Mariano Rivera strikeout rate, walks, and ERA holding up
This article gives some perspective to Rivera's current stats like K's, BB's, ERA, velocity, and pitch values:
8/18/11, "Any worries about Mariano Rivera should be quickly dismissed," FantasyWindup, USA Today blogs, by FantasyPros911, P. DiCaprio
"After a few dicey performances many fantasy owners are asking whether Mariano Rivera is nearing the end of his illustrious career. If he is, there is no evidence of it, as we will see below. If anything, his skill set shows little or no erosion.
Strikeouts - His strikeout rate is up to 8.04 K/9, well above last year's mediocre 6.75 showing. The 2011 figure is down from his peak, but well within his expected range of strikeout rates. Rivera has struck out fewer batters per nine in nine of his 17 seasons.
Walks - His walk rate has gotten even better as he has aged. He has walked fewer than two batters per nine innings in each of the last six seasons, twice walking fewer than one batter per nine. The two seasons? 2008 and 2011, when Rivera walked 0.76 and 0.96 batters per nine. So, 2011 represents his second best control season.
ERA - His current ERA is 2.30, plenty good for anyone. But is it a product of his skill, luck or something else? One way to tell is to look at the more advanced metrics. So let's look at FIP and xFIP (both from Fangraphs.com) and xERA (from BaseballHQ.com) -- three of the more useful ERA estimators:
Actual ERA: 2.30
FIP (Fielding Independent Pitching): 2.38
xFIP (Expected FIP): 2.70
xERA (Expected ERA): 2.84
These metrics purport to distill a pitcher's ERA into its component parts to see if his ERA is likely to regress to a mean. Here Rivera's ERA is clearly not subject to anything other than a tiny regression.
Pitch Values - Fangraphs.com tracks pitcher velocity and determines a run value for each pitch type. Mariano's 92.1 average fastball velocity is almost exactly the same as in 2010 (92.2). But we all know his fastball is not his bread and butter. In fact he has thrown it only 11% of the time, by far a career low, aside from 2009, and part of a continued reliance on the cutter as he has aged.
As it turns out he has lost a step on his cutter in terms of run value. Mariano has seen a three-year decline in his cutter run value: 25.2 in 2008, 19.8 in 2009, 16.7 in 2010 and 8.0 so far this year. With roughly a quarter of the season left, we can prorate 2011 to 10.0 by the end of the season. This looks like a big decline, and it is.
- But it only tells half the story.
The decline is from his career high. Prior to 2008 his cutter run value was 12.2 in 2006 and 11.5 in 2007, seasons in which he had fewer strikeouts, but relied on his fastball much more often.
Of course we expect some decline in a 41-year-old pitcher. But Mariano is still rock solid for fantasy players. And if you do not agree, how many closers would you take ahead of him?

'Mariano Rivera best relief pitcher in history,' even in regular season alone, Corcoran, SI.com
This SI article written shortly after Trevor Hoffman's retirement says Mariano is the greatest relief pitcher in history which is nice but it only looks at regular season. The article also discusses Hall of Fame worthiness. For its purposes, Rivera did all his post season and All Star work for nothing and the Hall of Fame is now a glorified Cy Young Award.
- 1/12/2011, "Where Hoffman ranks among baseball's best closers ever," SI.com, C. Corcoran
"Trevor Hoffman retired on Tuesday with 601 saves, the most in baseball history, which alone puts him in the discussion for being the greatest relief pitcher in baseball history. Unfortunately for Hoffman, it's a short conversation. By virtually every measure, that title belongs to Mariano Rivera. In some ways, Hoffman benefitted from comparisons to Rivera, his almost exact contemporary, as he was widely regarded as the National League's answer to the Yankees icon. However, now that Hoffman has retired, that league distinction
- is largely irrelevant and
- the comparison becomes unflattering.
