. Jobe threw 32 pitches (24 for strikes) as he struck out four with no walks. It was an encouraging sign as the talented right-hander works his way back from a hamstring injury. The 22-year-old is one of the top minor-league arms with a devastating fastball-slider combination. His progress this year has been stalled a bit because of his injury but he is on the mend and could reach Triple-A by the end of the season should he demonstrate full health. Next year could be the year for him in Detroit and he has the tools to contribute to fantasy teams right away.

Philadelphia Phillies outfield prospect Justin Crawford logged two hits, including a triple, for High-A Jersey Shore on Sunday. The No. 4 prospect for the Phillies is hitting .290 with four homers and 30 RBI to go with 24 stolen bases at High-A this season. The 20-year-old is a speedster just like his father and long-time big-leaguer Carl Crawford and possesses 75-grade speed. He also has a 55-grade hit tool, making him a nice fantasy prospect with the potential to contribute heavily in runs, average, and stolen bases. Crawford could be looking at a few more seasons in the minors but all signs point to a quick progression based on his performance at High-A this season.

New York Mets infield/outfield prospect Luisangel Acuna logged three hits for Triple-A Syracuse Sunday, extending his hitting streak to 10 games in a torrid stretch. During his 10-game hitting streak, Acuna has five multi-hit games. The 22-year-old is hitting .312 in June and has raised his season-long batting average to .271. The Mets No. 5 prospect has shown off the wheels with 26 stolen bases this year. His pure hitting ability and above-average speed make him a great future fantasy contributor. Acuna could get a look for New York at some point this season and when he does is worthy of waiver-wire consideration in leagues of all sizes.

Los Angeles Dodgers outfield prospect Kendall George continues to turn heads at Single-A Rancho Cucamonga with a very productive June. The 19-year-old is hitting .292 this month with 15 runs scored and five stolen bases. The Dodgers No. 10 prospect has a rare 80-grade for speed but that is coupled with 30-grade power. He doesn't have a home run to his credit this year. So, as a fantasy prospect, George is a bit of a rare breed with the potential to dominate the steals category. Because of his lack of power, he will also need to continue to hit like he is now in the minors and provide above-average production in runs and batting average. He is still ways away from making a big-league impact but is a name worth getting to know.

All signs are pointing to St. Louis Cardinals catcher Willson Contreras (forearm) being activated from the injured list and returning to the starting lineup ahead of Monday's series opener against the visiting Atlanta Braves. Contreras fractured his forearm on May 7 and was originally slated to return by the All-Star break. Instead, he could rejoin the team weeks ahead of his projected timetable. He went 1-for-5 in his sixth minor-league rehab game for Triple-A Memphis, and his true testing point was catching back-to-back games, which he did on Friday and Saturday. He came out of those games fine and escaped a scar on Saturday when he was involved in a collision at home plate. With Ivan Herrera (back) also on the IL, rookie Pedro Pages is likely to stick around as Contreras' backup moving forward.
