Francisco Lindor and Miguel Sano are not only two of the top contenders for the American League Rookie of the Year Award, but are also two of the key X-factors who will determine which clubs snag the final 2015 MLB postseason spots.
When it comes to singling out X-factors, the main rule is that the given player can't be the biggest star of his team. Instead, the idea is to focus on guys like Lindor and Sano who could potentially have a decisive impact, but whose influence will be difficult to predict.
For Lindor and Sano, it's challenging to forecast just how crucial of a mark they'll make during the stretch drive because both players have extremely limited big league resumes.
