My Starting Pitcher Ranking system (SPR) was developed to better measure a starting pitcher's ability to efficiently
prevent runs. It includes metrics in 7 different categories:  Command
 Stuff
 Batted Ball
Tendency
 Durability
 Versatility
 Consistency
 Quality of the Opposition
It
begins with "outcome" measuresthe end result of the batterpitcher matchupthat the pitcher controls: Krate,
BBrate and HRrate...the components of Fielding Independent Pitching (FIP). It also includes "process" measuresthings
over which the pitcher has some control that happen during the plate appearance: his swing & miss rate, the frequency
with which he throws strikes, and his fastball velocity. The groundball/flyball rate is another important component, since
flyballs yield runs at 2.5x the rate of groundballs. A pitcher also gets credit for durabilitypitching deep into games and
not missing starts. The essence of a starting pitcher vs. a reliever is his ability to pitch
effectively to both righthanded and lefthanded batters. A starting pitcher's platoon splits are factored into the SPR, as
is his consistency, as measured by the gametogame variation in his performance. Finally, the quality of the oppposition
a pitcher faces is accounted for in the SPR. The combination of the unbalanced schedule, coupled with the reality of pitching
every 5th day, leads to significant swings in the quality of a pitcher's opponent. The primary differences between the SPR
and other measures are:  It explicitly values groundballs over flyballs
 It values pitching deep into
games, based on its affect on a team's bullpen usage
 It gives starting pitchers credit for narrow platoon splits
 It
rewards gametogame consistency
 It adjusts for the quality of the opposition
Valuing
Groundballs vs. Flyballs While batting average on groundballs is slightly higher (.234)
than average on flyballs (.219), slugging percentage on flyballs is significantly higher (.580 vs. .253 for groundballs).
As a result, flyballs generate runs at a rate 2.5 times greater than groundballs. If Tim Hudson (an extreme groundball pitcher)
and Kevin Slowey (extreme flyball pitcher), pitched equally effectively with the only difference being their batted ball tendencies,
Slowey would yield 12% more runs and have a .030 higher OPS against, over the course of a season. Pitching Deep into Games In a recent study, I quantified the value of pitching
deep into games, by analyzing the quality of relievers that typically pitch each relief inningfrom innings 5 thru 9. The
difference between starters who are "horses" and go deep into games vs. those who don't is the frequency of relievers
covering portions of the 5th, 6th and 7th innings. Based on the quality of middle inning relievers, the difference between
Roy Halladay, who averaged 7.3 IP per game (2011) and an equally effective pitcher who pitches a MLB average 6.0 IP per game
is 12 runs over 33 starts. In other words, in Halladay's starts, he saves his team 12 runs vs. an equally effective pitcher
who pitches 43 less innings over the course of a full season. Quality of Opposition
Adjustment The array of teams a starting pitcher faces often gets overlooked when judging his performance.
In 2011, CJ Wilson started 34 games. Fourteen of his starts were against teams in MLB's lowest quartile offenses (as measured
by OPS). Conversely, Toronto's Ricky Romero had one of the toughest schedules of any starting pitcher, facing 1st and 2nd
quartile opponents in nearly 70% of his starts. The SPR includes an adjustment to each starting pitcher's stats to reflect
the quality of the opponents they faced. Follow me on twitter...@vincegennaro


Starting Pitcher Rankings2011 The 2011 final rankings are
listed below. The rating score is scaled so that 100+ is an "elite" season by a pitcher. Roy Halladay is the only
pitcher to have a score of over 100 for each of the last 4 seasons. SCORE   RANK  PITCHER  107   1  HALLADAY,
