There's been an evident trend in Major League Baseball dating back decades now of starting pitchers throwing less and less pitches per start and as a result less innings over a full season. Managers and front office analysts want to avoid having their starting pitchers face opposing lineups a third time thru the order while also leveraging more and more talented relief specialists who light up the radar gun.
Aaron and I were having a conversation about this topic as it relates to the BBA under a recent Jacksonville TN post and I decided to pull the data to back up one of my hunches--that we're seeing a decline in the number of established, top tier starting pitchers logging over 200 innings. Below is a count of starting pitchers who met the 200 inning, 175 inning, and 150 inning threshold for every season since I joined the league.
> 200 IP | > 175 IP | > 150 IP | |
---|---|---|---|
2051 | 31 | 66 | 114 |
2052 | 38 | 82 | 125 |
2053 | 40 | 92 | 132 |
2054 | 46 | 97 | 138 |
2055 | 41 | 85 | 128 |
2056 | 40 | 87 | 122 |
2057 | 28 | 74 | 121 |
2058 | 38 | 75 | 124 |
2059 | 32 | 88 | 130 |
2060 | 36 | 98 | 138 |
2061 | 30 | 81 | 119 |
2062 | 10 | 70 | 112 |
I pulled the data in chronological order so to be honest I was pretty disappointed to not really see a trend over the years until suddenly I reached 2062. After averaging 36 pitchers who tossed 200 or more innings from 2051 to 2061 that number nosedived to just 10 pitchers in 2062.
Below is the list of those 10 pitchers.
Name | AGE | Team | IP | ERA |
---|---|---|---|---|
Shinsui Hasegawa | 32 | CLG | 238.2 | 3.55 |
Brian Whitford | 25 | ATC | 223.2 | 2.90 |
Dave Corfield | 37 | MEX | 219 | 3.78 |
Garth Dobbs | 28 | DM | 215.1 | 2.88 |
George White | 24 | SA | 213.1 | 4.56 |
Hector Silva | 30 | CCJ | 211 | 3.80 |
Ji-e Woo | 34 | MEX | 210.1 | 4.19 |
John O'Leary | 23 | POR | 205 | 4.04 |
Cesar Franco | 25 | SA | 202.1 | 4.45 |
Buwono Mainaky | 33 | CHA | 202.1 | 3.07 |
As I mentioned in the intro, there can be several reasons for this phenomenon. Is it front office strategy to limit how many times opposing hitters see your starters? Is it a fallow period for starting pitching talent? Or--as in the case of my pet theory--is it a reaction to the increased talent level of the relief pitchers entering the league? I can't say for certain, but you should take note that if you didn't have a 200 inning pitcher on your staff this season you were in the majority of teams.
