Pitchers aren’t bad hitters because they don’t practice, they’re bad hitters because they don’t have the ability.
For pitchers, the skill of pitching is so overwhelmingly important that how well they hit is of almost no relevance to their value; if a guy can pitch, you’re going to keep promoting him through the ranks of professional ball, even if he bats .050, but if he can’t pitch his career is over unless he can become a position player. Since hitting is not of any significancem players are not selected to be pitchers based in any way on their skill as hitters; from the time they’re in high school they’re being scouted and drafted based on pitching skill alone. So the guys you see in the majors have all gone through a process of natural selection in which hitting was not a selecting criteria. There’s no particular reason why major league pitchers SHOULD be able to hit, just as there is no particular reason why NFL quarterbacks should be able to kick field goals or NHL centers should make good NBA point guards. A pitcher’s skill set is 99% different from a hitter’s. He’s more or less playing a totally different sport, from a skill set point of view. Players who can do both, like Rick Ankiel or Mike Hampton, are extremely rare, and since Ankiel failed as a pitcher and Hampton isn’t a good hitter for a position player, there are not actually any active players who can pitch AND hit at the level of an average major leaguer.
It is interesting to note that although they work on it extensively and and natural skills needed are common to all athletic adult men, most pitchers are ALSO mediocre fielders, and some are brutally bad and yet have successful careers. Randy Johnson is notably inept; his career fielding percentage of .906 is probably worse than I’d do, but he’s the majors and I am not because his career ERA is 3.22 and mine would be 322.00. The reason guys ike Johnson aren’t losing their jobs for their fielding is because fielding doesn’t matter for a pitcher; pitchers just aren’t afforded the opportunity to make enough plays for it to matter. The absolute worst fielding pitcher in the majors, a guy like Johnson, probably doesn’t cost his team more than seven or eight outs or extra bases a year with his shitty fielding, (and I’m being liberal in my estimates.) Seven or eight outs in a season is a rounding error when comparing the performance of pitchers as pitchers.
Well, there you have it; as a hitter Gibson was good for a pitcher, but he was terrible by the standards of major league ballplayers. He did nothing well as a hitter; he was as bad a hitter as Mario Mendoza.
More practice would likely NOT have made Gibson a good hitter. Gibson was one of the greatest natural athletes of the 1960s, a master of multiple sports, and a ferocious competitor who took hitting very seriously and worked hard at it. He was hitting his whole life; he played lots and lots of baseball. And he was clearly outmatched as a hitter long before he got to the majors.
Hitting in baseball requires lots of practice but it also requires a lot of straightforward natural talent in terms of strength, muscle speed, and coordination, and if you don’t have it you never will.
That is not true. Of the top home run hitters of all time:
- Barry Bonds was known for his speed.
- Henry Aaron had above average speed.
- Babe Ruth was very slow in the latter half of his career, but good speed in the first half.
- Willie Mays was extremely fast.
- Sammy Sosa ran very well for most of his career.
- Ken Griffey Jr. has run pretty well, slowing down a bit in the 30s.
- Frank Robinson ran well.
- Mark McGwire was very slow.
- Harmon Killebrew was very slow.
- Rafael Palmiero was slow, but not like Killebrew.
- Reggie Jackson ran well for most of his career, was quite fast when he was with Oakland.
- Mike Schmidt ran pretty well.
- Mickey Mantle was extremely fast,
- Jimmie Foxx had average speed.
- (Tie) Willie McCovey was elegant, but slow due to injury. Ted Williams was slow because he was just a poor runner.
So of the top 16 guys, there’s really only two slow-as-molasses players (McGwire and Killebrew) and one who was slow as molasses half his career (Ruth.) Some were a bit slow, but most ran well or very well and some were VERY fast, like Mays, Mantle, and Bonds.
