"85 wins would not be unrealistic." Carlos Tosca

Welcome to my 7th-annual "Blue Jays Projected Record" article in which I sum individual projections for the Blue Jays players to project a win-loss record for the Blue Jays *before* the season starts. (See disclaimer below on accuracy.)


2003 Offense

For each player, I projected his Equivalent Average (EqA). For those new to EqA, an average major league hitter has an EqA of .260, and an EqA of .300 represents excellence. Because of the DH rule, the average American League hitter has about a .264 EqA. EqA is directly related to how much the player helps the team score runs.

For projected EqA, in most cases I used a formula (same as last year) that incorporates past major league performance, past minor league performance (when major league data seemed insufficient) and the player's age.

For projected plate appearances (PA), I picked a number in line with the player's playing time history but also considered how the Jays intend to use the player this year.

Here are the individual hitting projections:

    
                 Age ProjEqA  
     Stewart LF   29  .280    640 PA
 Catalanotto RF   29  .277    450 PA
      VWells CF   24  .263    630 PA
     Delgado 1B   31  .312    620 PA
      Phelps DH   25  .290    600 PA
     EHinske 3B   25  .293    650 PA
     OHudson 2B   25  .258    500 PA
    Woodward SS   27  .266    400 PA
     Huckaby C    32  .200    250 PA
                      ----   ----
                      .277   4740 PA

                 Age ProjEqA  
     Bordick IF   37  .237    300 PA
        Berg UT   32  .243    250 PA
     TWilson C    32  .248    200 PA
      GMyers C    37  .246    150 PA
       Werth OF   24  .250    250 PA
       KCash C    25  .240    150 PA
      HClark IF   29  .240     50 PA
       DWise OF   25  .230     35 PA
    RJohnson OF   26  .220     20 PA
    Pitchers          .100     20 PA
                      ----   ----
                      .241   1425 PA

The team offense projects to a .269 EqA. Remembering the 4% adjustment for the DH league, this works out to an offense 5% better than league average:

  (.269/.260)^2.5 / 1.04 = 1.05 (5% above league average)

For example, if you figure an average team will score 5 runs per game, then the Jays would project to score 5*1.05 per game (5.25).

This performance would only be a modest improvement on last year's offense which was about 2% better than average (depending on the park factor estimate). While younger players are expected to improve, I don't project "breakout" seasons. If the Jays have one or more of those, the offense could be a lot better. On the other hand, if the Jays have to use the bench a lot, the offense would suffer (except at the catching position).


2003 Pitching

For projected opponents EqA, while I looked at formula estimates based on the pitchers' runs allowed history and "defense-independent" history (as per McCracken theory) including recent minor league history if major league data seemed insufficient, and while the pitcher's age was also considered, a lot of subjective reasoning went into the final guess. In particular, a lot of the pitchers don't have a lot of major league history, and some of those are over-age minor leaguers (e.g. ALopez, TMiller, DLinton). It's not well studied how to translate over-age minor league stats; I tended to assume they would not be much better than "replacement level".

For projected innings pitched (IP) and games started (GS), I picked numbers in line with what the pitcher had done in the past (adjusted somewhat based on the Jays' expected use of the player).

In principle, one should adjust for team fielding if its quality is expected to be different than most of the pitchers are used to. I don't expect a big quality difference from last year. The Jays might not be as strong in right-field, but the infield defense seems likely to be better.

For those not used to opponents EqA as a pitching stat, remember that .260 is average (like having a 4.50 ERA, or a .500 pitcher). Halladay's runs allowed average last year translated to .226 opponents EqA. "Replacement level" (what the better triple-A pitchers can probably do) would be about .275.

Here are the individual pitching projections:

Starters:
             Age         OppEqA
     Halladay 26, 215 IP, .230, 32 GS
        Lidle 31, 180 IP, .255, 30 GS
 MHendrickson 29, 130 IP, .265, 20 GS
      Sturtze 32, 170 IP, .275, 30 GS
      JMiller 25, 140 IP, .270, 23 GS
      PWalker 34, 120 IP, .270, 20 GS
      JArnold 24,  35 IP, .265,  7 GS
                  ---
                  990 IP  .259
Pen:
             Age         OppEqA
     KEscobar 27,  80 IP, .250
     CPolitte 29,  75 IP, .240
       DCreek 34,  50 IP, .280
         JTam 32,  60 IP, .260
       ALopez 28,  70 IP, .270
      TMiller 30,  60 IP, .270
      DLinton 38,  20 IP, .275
       Bowles 26,  20 IP, .265
     CThurman 24,  10 IP, .270
       MSmith 25,   8 IP, .275
                  ---
                  453 IP  .261

Overall that works out to a projected .260 opponents EqA for the staff, or league average. That would be an improvement on last year (which was about 4% worse than average). The Jays focused on improving their pitching in the off-season, though only one of the new pitchers is projected to be better than average (Cory Lidle). While the above assumes another strong season from Roy Halladay, he wouldn't have to pitch as well or as much as last year to exceed the above projection.


2003 Projected Record

To estimate the projected team winning percentage, we use the Pythagorean formula with an exponent of 1.83:

 1.05^1.83 / (1.05^1.83 + 1.00^1.83) = 0.522 wpct
 -->85 wins, 77 losses

So that's my official projection this year: 85 wins.

85 wins would be 7 more wins than last year's team achieved and 5 more wins than last year's Pythagorean record. However, it's 9 fewer wins than you would project from last year's post-All Star Break record (44-32, .579) because the evidence of earlier performance was not ignored.

85 wins is also the number Carlos Tosca said "would not be unrealistic" for this year's team. It would be 4 fewer than the Jays won in Bobby Cox's second year (1983). (In Cox's first year, the Jays won 78, the same as the 2002 Jays.)

But another third-place finish out-of-the-playoffs is not inevitable. For instance, the 2003 Jays have similarities to the 2000 White Sox. In 1999, the young White Sox won just 75 games with poor pitching. In 2000, their hitters improved a lot, their pitching became a little better than average, and they won 95 games (most in the league). Last year, the Jays played at a 94-win pace after the All-Star Break.


Disclaimer

Toss a fair coin 162 times, and your best bet is to predict 81 heads, but there's only a 6% of chance of that happening, even though it really is the best bet. There's a 5% chance that the fair coin will produce either 68 heads or fewer or 94 heads or more.

Even if this article has accurately estimated the Jays' probability of winning each game, there's just a 6% chance of the projected win total matching the actual. The 95% confidence interval for an "85-win coin" is approximately 73 to 97 wins.

(But we're not claiming to even be 95% sure of a 73 to 97 win season, because we can't be sure the errors in the individual projections will all cancel out, and we can't be sure that all the other assumptions of this article are valid.)

If we do assume an 85-win quality team, the Jays have a 24% chance of winning 90 games or more and a 7% chance of winning 95 or more (based on assuming a probability of 85/162 of winning each game).
