Appreciating the historic, unhittable greatness of Billy Wagner

25 Comments

Billy Wagner’s phenomenal career ending with him leaving a save situation and limping off the field before being replaced on the playoff roster due to an oblique injury is all kinds of not fair, but the diminutive flame-thrower remained a badass until the very end, agreeing to a pair of injections for the slim chance it would allow him to pitch again because he “didn’t care about the risk of long-term injury.”
My hope is that the unfortunate manner his career ended doesn’t take anything away from how spectacular he was for 15 seasons. Wagner is a seven-time All-Star who ranks fifth all time with 422 saves, but a deeper look at his career numbers reveals his true dominance.
For instance, among all the pitchers in baseball history with at least 800 career innings Wagner has the highest strikeout rate:

                     SO/9
BILLY WAGNER        11.92
Randy Johnson       10.61
Kerry Wood          10.35
Pedro Martinez      10.04
Nolan Ryan           9.55

That’s a pretty amazing list to sit atop. Not coincidentally, he’s also the all-time leader in fewest hits allowed per nine innings:

                     H/9
BILLY WAGNER        5.99
Herb Score          6.39
Nolan Ryan          6.56
Sandy Koufax        6.79
J.R. Richard        6.88

Wagner is also the all-time leader in adjusted ERA+ among all left-handed relievers with at least 800 innings:

                      ERA+
BILLY WAGNER          187
John Franco           138
John Hiller           134
Sparky Lyle           128
Jesse Orosco          126

The degree to which Wagner blows away the rest of the lefty reliever competition in ERA+ is ridiculous. To put those numbers in some context, consider that the difference between Wagner at 187 and second-place John Franco at 138 is bigger than the difference between Franco at 138 and, say, Scott Schoeneweis at 92.
And here’s how Wagner ranks in ERA+ among all relievers with 800-plus career innings:

                      ERA+
Mariano Rivera        204
BILLY WAGNER          187
Hoyt Wilhelm          147
Dan Quisenberry       147
Trevor Hoffman        141

Highest strikeout rate of all time, fewest hits per nine innings of all time, best ERA+ ever by a left-handed reliever, and second-best ERA+ among all relievers behind only Mariano Rivera. I really hope everyone who saw Wagner limp off the mound Friday night realizes they saw the end of one of the most extraordinarily dominant reliever careers in baseball history.
In his final season, at age 38, he saved 37 games with a 1.43 ERA, .159 opponents’ batting average, and 13.5 strikeouts per nine innings. I hope Wagner enjoys his retirement, because I know National League hitters will.

Zac Rosscup throws immaculate inning, lands on DL

A day after throwing an immaculate inning — getting through an inning on three consecutive strikeouts with nine pitches — against the Mariners, Dodgers reliever Zac Rosscup was placed on the 10-day disabled list with a left calf strain. The move made room on the 25-man roster for Kenley Jansen, who is back after missing some time due to an irregular heartbeat.

Rosscup pitched the ninth inning of Sunday’s 12-1 win over the Mariners. He struck out Kyle Seager, Ryon Healy, and Cameron Maybin on three pitches each. Rosscup is the fourth pitcher to throw an immaculate inning this season, joining Kevin Gausman, Max Scherzer, and German Marquez. 2018’s four immaculate innings is still far behind 2017’s record of eight.

Rosscup has pitched only 6 2/3 innings in the majors this year. He has yielded five runs (all earned) on seven hits and a walk with 10 strikeouts. He missed a significant amount of time earlier this season due to a blister on his left middle finger.