Yes, Hoffman matched Rivera's ability to convert saves (they both did so at an 89 percent rate over the length of their careers, a better rate than any other closer with 300 or more career saves) and Hoffman had more 20-save seasons than any other pitcher with 15 to Rivera's 14, but the
- statistical similarities all but end right there.
Rivera has converted more than twice as many saves of more than three outs (115 to Hoffman's 55), and crushes Hoffman in park-adjusted career ERA+ 204 to 141 (with 100 being league average). Having just signed a new two-year contract, Rivera should match Hoffman with a 15th 20-save campaign this season and seems likely to pick up the 43 saves he needs to break Hoffman's career saves record no later than 2012.
Rivera also has a big lead among relievers in most big-picture advanced stats including both versions of Wins Above Replacement (WAR, hereafter referred to as bWAR for Baseball-Reference's version and fWAR for FanGraph's), Baseball Prospectus's Wins Above Replacement Player (WARP), and BP's WXRL (roughly Wins eXpected above Replacement, adjusted for Leverage, a cumulative win-expectancy-based statistic for relief pitchers). Given all of that, the more pertinent question is whether or not Hoffman was the second-best relief pitcher in baseball history, and if not, where does he rank on that list?
Scanning those advanced stats as a group, five names continue to pop up towards the top of those lists behind Rivera: Hall of Famers Hoyt Wilhelm and Goose Gossage, Lee Smith, the man whose career saves record Hoffman broke in 2006, and Hoffman and Billy Wagner, both of whom have just retired this offseason. Noteworthy absences from that quintet are three of the five relief pitchers already in the Hall of Fame, Dennis Eckersley, Bruce Sutter and Rollie Fingers. Eckersley quite simply didn't spend enough of his career as a premium reliever to merit mention. Though he was dominant for five seasons (1988-1992), he posted a 4.05 ERA over the next five before fading away. He ranks 20th all-time in WXRL, and his bWAR for the relief portion of his career ranks down around 45th among relief pitchers, tied with the likes of Gene Garber and Greg Minton. Sutter similarly had just seven seasons with more than 20 saves and an ERA below 4.00. He ranks 14th in WXRL and ninth in bWAR. Fingers saved 341 games, which stood as the career saves record for all but one year between Wilhelm and Smith, and still holds the record for saves of more than three outs with 201 (Sutter ranks third in that category), but he ranks sixth on the WXRL list, just barely ahead of Wilhelm, and fails to crack the top five in any of the wins above replacement stats.
Getting back to our Big Six of Rivera, Wilhelm, Gossage, Smith, Hoffman, and Wagner, we've already established Rivera as the best reliever in baseball history. As for the rest, we'll start with how Hoffman stacks up against Wagner, his other contemporary. Though Wagner has a decided advantage in ERA+ and was one of the great strikeout pitchers in the game's history -- his career rate of 11.9 strikeouts per nine inning ranks behind only Brad Lidge's 12.0 among pitchers with 500 innings pitched (Hoffman's 9.36 K/9 ranks 28th) -- Hoffman holds the edge in save percentage (89 to 86) and saves of more than three outs (55 to 36). He also ranks ahead of Wagner in three of those four advanced stats, trailing him only in fWAR, which produces the leader board least like the other three because it's limited to the period since 1980. It's safe to say, then, that Hoffman was the second-best relief pitcher of his era, behind Rivera but ahead of Wagner. Hoffman also holds a clear edge over Smith, as well, with Smith's only meaningful advantage coming in saves of more than three outs, which, again, had more to do with when he pitched than how he pitched.
Comparing Hoffman to Gossage and Wilhelm, however, is more difficult because of the manner in which each of those pitchers was used. During his nine-year peak, Gossage averaged 93 innings per season. Take out 1979, which he missed most of because of a thumb injury, and the strike-shortened 1981 and his average jumps up to 104 innings in his seven full seasons during that stretch. Gossage also threw 141 2/3 innings of pure relief in 1975, his first full season as a bullpen stopper. Wilhelm, meanwhile, pitched most of his career before the saves statistic was invented in 1969 and surpassed 100 innings of relief work eight times in his first 14 seasons.
