Usually around this time every Saturday, you've found my top 10 prospects for the rest of this year, updated weekly for any call ups or demotions. With the September 1st roster expansion date coming up on Monday however, a large portion of any remaining call ups will happen within a few days of then, and as minor league seasons complete for affected players. With that in mind, here's a look at some of the prospects that are likely to be called up come Sunday, and whether they can have an impact for you in the final month of the season.
Potential High Impact
Carlos Rodon (CHW) - The idea that a player drafted in June could be called up seems absurd, and White Sox' GM Rick Hahn tried to throw some cold water on the idea, but it is still very possible that Rodon is in Chicago and could even be inserted into the rotation. He has mid-rotation upside right out of the gate, and potentially even more if he is put into the rotation.
Andrew Heaney (MIA) - As currently constructed, the Marlins will need a fifth starter on September 2nd, which would allow five days of rest for Heaney from his last start at AAA New Orleans (8/27).Very convenient, but it's possible that Brad Hand or Brad Penny are called on from the bullpen for that start as well.
Taijuan Walker (SEA) - Scott Weber does a really great job of outlining how Walker could be called upon to make a handful of starts down the stretch over at Lookout Landing, and I can see this happening provided the team calls him up as soon as Tacoma's season ends on the 1st.
Nick Kingham (PIT) - Kingham has to be added to the 40-man roster after the season by the Pirates, and given their current rotation (and some of the struggles that have happened at times with Liriano and Worley), I can see the Pirates bringing Kingham up and giving him a couple starts down the stretch.
Low Impact Based On Playing Time
Maikel Franco (PHI) - Franco has been hitting much better lately, showing the power potential as well as a high average. If it were a different organization, I wouldn't be particularly worried about the fact that Cody Asche is in his way given how Asche has hit, but the Phillies don't necessarily seem that likely to make that decision. Franco does need to be protected this offseason from the Rule V draft, so it wouldn't surprise me if the team brought him up for an extended look.
Joc Pederson (LAD) - It's already been reported that Pederson will be called up after Albuquerque's season ends on September 1st, but the question is whether or not he gets consistent playing time in the majors once there. I've talked all season about the fact that the Dodgers have too many outfielders for Pederson to get that playing time, and unless someone gets injured, it seems unlikely that Pederson plays more than 2-3 a week.
Alexander Guerrero (LAD) - Guerrero was also reported headed to Los Angeles after the 1st, but again the problem remains the same. Dee Gordon is playing everyday at second base, and the team has not been playing Guerrero at shortstop or third base particularly, so it seems most likely that Guerrero would be an additional bat off the bench and giving rest for Gordon down the stretch. Impact unfortunately unlikely to be large.
Daniel Norris (TOR) - Norris is rumored to be headed to the Majors once Buffalo's season ends, but it isn't clear if it will be in the rotation or not when that happens. I think it's more likely he is in the bullpen, making his fantasy impact negligible at best.
Unlikely to Have An Impact
Jose Peraza (ATL) - This is a bit of speculation on my part, as Peraza needs to be protected from the Rule V draft this offseason. He could be an interesting source of speed in deep formats if he is called up, having stolen 60+ bases each of the last two seasons.
