Digital Baseball Umpires

Dekaner writes "Wired is running an article on an electronic umpire that tracks each baseball pitch and judges whether it is within the "strike zone" has been installed at 10 major league ballparks in the U.S. The QuesTec system uses several cameras that track each pitch and compare the machine's judgment with that of the umpire standing behind the catcher. At the end of each game it provides a summary of its ratings and compares them with the umpire's calls. In general there is reasonably good agreement. In a recent test the QuesTec system judged that 32.1 percent of pitches were within the "strike zone", while the umpire called 31.4 percent as strikes. However, the umpires association has filed a complaint about the system's unreliability and incapability to replace the human 3-D, real-time view. "

    The ICC adopted a similar scheme some time ago, but it was to assist the umpires rather than replace them.

    Jesus Christ. I thought you were lying about the salary issue, so I looked it up:

    "NEW YORK (9/5/00) _ Umpires will get raises of 10.2 percent to 14.9 percent this year under their new five-year contract, boosting the minimum salary this season to $104,704 and the maximum to $324,545. In 2004, the contract's final season, the minimum will be $108,716, up 14.4 percent from the $95,000 minimum in 1999, the final year of the old contract."

    I don't see how this could cost a single umpire their job - remember, you still have to have an ump at each base for safe vs. out calls, checked swing rulings, balks, time outs, etc.

    Gee, 100K to 300K a year umps. Of course everyone else out there on the field is making 3 million to 300 million or more.
    Hard to feel like the umps are being overpaid.

    So why not robotic players? Lets get people totally out of the game.

  5. One problem... by siskbc · · Score: 4, Informative
    ...is that it's not uniform, being installed in 13 (as opposed to the 10 that Taco quotes) of the 31 MLB stadiums (counting Hiram Bithorn in Puerto Rico). Umpires have admitted calling games different (ie, correctly) when they're in a stadium that has Questec.

    I recall that one catcher was supposedly told by an umpire that he wanted to call a lot of those pitches strikes, but he couldn't. Catcher seemed to think this was a bad thing. So, in other words, the umpire admits that he doesn't typically enforce the rules as written unless outright forced to? Sounds like he's completely justifying the existence of the machines to me. Maybe now Atlanta pitchers won't get their customary strike zone that stretches between the home and visiting dugouts?

  6. Taxpayer involvement by ArsSineArtificio · · Score: 2, Informative

    Dude, it's not like it's taxpayer money.

    Given that taxpayers typically paid for the useless-almost-every-day-of-the-year giant ballpark in which umpires "work", it's not too much of a stretch to imagine that ridiculously high umpire salaries are made possible by the fact that other parts of the baseball enterprise are financed by taxpayer money.

  7. I'm not sure you understand the complaint by belloc · · Score: 5, Informative

    The main problem that the umps have is not that it might replace them, but that it might not really be more accurate than them. This quote is from the article (which is the little clicky linky thing that you often find in the story text...we should all try clicking it sometime!):

    "Even if (the computer operators) were experienced umpires, this system would not work because it's based on a single frontal photograph in comparison with the 3-D, real-time view of the umpire," Gibson said.

    In addition, many batters move during the course of the pitch, which an umpire sees and weighs in determining the strike zone, he said.


    See, each time a batter steps to the plate, the system has to be calibrated for that batter's particular size, crouch, stance angle, etc. But that calibration is only done once (at the beginning of the at bat), and it's done by...a human being, just like the umpires. And often, this operator, while he may know the system, doesn't understand the game of baseball.

    So the umpires' beef is not that they don't want to be evaluated, it's just a question of whether the measuring stick is really doing a better job than they can do standing right behind the plate.

    While I think Joe Morgan was one of the greatest 2B of all time he is woefully behind the times when it comes to baseball analysis.
    He still does not understand the value of OBP for leadoff hitters, does not believe in pitch counts and thinks everyone tht played with him on the Big Red Machine is a Hall of Famer (slight exageration but not that far from the truth).
    He is quite "old school" and would be naturally distrusting of any new technology in the game. I would hesitate to use Mogan as a source of unbiased analysis on this subject.

    I think you've been reading the sports headlines too much. The average baseball player makes about $200,000 a year... The avg. career length is about 2-3 years.


    The New York Yankees this season have a combined salary of $130 million. The league average among the 30 teams is about $70 million. There are 25 active players on each team's roster, plus 15 more than can be listed as on the official 40-man roster that is used to determine post-season eligibility.


    Must be the new math, but your average appears to be off by a factor of 10. The average MLB player makes about $2 million.


    Also, considering that the league minimum salary (as of the last collective bargaining agreement) is $250,000.... I'd say your average is completely bogus.

    I sense sarcasm, but I feel I should give the facts anyway. For a regular season major league baseball game there are four umpires (one for each base), compared to the nine defensive players that are always on the field, plus the batter and as many as three runners on base. So there are four umpires for as many as 13 players on the field. This is about the same ratio as the NBA (3 refs for 10 players) and the NFL (7 officials for 22 players).

    For the playoffs, major league baseball adds 2 umpires, one down each foul line so the outfield is covered better. In the minor leagues, there are usually only 3 umpires per game during the regular season.
