With Fantasy Baseball trade deadlines in the rearview mirror, you need to turn to the waiver wire in order to gain an advantage over your opponents. Unfortunately for those playing catch-up, time is running out and pickings are getting increasingly slim. There are a number of prospects that deserve to be September call-ups, like Javier Baez, Joey Gallo and the recently recalled Byron Buxton. After those obvious names, you can dig a little deeper with players like Dalton Pompey, Alex Meyer and Erik Johnson. For this list, however, we are only going to discuss players that have yet to make their major league debut. Robert Stephenson would have appeared here but an injury landed him on the Triple-A disabled list, likely ending his season. He is a name to track closely next spring, as he offers frontline upside and should have an opportunity to start immediately.
- Corey Seager (Dodgers, SS) – Jimmy Rollins has hit an improved .257 since the All-Star Break, a marked improvement over the .213 he hit before the break and somehow, he remains a fixture in the Dodgers lineup. Meanwhile down on the farm, Corey Seager continues to impress as a 21-year-old in Triple-A. He could eventually be a Top 5 contributor at the position, but even semi-regular playing time in September could lead to a Fantasy impact. Seager has developing power and strong hit tool, along with the athleticism to swipe double-digit bases on an annual basis. He is almost certainly going to be the starting shortstop on Opening Day next season. In the meantime, he should relegate Rollins to a bench role, effective immediately. He is worth snagging now if available, especially if you need middle infield help.
- Hector Olivera (Braves, 1B/3B) – The Dodgers signed the highly touted Cuban star this May and traded him to the Braves in July as part of the Alex Wood deal. Despite spending very little time in the minors, Olivera will likely make his debut in the coming weeks. If it weren’t for a lingering hamstring injury, he would presumably already be in Atlanta. The 30-year-old is major league ready with the bat and could provide impactful stats over the final month of the season. The Braves are in desperate need of firepower on offense and will give a healthy Olivera every chance he can to provide a spark. He and Freddie Freeman could be a nice foundation in the middle of their rebuilding lineup. It would be best to quickly grab Olivera off of your waiver wire now, because he should be up before September.
- Jose Berrios (Twins, SP) – As young starters get shut down or limited and veterans succumb to the grind of another long season, September call-ups can reinforce your staff. The righty has already eclipsed his career high in innings pitched, but could earn a few September starts for the Twins. Long-term he may be more of a SP2 than true ace, but either way he has impressive stuff and immediate impact potential. He is ready to pitch in the major leagues right now, and should get the chance in the coming weeks. Berrios could inject some major upside in a Twins rotation that lacks talent and healthy arms. With Buxton back up and Sano flashing big time power, Berrios and fellow rookie Alex Meyer represent key cogs in the youth movement happening in Minnesota.
- Orlando Arcia (Brewers, SS) – Oswaldo’s little brother offers an excellent glove and more recently, an improved hit tool during his ascent through the minors. Jean Segura’s struggles over the past two seasons have made him potentially expendable, largely due in part to Arcia’s development. The 21-year-old could develop into what the Brewers hoped Segura would be, a top of the lineup hitter who can disrupt on the bases. He is never going to be a slugger, but Arcia could develop surprising pop for the position. If called up, he could be looked at as a source of cheap speed and runs down the stretch. He will definitely be a Fantasy sleeper heading into next season, and a successful September call-up will only fuel the fire.
- Blake Snell (Rays, SP) – It may be a long shot, but Snell could be a huge piece for the Rays’ playoff run. If they are still in contention in a few weeks, expect to see Snell pitching in the majors. Pitching at three different levels this year, Snell has flat-out dominated the competition at each stop. He sports a 1.26 ERA and 141 Ks in 114 innings. The lefty has impressive stuff, led by a big heater that sits in the mid-90s regularly. While control has been an issue at times, Snell’s upside is very intriguing. He could be an asset for your Fantasy team based on strikeout potential alone. His play thus far this season is well deserving of a taste of big league life. You can likely grab him with a cheap waiver wire bid right now, and simply drop him if he isn’t called up this season.
