I defined the Top 5 starters on each as the five pitchers who made the most starts. Simple enough. But KingRyan observed, sensibly enough, that the Arizona Diamondbacks didn't exactly regard Randy Johnson as one of their extra starters.
Which implies that it would be profitable to juggle the numbers once again. But instead of simply taking the five guys who made the most starts and calling them the Top 5, we would begin with the five starters each team trhought of as their starting rotation as the season began. We'll call them the Original 5. And then we would really see how the extra pitchers contributed. (We'll call them the Replacements - and hey! A shout-out to Paul Westerberg! When you're forced to call on the Replacements, you may have to Let the Bad Times Roll!)
Just shuffling the numbers in the spreadsheet is simple enough, but a few Command Decisions were required because of pitchers who were injured as the season began. These guys basically fall into two camps:
a) pitchers who weren't expected to return until after the All-Star Break. Here we're thinking of Pedro Martinez, Kenny Rogers, and Mark Mulder. They are not considered part of the Opening Day rotation.
b) pitchers who were expected to return before the end of April. This group includes Chien-Ming Wang, Randy Johnson, Bartolo Colon, Cliff Lee, and Esteban Loaiza. They are considered part of the Opening Day rotation. The men keeping their seat warm are not. And that group includes Fausto Carmona and Chad Gaudin, who would end up spending the entire season in their team's rotations. But here, they line up among The Replacements. The specifics of those cases are:
Arizona: Edgar Gonzalez replaced Johnson in the rotation to start the season, and went into the bullpen when the Big Ugly one was activated.
Cleveland: Fausto Carmona made the opening day roster filling in for Lee. He stayed in the rotation when Lee came back, because Jake Westbrook went on the DL at the same time. By the time Westbrook came back, in late June, Carmona had an 8-2 record and it was Jeremy Sowers (1-6) who was sent to the minors.
Oakland: Esteban Loaiza was only supposed to miss one, maybe two starts - as it happened, he didn't return until August. Gaudin was being described as an emergency starter when he replaced him in April.
New York: Darrel Rasner replaced Wang to open the season, and then stuck around replacing Pavano when Wang came back until a line drive off his pitching hand ended his season in early May.
Los Angeles: Joe Saunders opened the season filling in for Bartolo Colon. He went to the minors when Colon returned in April.
So which Original 5 stood up best through the next six months. (Drum roll, if you please...)
The Chicago White Sox.
The White Sox? Who went 72-90? It sure did them a lot of good.
The White Sox weren't the only team whose Original 5 starters ended being their Top 5 starters. Others were the Seattle Mariners, Boston Red Sox, Milwaukee Brewers, Houston Astros, Pittsburgh Pirates, and Detroit Tigers.
Many teams made it through the year with four of the Originals making the Top 5: Arizona, Cubs, Angels, Mets, San Diego, Cincinnati, Colorado, San Francisco, Cleveland, Atlanta, St.Louis, Texas, Dodgers, and Kansas City.
Teams with three Original 5 starters endig up in their Top 5 were: Tampa Bay, Minnesota, Philadelphia, Florida, Yankees, Baltimore, Oakland, and Washington.
The Blue Jays were the only team who saw only two of their Original 5 end up among their Top 5. And it worked out pretty well for them.
So let's first go around the majors and identify the Opening Day rotation. I think this is also the actual order in which they appeared, as well the number of starts they ended up making:
