With the Kansas City Royals having seen veteran bats such as Eric Hosmer and Lorenzo Cain exit stage left during this past winter due to payroll constraints, spring training 2018 was going to be about taking a look at some of the team's more highly-acclaimed prospects with an eye toward them possibly contributing at some point during the year. One of those prospects was first baseman Ryan O'Hearn who was originally just an eighth-round pick of the team in 2014 but who since that time has developed into a very potent power hitter in the minors leagues. After cracking 18 home runs at Triple-A a year ago in 463 at-bats, O'Hearn took that thump to 2018 spring training as he began hitting tape-measure shots all over Cactus League fields. The latest gem came Thursday when O'Hearn hit not one but two home runs as the 24-year-old hints that he could be a key contributor before too long. Right now the current plan for O'Hearn is for him to begin the year in the minor leagues but not much stands in the way of the team giving him a promotion before too long. O'Hearn has easy power that could result in 20-25 home runs right out of the gate and that would be his key fantasy baseball contribution since his average lags behind right now given some strikeout problems. Especially in AL-only formats, O'Hearn should be someone who is placed in the middle of your prospect lists for the upcoming fantasy baseball season given the fact he has a clear path to getting onto the field at some point given the power bat he brings to the table.
