You’ve probably noticed but in case you haven’t, the Kansas City Royals have been playing good baseball as of late. The team is 16-14 over their last 30 games and 12-8 over the last 20. It has felt like night and day in comparison with how the Royals performed during the first two months of the season. So what has changed to cause all this winning?
The most obvious answer is the influx of young talent in the Royals lineup on a daily basis. Ryan O’Hearn, Adalberto Mondesi, Hunter Dozier and Brett Phillips have all become regulars for Kansas City and while a few of those names have been on the roster for months now, they have never looked as comfortable as they have recently. This change has not only been a spark for the lineup, but has really shifted the morale in the clubhouse.

It also helps that the offense has been one of the best in the league over this past month. The Royals are 1st in slugging and ISO(tied for the lead with Oakland and Toronto), 2nd in wOBA, BABIP and batting average, 3rd in WAR and RBI’s and 4th in wRC+, runs, home runs and OBP. They have the second best hard hit rate over that span and the 5th best win probability added in the AL. The offense is leading the way and producing at a level we really haven’t seen from Kansas City since 2015.
But maybe the most important shift has been the Royals increased emphasis on running the basepaths. The Royals are first in the league in stolen bases and BsR over the last month and fourth in Ultimate Base Running (UBR). Early in the season, Kansas City wasn’t running as often and it made sense why. At that point, the lineup was filled with older and slower players like Mike Moustakas and Lucas Duda, players who aren’t exactly known for their speed. Factor in the colder weather as well, and Kansas City was a very station-to-station team.

But in the last 30 days, the team has made speed a potent part of their offense. Whit Merrifield, Mondesi and Alex Gordon (yes, ALEX F. GORDON!) have all been taking advantage of their baserunning expertise and Whit is even tied for the league lead in BsR over that span. This has allowed the Royals batters more situations with runners in scoring position and given them more opportunities to drive in those runners. All this equals a greater chance for runs and the Royals have taken advantage of it.
So the offense has been a big part of the Royals recent success, but it isn’t the only element that has improved. Kansas City’s starting pitching has been just as vital for the team’s success as the bats. Over the last 30 days, the Royals starters have the 3rd best ERA, HR per 9 and HR/FB rate, 4th best WAR, WPA, BB per 9 and WHIP and 5th best FIP and xFIP. The Royals starters have thrown the 2nd most innings in that span (152.1 innings, only behind Cleveland) and while they haven’t been a dominating bunch (they’ve posted a 19.3% K rate in the last month, which is only 10th best in the league) they have found a way to get outs.

The most accurate representation of how they have been getting the job done would appear to be how the ball is being put into play. The Royals starters have allowed the third best ground ball rate and are 14th in fly ball rate, which is next to last. So they are making the opposing batters put the ball on the ground more, allowing the infield to be put to good use. The Royals have a very good defensive infield and it appears the team is working to their strength in that regard.
On the opposite end of that spectrum, they are not allowing as many fly balls which would also explain the lack of homers allowed. Many of the teams in the American League are built to be home run teams, so when that is stifled it would appear to be a big blow into their offensive output. It really appears like the starting pitching is working smarter, not harder.
Combine all of these efforts and you get a winning month for the Kansas City Royals. It appears that the shift to youth has been the right move for this franchise and hopefully is a springboard for expectations over the next couple of years.
What will be the most interesting aspect to follow is whether or not the team is able to take the experience from the last month and transfer that over into the 2019 season. While success in September should sometimes be taken with a grain of salt due to everything from roster call-ups to playoff teams resting their regulars more often, the Royals are doing a number of things right and it has led to success. This won’t mean the team will become a winning ballclub again next season, but it does create some hope and intrigue that wasn’t there just a few months ago.
