On the Scale of Self-Assuredness (where 0 = Just Spitballin’ and 10 = I’ve Got It!), writer rates this idea as a 7.
Major League Baseball continues to thrive by a number of measures, but a few troubling trends are worth addressing to ensure the game’s long-term health. Specifically, MLB justifiably seeks to shorten the overall length of games and/or improve the pace of games, and to increase the percentage of balls put into play (or conversely, to reverse the rapidly rising percentage of at-bats that end with a strikeout, walk, or home run).
Many believe that an adjustment to the strike zone could directly lead to more balls being put in play, which would indirectly lead to quicker and more exciting games. However, there is significant disagreement about what adjustment would be most effective. Some say that shrinking the strike zone is the way to go (to give batters an advantage), while others say that enlarging the strike zone is the way to go (to give pitchers an advantage), while still others say the strike zone should be left alone.
It’s easy to see the possible upside to each argument. Then again, it’s easy to see a possible major unintended consequence. A smaller strike zone might compel pitchers to throw more pitches that are easy for batters to drive. Then again, a smaller strike zone might make batters pickier, compelling them to take more pitches (leading to longer at-bats and more walks). A larger strike zone might force batters to get the bat off their shoulder. Then again, a larger strike zone might lead to even more called strikes and swings and misses (and consequently, strikeouts) than we already see. Leaving the strike zone alone is the least controversial approach, but would do nothing to address the sport’s primary concerns.
Smaller, as-is, or larger – so who’s right? Maybe all three. Maybe there’s a way to offer batters an advantage early in each at-bat, and to offer pitchers an advantage late in each at-bat, to encourage batters to put the ball in play early in an at-bat.
MLB could INTRODUCE THE DYNAMIC STRIKE ZONE CONCEPT, where the strike zone starts small for every at-bat, then expands slightly after Strike 1, then expands slightly again after Strike 2. With this concept, batters are likely to see the most favorable pitches early in an at-bat, and would change their approach accordingly.
Some impressions and considerations:
- What would the strike zones be?
Maybe (I’m not married to these at all)…
- With 0 strikes:
- Top: Belt
- Bottom: Top of knees
- Inside: More than half of ball must be over plate
- Outside: More than half of ball must be over plate
- With 1 strike:
- Top: Midpoint between shoulders and belt (current location)
- Bottom: Center of kneecap
- Inside: More than half of ball must be over plate
- Outside: Any part of ball must be over plate
- With 2 strikes:
- Top: Armpits
- Bottom: Hollow of knee
- Inside: Any part of ball must be over plate
- Outside: Any part of ball must be over plate
- Wouldn’t this necessitate an automated strike zone?
Yes (which I favor anyway). There’s an added beauty because this could serve as the ultimate selling point for the Commissioner that MLB must adopt an automated strike zone (it’s unreasonable to implement the dynamic strike zone concept without it). The home plate umpire would still be needed for his many other responsibilities (including signaling – not judging – balls and strikes), and could now focus more intently on enforcing pace-of-play rules.
- How would the automated dynamic strike zone adjust from pitch to pitch?
The automated static strike zone (the form commonly discussed and proposed) would have to adjust settings from batter to batter (Jose Altuve Mode, Aaron Judge Mode, etc.) anyway, so I reckon the automated dynamic strike zone would adjust settings in a similar way from pitch to pitch (Jose Altuve – 0 Strike Mode, Jose Altuve – 1 Strike Mode, etc.)
- What would pitchers think of the change?
Overall, pitchers should probably see it as a wash. If a pitcher can walk across the hot coals of the tiny zone associated with the first strike, then things return to normal to get the second strike, and he can then go for the kill with the generous zone associated with the third strike.
Also, for better or worse, if more at-bats end quickly, starting pitchers are likely to remain in the game longer.
- What would batters think of the change?
