There is an earthquake type shift in front offices. The glory days of "ace" starting pitchers are going to start to fade . . . fast. Just like the NFL has caused the running back position to become a generic commodity in its pass-happy offenses, baseball is soon going to put less emphasis on starting rotations to win games.
The trend has been accelerating this year. A report indicated that the amount of innings pitched by MLB starters is down 37 percent. It means that starters are pitching more than 2 innings less than they did a decade ago. It is apparent when you watch games. It is now a rarity for a starter to pitch into the 7th inning. A generation ago, starters all took the mound with the one goal of tossing a complete game. Today, starters are content with finishing just 5 innings.
Teams are constructing their bullpens not as emergency help for faltering starters but as a machine to win games. During Kansas City's World Series runs, it developed a killer bullpen of three dominant, "shut down" arms in the 7th, 8th and 9th innings. If the Royals were winning after 6, the game was over. The emphasis began to shift to the back three or four innings and not the front five.
Stats gurus have allegedly found that starting pitchers get hammered more when a batter sees them for the third time during a game. The logic is that the batter has now seen all the pitches of the starter so he can better anticipate what he will see. Also, the stat men found that the key innings in a game for a starter are the 2nd to 7th. Therefore, the Padres developed the concept of an "opener," a relief pitcher who would throw the first inning then give way to the starting pitcher. That means the starter will see the top of the opponent's order one less time during the game. This is how odd pitching metrics have gotten.
Closers used to be just mop up guys. Now, they are the highest paid bullpen pieces because for some mental reason, not every relief pitcher can get the last three outs in a game. Closers typically have one lights-out pitch; a 100 mph fastball, or a devastating fork ball. They are strike out pitchers. Teams now set up their bullpens just to get to the closer.
With starters only covering 5 innings, they are really no different than traditional "long" relievers who can spot start or throw 3 innings in a game. Long relievers are not paid as well as starters or closers. But in the new pitching playbook, they may become even more valuable.
Some teams without a decent fifth starter will result to having a "bullpen" day where long relievers will try to get 6 innings in the book before turning it over to the last three bullpen arms. In the near future, all teams may employ bullpen days for every game.
Teams are already carrying 12 or 13 pitchers on the 25 man roster. That is why so many teams, especially the Cubs, try to find bench players who can play multiple positions because they have very limited substitutes. The idea of expanding the roster to 26 players does not mean an extra bat will be added to help managers. Some teams are now employing the dual role of a pitcher/position player. The Reds have a relief pitcher who also can bat well and play the outfield. It is not usual for star pitchers to be the best player on their youth, high school or college teams. And it is not usual that they used to be the best hitter and fielder at multiple positions. But they lose part of the skill set when they just concentrate on pitching.
Even colleges are now concentrating on developing relief pitchers such as closers. In the past, Steve Stone remarked that all relief pitchers were "failed" starter. College World Series teams often have designated closers. Minor league systems now quickly separate prospects into starters and relievers as it is now just as important to find closers and long relievers.
Ownership has a vested stake in this new pitching philosophy. It should cost less payroll. the age of the $20-30 million starter will be over. Relief pitchers salaries have been going up recently, but closers usually top out around fifth starter money. If a team can save half of the starters annual salary, that is pure profit to the owners.
