MLB 2017: One X-factor for each team
Kansas City Royals: 3B Mike Moustakas
“Moose” had an injury-riddled 2016 season, with a fractured left thumb and then a torn right ACL in May limiting him to 27 games (104 at-bats), seven home runs and 13 RBI. He earned the first All-Star selection of his career back in 2015, with a .284/.348/.470 slash-line, 22 home runs and 82 RBI, so entering the final year of his contract 2017 is a critical season for Moustakas.
The Royals have a couple other key players entering their contract year, in first baseman Eric Hosmer and center fielder Lorenzo Cain, but a strong argument can be made that Moustakas is equally as important to any chance the team has to rebound back to playoff contention this year. I would actually make the case Moustakas is the most important player for Kansas City, with the unproven Hunter Dozier as is back up. A significant drop-off is virtually assured if Moustakas misses substantial time again.
Moustakas, as expected less than a year removed from his torn ACL, is being brought along slowly thus far in spring training. But if he can say healthy, a walk-year motivated Moustakas is an obvious huge x-factor for the Royals in 2017.
