The Sixth Man

No one ever talks about the Sixth Man.

Well, they don't. In the springtime, no one ever worries about a team's sixth starting pitcher. Never mind the seventh.

Maybe we should. Because your five starters are not going to start 162 games. It happens every few years, to one team, but that's about it.

You are going to need more than five starters to get through the season. Get used to it.

By some strange coincidence, the two teams that sent their Top 5 starters to the hill the most often this past season both played in Chicago. The White Sox got 150 starts out of their top five guys - the Cubs got 152. The Cubs needed the sixth man just 10 times in 2007.

Ten starts - that's still having someone else in the rotation for about two months of the season. And these were the teams at the far end of the discussion. Most teams end up sending their sixth (and seventh, and eighth) man to the hill as often as they send their best guy. Some teams much, much more often.

A word on method. I am defining the Sixth Man by how it all shook out in the end, not by what the team's plans may have been as the calendar turned from March to April. The Top 5 starters, for every team, are the five men who started the most games. In the case of the Blue Jays, that includes Shaun Marcum, who began the season in the bullpen. And it includes Dustin McGowan and Jesse Litsch, who began the season in the minors. Gustavo Chacin, who was injured, Tomo Ohka, who was released, and Josh Towers, who was sent to a corner, were all part of the rotation when the year began. They became Sixth Men. They evolved. Or de-evolved, as the case may be.

So how often did each team need to go beyond the five men who started the most games, and who got the call?

The tie-breaker used, when deciding who was the fifth man and who was the sixth, was innings pitched. Hence Maroth over Miller (Detroit), Tomko over Hendrickson (Dodgers), Saunders over Colon (Angels), and Jennings over Albers (Houston).

Some familiar names in there, generally pitchers who would have been counted on to be part of the Top 5 but missed large parts of the season because of injury (Randy Johnson, Kenny Rogers, Jason Schmidt, Bartolo Colon).


In view of how much work these guys do, it matters how well they do it. And so - a Data Table!

Another thing we could examine is the drop-off between a team's Top 5 starters and the guys filling in. So let's make a more extensive Data Table, and this time we'll rank them by the size of the drop off. There ought to be a drop, after all - the Top 5 starters are supposed to be better than the other guys, right? That's why they're starting more games.

As you can quite clearly see, Milwaukee got much better work from their extra starters than they did from the top five guys. Uh, Ned Yost? What the hell? You got explaining to do, man...

Not really. Like the Blue Jays, the Brewers came up with some promising young pitchers this season - unlike the Blue Jays, however, they didn't find an urgent necessity to put them into the rotation in May. Yovani Gallardo filled in briefly for Chris Capuano in mid-season, and went into the rotation to stay whenh Ben Sheets went out in July. Gallardo pitched so well - he finished up 9-4, 3.74 - that it was Capuano who was bumped from the rotation when Sheets returned. And Carlos Villanueva was even better than Gallardo, albeit in very limited action (2-2, 2.06 in 6 starts.) Seeing as how three of the Brewers regular starters - Capuano, Dave Bush, and Claudio Vargas - all had ERAs on the wrong side of 5.00, I'd say the Cubs can consider themselves just a little lucky.

Gallardo was by far the best of the Sixth Men of 2007 - his 9 wins were three more than anyone else, he was the only to work more than 100 innings, his ERA was the best of anyone who pitched more than 50 innings. Only Bartolo Colon and Matt Albers (who were both tied for game starts with the fifth man on their own club) started more games. Galardo is a Sixth Man because he was a mid-season callup - he succeeded admirably, and will be one of the Top 5 next year.

The Red Sox did very well with their extra starters. Clay Buchholz pitching a September no-hitter got most of the attention, and they also featured the wonderful return of Jon Lester (4-0, 4.72 in 11 starts.) The good work turned in by Kason Gabbard (4-0, 3.73 in 7 starts before going to Texas in the Gagne deal) was also a factor.

The work of the sixth men may have had a decisive impact on the NL East. The Braves, as I noticed just the other day, had the best Pythagorean record in the division, despite finishing in third, five games behind the Phillies. Mike Hampton, expected to be the third starter, was unable to pitch a single inning this season, and Braves ended up in a world of hurt. The fourth and fifth starters (Carlyle and Davies) weren't very good - they went 12-15, with ERAs over 5.00. And the guys they turned to after that were a disaster: 5-15, 7.03. Schuerholz will be looking for starting pitching this winter, and he will most likely be dangling a proven, quality major league shortstop in his quest to acquire some.

Of course, the Mets had it almost as bad (7-14, 6.51), despite the fact that one of their sixth men was a fella named Pedro Martinez, who pitched rather well indeed in his five starts.

The Padres had the largest fall-off between the top starters and the ones who filled in. The Padres lost their ticket to the wild card by a single game, but they probably weren't hurt as much by their extra starters as the Braves were. The Padres extra guys managed to go 5-6 despite the unsightly 7.21 ERA - and the ERA is largely the work of one man, Tim Stauffer. He started twice, and allowed 18 runs in 7.2 IP. The Padres actually won one of those games (by an 18-11 score.)

The Padres had the largest fall-off in ERA from the top five guys to the bottom of the barrel. Several other teams actually got worse work from their fill-ins, but the drop off was nowhere near as dramatic. The Padres staff, starring Jake Peavy, Chris Young and a stellar bullpen (working in the best pitcher's park in history) had the best ERA in the majors.

There is almost no overall difference in performance by starting pitchers across the two leagues. The Top 5 starters from AL teams went 710-652 with a 4.35 ERA in 1851 starts; NL Top 5 starters went 744-706 with a 4.36 ERA in 2082 starts. The men who filled in were equally similar across the leagues. AL Sixth Men went 104-159 with a 6.00 ERA in 417 starts; NL Sixth Men went 124-214 with a 5.99 ERA in 512 starts. How close is that?

Overall, AL starters as a whole had a 4.61 ERA, NL starters had a 4.64 ERA. The slight edge to the AL comes entirely because the Top5 starters worked 82% of the games in the AL, as opposed to 80% in the NL.

But all this leads to another issue - the level of offense in the two leagues. There was a little more offense in the AL than the NL this season, but not much - AL teams averaged 4.9 runs per game, NL teams averaged 4.71. The NL ERA was 4.44, the AL ERA was 4.52. The American League has the Designated Hitter, which is a huge difference maker - but the National League now has a host of terrific hitter's parks, in Denver, Chicago, Philadelphia, Phoenix, and Cincinnati.

For some reason, I think we have assumed that the presence of the DH meant that run scoring was up by about half a run a game in the AL, and that ERA would be about 0.50 higher. That wasn't the case in 2007. Is this a new thing?

No. The difference in offense between the two leagues in the 35 years of the DH era has exceeded .5 runs per game exactly twice: in 1994 and 1996. And it's been smaller than the 0.19 runs per game in the season just concluded: as recently as 1999 and 2001, as far back as 1974 (when the NL actually outscored the AL, DH or no DH.)

So, while we're all here, let's track the difference in runs scored per game across the two leagues. We shall require one last Data Table, and possibly a pretty picture!
