Last week it was announced that longtime Minnesota Twins stalwart Joe Mauer would be retiring after 15 seasons in the big leagues. When it became official, a small smirk spread across my face but not for the reasons you think. 

No, I don’t hate Joe Mauer; in fact it’s quite the opposite. I have immense respect for Mauer and everything he did in baseball. The smirk wasn’t even about Twins fans, as I have no issues with them either. I even feel their pain when it comes to Joe, since this is probably going to be eerily similar to what happens next year involving Alex Gordon.

No, I smirked because when I picture Mauer, I picture him getting another hit off of a Kansas City pitcher. I know it isn’t the truth, but it feels like he got a hit off of the Royals every time he came to the plate against them. So no, he isn’t hitting 1.000 off of Kansas City for his entire career, but it felt like it. 

It felt like it because Mauer owned the Royals. He was that guy who came up to the plate and in my brain I instantly thought ‘he’s going to get a hit right here’; more times than not he did. Lifetime against the Royals, Joe hit .319/.401/.442 with an OPS+ of 104.

But this got me to wondering what other players have owned Royals pitching over the years. I’m sure most of us can rattle off a few player’s names that always appeared to do damage against Kansas City, but will the numbers actually agree with our initial perceptions? 
  

I decided to set a baseline. I went with batters with 180 or more plate appearances against the Royals, since that would show a more consistent level of sustained success. While it might not be everyone’s first choice for determining success, I started with batting average:

Based on our criteria, Dustin Pedroia has the highest batting average against the Royals for batters with 180 plate appearances or more. Out of active players, Mike Trout is 9th, Jacoby Ellsbury is 10th (yes, he is technically still active), Adrian Beltre 19th and Erick Aybar 20th. A few other notables include Michael Brantley, Francisco Lindor and Ian Kinsler.

How about the most hits against Kansas City pitching?

While Hall of Famer Rod Carew leads the pack here, it’s interesting to see Victor Martinez right behind, trailing by only 11 hits. It makes more sense when you remember that Martinez played almost his entire career in the American League Central, playing for Cleveland or Detroit for 15 of his 16 seasons. 

Mauer sits in third here, followed by two Paul’s, Molitor and Konerko. When I started down this path, Konerko was one of the names that instantly popped in my head, so no real surprise here.

  Let’s move on to home runs:

Alex Rodriguez is a surprising winner in this category, hitting 50 career bombs against Royals pitching. Not surprising is Jim Thome in second with 49 and the dreaded Paul Konerko in third with 45 homers. For active players, Miguel Cabrera and Carlos Santana are tied with 27 long-shots, although one has moved on to the National League and the other has begun the downside of his illustrious career. 

In a bit of a shock, Grady Sizemore hit 25 career home runs off of Kansas City while posting an OPS+ of 131. Maybe it’s just slipping my mind but I don’t remember Sizemore being that much of a thorn in the Royals side.

Time now for the most total bases:

‘Royal Killer’ Paul Konerko compiled the most total bases against Kansas City at 418. He is followed by Cal Ripken Jr. with 410 and then A-Rod with 378. With Martinez and Mauer retiring, the highest total on this list for an active player is Cabrera with 322, followed then by notorious villain Ian Kinsler with 263.    

That leads us to the highest tOPS+ all-time against the Royals:

And the winner is….Gerald Laird? Okay, I figured at some point we would run across a name that came out of left field and we just got it. He is followed by a couple other odd names in Chris Singleton and Craig Monroe.

Diving deeper down the list, the highest active player is Dustin Pedroia at 147, and a few more notches down you get Erick Aybar at 145 and Carlos Santana at 144. With tOPS+ being an adjusted stat and not a cumulative one, it makes sense it would be the one with players that wouldn’t just pop into your head. But considering we are basing this off of more than 180 plate appearances, it is still impressive at what Laird, Singleton and Monroe did against the Royals over the years.

Finally, a look at the total offensive contribution with Runs Created:

A-Rod had the most Runs Created all-time against Kansas City with 170.9, followed by Jim Thome and Frank Thomas. Mauer is fifth with 145.4 and Konerko right behind him with 144.7. To find an active hitter you have to travel all the way down to 18th on the list, where Miguel Cabrera sits with  118.9.

In fact the next active player that currently resides in the AL Central (and that doesn’t mean current free agents, like Michael Brantley) is Jason Kipnis at 81 with 72.8. It looks like there will have to be a new crop of players to replace the guys like Mauer and Martinez who have been pouncing on Kansas City pitching for years. 

So what did this experiment teach us? For one, it shows us that we don’t need numbers to know that Mauer, Konerko, Martinez, etc., were abusing the Royals all these years. The eye test didn’t betray us in this regard.  

It has also showed us what the unbalanced schedule has done to skew the numbers on this list. While it’s understandable why MLB has moved away from the balanced schedule, you do wonder if some of these numbers would be different if each team didn’t play the other teams in their division 19 times each year.  

The perfect example is the total hits against the Royals. Would Victor Martinez only be 11 hits behind Rod Carew if they had the balanced schedule? Probably not. Could you imagine if Carew, after all those years with the Twins and Angels (who were in the American League West with Kansas City at the time) had played the Royals 19 times a season? It’s all a matter of preference, but the shift in the schedule does make one wonder what might have been.

What it does probably tell us is that the Royals having a lot of bad pitching over the last 20 years probably helped some of these numbers as well. It also tells me I won’t miss watching Joe Mauer spray hits into the outfield against Kansas City. Joe is a true baseball treasure, but he also owned a portion of the Royals, whether David Glass was aware of it or not.
