If you were to design the ideal baseball player there are a lot of things you’d want that player to do. At the plate two of the things you would like that cyborg to be able to do is make tons of contact, and also hit for a bunch of power. That’s a very rare skillset for a player to have, historically. Players tend to balance a trade off of swinging hard enough to hit the ball with some authority. Finding players that have the ability to hit the ball with authority, but also have the bat control to make contact at a high rate is ideal.

With all of that said, I chose to take a look at the data for the Cincinnati Reds prospects in both their strikeout rate and their isolated power (SLG-AVG). There were no adjustments made for the isolated power numbers for the leagues played in. Try to make a note in your head, though, that the Florida State League where Daytona plays suppresses power quite a bit, and that the Pioneer League where Billings plays boosts power quite a bit. Also keep in mind that generally speaking, each level up the ladder sees more overall power. That’s usually because players mature physically, as well as mentally to what they can and can’t do damage on.

I chose to make a graph plotting out how every player with at least 150 plate appearances on the year performed in these two categories. For the Top 25 prospects at midseason I used their headshots to mark where they fall on the chart.

The lower and further to the right on the chart, the better. The higher up the chart, the higher the strikeout rate. The further to the right, the more power a player hit for. When looking at the chart, two players stand out. The first, is Ibandel Isabel. He was not a Top 25 midseason prospect, but given just how much his data point stood out, I chose to use his headshot on the chart. He’s so far ahead of everyone on the isolated power that it’s ridiculous. Toss in that he also spent the entire year in the Florida State League and it begins to get even more comical. With that said, his strikeout rate was also incredibly high.

The other player that stands out on the chart is Mariel Bautista. He got the nod over Isabel on the Position Player of the Year Award. He’s that lone head low and to the right. He did play in the hitter friendly Pioneer League, so you may want to mentally adjust the power a tad, but his contact rate was among the best in the entire organization, too. Below is the full list, sorted by isolated power. Top 25 Midseason Prospects are in bold (name only)

While the ideal player would be outstanding in both the contact and power category, it’s not too realistic for most players. The guys who can do both are among the best hitters alive (Jose Ramirez, Mookie Betts, Alex Bregman are the only three players with an IsoP over .250 and a strikeout rate under 15% this season). But being outstanding in one area or the other, can result in strong future results.

Having a high strikeout rate works for some hitters, but it’s almost always the guys with big time power. Among the top 60 hitters in Major League Baseball in terms of isolated power (.190 or better), only two of them are below-average hitters as measured by wRC+. Those two players are Jonathan Schoop and Salvador Perez – both who are among the lowest walk-rate players in baseball, and thus have very low on-base percentages.

When it comes to making contact at a high rate, things aren’t quite as telling. There are 31 qualified hitters in baseball with a strikeout rate under 15% this season. 12 of them are below-average hitters by wRC+, with 2 more sitting at 99 – which technically would make them below-average by definition, but wRC+ isn’t 100% perfect, so I’ll count a 99 as average. One of those players, for the record, is Reds shortstop Jose Peraza.

Power certainly seems to be more important to being an above-average hitter than contact rate does. Which makes sense. Power does more when it comes to producing runs. But that doesn’t mean contact is unimportant. It does mean it’s less important, though. With both things, there are limits. Simply getting the bat on the ball isn’t enough. You’ve got to do so with enough authority to get the ball into the outfield, and generally show enough pop to keep the outfielders honest or they’ll play in enough and take everything away from you that you float over the infield.

Likewise, you can show tons of isolated power, but if you can’t make enough contact to counteract a lower average/on-base percentage, it won’t matter enough, either. The balance between power and contact leans more on the power side of the scale. But being able to have both is usually something that is going to lead to very strong results.

    Really interesting. I wonder if their is a way to put a multiplier on it to make an effective stat. Kind of like how OPS combines slugging and on base. Maybe something along the lines of taking the power and a negative multiplier for the strikeout percentage?

      • Greenfield Red

        I was thinking of using something like a 25% strikeout rate as the norm. Subtract or add a .04 factor per strikeout rate below or above the 25%. That would make Isabel’s power/strikeout number .173. It would make Bautista’s .336. Trammell would have a .139. I guess it needs to be tweaked a little, but that’s the idea.

    Brian Rey’s strike out rate of 7%. Wow! Small sample size, in line with his amateur numbers, or I’m just showing my lack of baseball knowledge?

    This post explains why I am so excited about Debby Santana. He is young for US ball so I understood the adjustment period to playing and living in the USA. However in August his ISO was .260 and his K% was 14.10%. That is rare air.

    Contact is more important. Power is over-rated, because lots of power happens when it doesn’t matter. Strikeouts never help. Often, ground balls and fly balls do.

    • Doug Gray

      Nearly half of the Top 30 hitters in baseball ranked by contact rate are below-average hitters. 28 of 30 of the top hitters ranked by power are rated as above-average hitters.

      Try again. The evidence is overwhelming.

      • Jon Ryker

        But how do you rate them as above or below average? If you refuse to put context into your analysis and esteem power for its own sake, you will, of course, come up with power hitters as the most productive.

        But the fact is, many homers aren’t productive, strikeouts never are, and often fly outs and ground outs are.

        Actual production is situational.

      • Doug Gray

        It’s literally in the article, Jon.

        And the fact that you said many homers aren’t productive is insane. Literally every single home run produces at least one run. No other hit is directly as valuable as a home run.

      Don’t lots of strikeouts happen when it doesn’t matter either?

      I would think no scout would agree with this. HR are very important. You need a balance but even Joey Gallo has a WAR of 2.7 so far this year and 2.8 last year. That is with a whopping 35% K rate.

      • Jon Ryker

        WAR is not valuable. It is devoid of context and is based on runs-created, which is a bogus statistic.

        Strikeouts can come at unimportant times, but they are never productive.

        Actual winning happens in situational contexts.

    • Dave Bell

      Strikeouts can be helpful, if the alternative is hitting into a double play. Years ago, in one of his Baseball Abstracts, Bill James attempted to measure the value of a strikeout. I recall his making the DP point in his preface, pointing out that it was theoretically possible that, on average, a K could have a positive value. His study didn’t reveal that, if I recall. But I believe he concluded that every 100 strikeouts was only the equivalent of a loss of one run versus a normal distribution of other kinds of outs. They do have some predictive value, especially for players moving up the system and encountering increasingly skilled pitchers, and probably for aging Major Leaguers, for whom a spike in K rate often signals the beginning of the end. But the cost of a strikeout, in and of itself, is nominal.