This is where it gets really fun, because this might have a really cool effect on batters’ approach at the plate
- In the last few years, many batters swing for the fences, and they get three essentially-the-same chances to connect. With the dynamic strike zone concept, batters know the best pitch to hit is likely to come early. Do they still swing from the heels? If they don’t connect on that first swing, then their challenge gets tougher and tougher as the at-bat progresses. The dynamic strike zone concept just might be the force that compels batters to cut down on their swing and put the ball in play
- Over the last generation, greater value has (rightly) been placed on drawing walks. Many batters even step into the box seeking to work a deep count and take a walk if it comes. With the dynamic strike zone, I’m not sure any batter will step into the box looking to draw a walk, or even to work the count. This concept just might be the force that compels batters to swing the bat at all
- CURRENTLY, BATTERS ENJOY THE GREATEST LIKELIHOOD OF FACING A FAVORABLE PITCH BY WATCHING THE BALL TALLY INCREASE OVER THE COURSE OF THE AT-BAT. UNDER THE DYNAMIC STRIKE ZONE CONCEPT, BATTERS WOULD ENJOY THE GREATEST LIKELIHOOD OF FACING A FAVORABLE PITCH BY PREVENTING THE STRIKE TALLY FROM INCREASING OVER THE COURSE OF THE AT-BAT
- It’s very possible batters could be the concept’s biggest beneficiaries (by giving them a very hittable pitch early in most at-bats) and harshest critics (through a distaste – understandable to an extent – for having to adjust to different strike zones, requiring them to adjust their vision and aggressiveness from pitch to pitch; I would argue that they do this already, in part due to the human element of umpiring, and in part due to strategy and natural tendency – “expanding” the zone after each strike)
- What would fans think of the change?
To bring it back around to the original aims of addressing pace/length of game, and reducing three-true-outcome at-bats, I think the dynamic strike zone concept could be the best of many worlds. I think it would:
- Very likely increase balls in play (hopefully with more non-home-runs)
- Very likely reduce walks
- Very likely shorten length of game
- Not necessarily have any effect on pace of game (this factor would still be dependent on pitchers, batters, and umpires honoring pace-of-game rules)
- Probably(?) reduce home runs. I’m not sure if batters would cut down on their swing early in the at-bat (knowing that pitches get tougher as the at-bat progresses), or swing from the heels early in the at-bat (knowing that’s when they’re likely to see the best pitch to crush)
- Probably reduce strikeouts. More at-bats will end early, so this will reduce strikeouts overall. However, if you break it down to strikeouts after the count reaches two strikes, the strikeout rate in this particular category will probably increase (but so what? If true, this would place greater importance on batters to prevent the count from reaching two strikes – that’s a good thing!)
I think this concept has promise to introduce all sorts of cool strategy, which I think fans would enjoy. Also, currently, most fans (including myself) essentially just want to see the outcome of the at-bat (there’s a little, but not much, interest in the pitch-by-pitch path that an at-bat takes to reach its outcome). I think the dynamic strike zone concept could add a significant amount of interest in the pitch-by-pitch path that an at-bat takes to reach its outcome (fans of the batter’s team licking their chops early in the at-bat, and fans of the pitcher’s team breathing a huge sigh of relief if he gets past that first perilous strike, to ultimately seeing fans of the pitcher’s team licking their chops late in the at-bat, and fans of the batter’s team crossing their fingers late in the at-bat – more so than they already do for a very tangible reason).
I’m not a huge fan of the ever-present strike zone graphic on TV (it’s okay I guess), but the dynamic strike zone concept could make it much cooler – fans watching at home can see the strike zone expand before their eyes as the at-bat progresses.
Overall, I think this concept could appeal to casual fans and purists alike.
- Other thoughts?
- Over the years, baseball’s harshest critics and biggest fans have rolled their eyes (and understandably so) about the uncertainty of the strike zone. If you ask X people on the street (even those knowledgeable about baseball) what the boundaries of the strike zone are, you’re likely to get X different answers. WHAT IF THE FUZZINESS SURROUNDING BASEBALL’S STRIKE ZONE BOUNDARIES – SEEN AS SILLY FOR SO LONG – ULTIMATELY TURNED OUT TO BE BASEBALL’S SALVATION? If strike zone boundaries instead were super-ingrained all along, it would make the dynamic strike zone concept a tougher sell. This longstanding fuzziness might help the concept gain acceptance.
- If the dynamic strike zone concept is possible at all (in other words, if capable technology exists), and if it’s effective at all, then MLB can take the concept to still higher levels of effectiveness in the years to follow, by tinkering as necessary with the three strike zones to produce the optimal effects
- Are batters crushing the ball like a video game with no strikes? Okay, let’s expand the 0-Strike Zone a little
- Are batters taking too many pitches with one strike already on them? Okay, let’s find a way to widen the disparity a little between the size of the 1-Strike Zone and the 2-Strike Zone
- Is the concept increasing hits and overall balls in play to a more palatable level, but with a few too many home runs? Okay, let’s keep the respective dynamic strike zones the same size, but let’s shift them all downward a few inches (or de-juice the baseball)
- There’s at least one other way to encourage batters to put the ball in play early in the at-bat (it has nothing to do with the strike zone), but it presents some pretty serious logistical concerns. Baseball could introduce a second pitching rubber (slightly farther from home plate than the current rubber), require pitchers to start every at-bat from the far rubber, and then allow pitchers to throw from the 60’6” rubber after getting one strike on the batter.
