When it comes to annual fantasy baseball sleepers, always a good place to look for undervalued and potentially high-impact players are on rebuilding teams. Like with the Houston Astros before their recent World Series run or the Philadelphia Phillies the last two years, teams that look like they are destined for a rough season often have some intriguing/young talent with some upside. Often these teams give younger players a chance to show what they can do and give them a longer leash to fight through any struggles unlike the New York Yankees and Boston Red Sox of the world. One such team in the former category for 2018 is the Kansas City Royals and they are prepared to give some unproven and young talent a chance to stick with the big club. This includes starting pitcher Jake Junis who has had a big spring training in registering a 1.80 ERA, 0.60 WHIP, and striking out 14 batters in 10 innings pitched. Just 25-years-old and a former 2011 5th round pick, Junis is opening some eyes in showcasing some potent strikeout potential which began to reveal itself in 2017 when he put forth a 10.90 K/9 rate at Triple-A. Junis get a promotion by the Royals off his 2.92 ERA at that level but he had mixed results. While Junis had good control with the Royals (2.29 BB/9), home runs were a big problem (1.37 HR/9) that helped balloon his ERA to 4.30. Be that as it may, Junis has become a potential late-round upside stab given the strikeout approach he has taken this spring and so feel free to add him to your cheat sheets for your draft.