- By comparison, Hoffman averaged less than 63 innings pitched in his 15 20-save seasons.
Hoffman's comparatively light workloads play a large part in his his less-than-convincing showings in the wins above replacement stats, all of which are cumulative, and none of which rank him higher than fourth among relief pitchers. Hoffman, who never made a major league start, threw just 1,089 1/3 innings in his career, 30 percent fewer than the amount of relief innings thrown by Gossage, and just 58 percent as many relief innings as Wilhelm. However, WXRL, which is also cumulative but is weighted by the importance of the game situation, does rank Hoffman second (albeit distantly) to Rivera but ahead of the third-place Gossage while bumping Wilhelm all the way down to seventh. Similarly, Hoffman's poor showing on the list of
- career saves of more than three outs (he's 72nd)
has more to do with the usage patterns for closers during his career than anything else. In the 18 seasons since his rookie year of 1993, Hoffman ranks second to only Rivera in saves of more than three outs.
As a result, where you rank Hoffman relative to Wilhelm and Gossage really depends on whether you prefer a lock-down, three-out closer, or an
- old-school multi-inning fireman with somewhat less consistent results.*
- [See ed. note about Gossage in high stakes games at end of this post ].
It's hard to ignore the fact that Wilhelm threw nearly twice as many innings of relief while also posting a superior ERA+ (Hoffman ranks 12th in ERA+ among relievers with 500 or more innings pitched, below current Reds closer Francisco Cordero and former Blue Jays and Angels set-up man Mark Eichhorn) and converting far more than twice as many saves of more than three outs. Gossage ranks second all-time in the latter category and is second to Rivera in bWAR among relievers
- if you eliminate the seasons Wilhelm and Gossage spent as starters (1959 for Wilhelm, 1976 for Gossage).
Wilhelm, meanwhile, leads in WARP among relievers. Hoffman leads the trio in saves, save percentage, fWAR, WXRL, K/9, K/BB, and WHIP, but, again, with just 58 percent as many relief innings pitched as Wilhelm and 30 percent fewer than Gossage.
Each of the three had a dominant run of nine consecutive seasons. If we narrow our focus to those seasons alone, we get the following:

A popular but especially erroneous stat about Rivera durability in 2010
"Understanding that you can make any point you like with statistics..." Wallace Matthews, ESPN NY, 11/4/2010 (para. 16)
People don't have time to double check everything they read. As a result, misperceptions go viral, like the one that says Rivera only pitched 60 innings in 2010, and that this is proof of something.
- In 2010 Rivera pitched 66.1 innings including the post season.
April 2011, GQ: "Those days are coming to an end. Mariano remains one of the best closers in the game, but he spends ever less time sawing off hitters' bats with his cut fastball: With the exception of his injury-plagued 2002, the sixty innings Rivera pitched last year
- were the least of his career."...
- 12 outs within 5 days at age 40.
- And he pitched 2 games in one day (and 2 saves) on May 26th, 2010 (the sixth time he has done this in his regular season career). The first was to finish the 5/25 game shortened by rain. Both were 1-run games and he pitched an inning in each. This may not be mentioned at all on free stat services most people see. I haven't seen any mention of it. I only know about it because I made a note of it when it happened.
Rivera's three 2 inning appearances in the 2010 regular season weren't recorded as "Saves" although they were more difficult because all 3 were tie innings in 'away' games. He received the Win for 2 of them:
- June 23 in Arizona, and
It should be mentioned that
- in 2009 he pitched
P.S. Nice to see someone bring up Mo's post season efforts when discussing durability:
8/12/11, "(Mariano's) had a couple days in a row where he's given up runs. I remember in 2009 he kind of got off to that slow start and people were saying is this the beginning of the end?," Girardi said. "And let's not forget, I think he threw two innings in Game 6 against the Phillies. He might have given us five outs against the Angels.""...
