Is Using Wins + Quality Starts the Answer?
Rotograph’s venerable duo Mike Podhorzer and David Wiers recently contemplated aloud a new statistic, formulated by Ron Shandler, that replaces Wins (W) and Quality Starts (QS) by simply adding the two (W+QS). Chandler decided to use this approach in monthly fantasy leagues, and its useful to look at how using this combination could best be used to solve an implacable problem, the overall crappiness of using wins to evaluate a pitcher’s ability.
W+QS is interesting because it weights QS more than W, since a pitcher usually has considerably more QS than W. With a mean of 19 QS and only 12 W, a starting pitcher is more likely to throw at least six innings with 3 earned runs or less than he is to get the W. Wins are capricious and depend greatly on the pitcher’s offensive support. As a way to measure a pitcher’s ability, one might argue that wins are a waste of time. In fantasy baseball, a pitcher is most often valued by his ERA, WHIP, number of Ks and W and Saves. Some more progressive leagues use QS in place of the W.
As evidenced by the table below, ranking a pitcher by W+QS instead of wins alone certainly helps many a fine pitcher, especially James Shields, who leads the league in QS but only is ranked 38th in wins, while also penalizing others like Shelby Miller who has even more wins (14) than quality starts (12). Stephen Strasburg and Cole Hamels see the greatest percent increase jumping from wins to QS+W, while Jeremy Hellickson and Shelby Miller’s total changed the least.
Conversely, Shelby Miller and Jeff Locke saw the greatest increase from quality starts to W+QS, again showing that Mr. Miller, while pitching well his first full season, got the W more often that he made a quality start. A quick glance at his game log shows the innings-limited young pitcher often earned the win when pitching less than the 6 innings needed to record a quality start.

In fantasy, the 5 categories are meant to evaluate the overall value of a pitcher, and players that are best able to predict future value can win serious jelly beans. A pitcher accumulates Ks by defeating individual batters, while a low WHIP indicates that he can avoid putting opposing players on base. ERA evaluates a pitcher’s run prevention skill. Saves and wins are meant to measure a pitcher’s ability to dominate opposing teams, whether for an inning or an entire game. However, wins compare poorly with quality starts and W+QS when correlated with commonly used pitching statistics.
The chart below shows the correlation between wins, quality starts, and the combination of the two with other commonly used pitcher evaluation metrics. By calculating the correlation between these 3 categories and other pitcher metrics such as FIP, OPS allowed, batting average against, homeruns allowed per 9 innings, and runs above average by the 24 base/out states (RE24), we can measure not only the relationship between the variables, but also how much they differ from each other.
None of these statistics correlate as well with wins as they do with quality starts and W+QS. In fact, the difference between QS and W+QS is negligible in every case. This result makes sense—since QS make up the majority of the W+QS total, the two are almost identical in the chart. The actual values of each correlation are less important that the overwhelming conclusion that wins do not have much to do with pitcher skill, while the difference between QS and W+QS is negligible.
Why, then, might it be useful to use W+QS? These results show that it may not be very different from using quality starts, but is far more reliable way to judge a pitcher’s performance than wins alone. W+QS double count the games when a pitcher goes somewhat deep into a game, pitches fairly well (3 ER or less), and exits the game while leading his opponent. This scenario might not be much different than the QS by itself, but it does retain an element of “winning the ballgame for your team”, which is what the win category somewhat accurately captures. A winning pitcher is generally on a winning team, although that statement may not mean much.
W+QS may be an unnecessarily complicated way to repeat the same evaluation standards as quality starts, but some players may prefer it simply because it retains the W while relegating it to a position of less importance. Maybe owning a great pitcher like James Shields doesn’t have to be so frustrating after all.
