going back to the discussion we had about 6 0r 7 pages back that touched on pitch counts and why i stated that Kershaw (in addition to his lack of control) gets pulled early..............

"Since 1968, I believe the intensity of every pitch has gotten harder and harder in the big leagues," said Orel Hershiser, the National League Cy Young Award winner in 1988. "In 1968, guys threw over the top, the ball went downhill and became a moving fastball. When they lowered the mound in 1969, they took away the pitcher's leverage. They took away the plane of the baseball, and a straight pitch became more on the plane of the bat. At that point, pitchers had to move the ball so it was not on the plane of the bat, and to do that, they had to increase the intensity on every pitch. Movement became a key, not just velocity. So with all the elements we have today, if the intensity of one pitch is increased by, say, 10 percent, then 125 pitches becomes 115, which becomes 110, then becomes 100.".......................
Hershiser made his major league debut in 1983. "I could rest at certain times during the game: two outs, no one on, seventh hitter up in the National League," he said. "I didn't want to show all my bullets at that time, so I'd throw a BP sinker away and get a ground out. If the guy got a hit, no big deal; you had the eighth and ninth hitters up. But you can't do that today with these lineups. You can't throw only 80 percent of what you have. You can't get by with a get-me-over curveball. What used to not be a big deal is now a huge deal.".........................................................
High-intensity pitches are often high-stress pitches. Teams all across the major leagues don't just count pitches; they count the number of pitches a pitcher makes under duress.
"The philosophy in our organization is, 'How did you get there?"' said Red Sox pitcher Josh Beckett. "When we have a 25-to-35-pitch inning, that's highly stressful for a pitcher. Our guys are very conscious of that. When you're in a highly stressful situation -- runner at second base, none out -- one pitch becomes a pitch and a half. We pay attention to that."
