I find it interesting that the Rangers (#1 on the list) were going through pitchers so fast during the middle of the game that even though the Starter went 4 innings (not bad for a list like this), the Closer still had to pitch 2.

The closing trio the Stros had that season -- Lidge, Dotel, and Wagner -- was pretty remarkable. That was Lidge's first full season; Wagner left as a FA in the off-season and Dotel wss traded away the next year. Lidge's ERA was "only" 3.60 but he had the great K-rate and (I assume) the devastating fastball/slider combo. Must have been a fun bunch to watch. Each pitched at least 85 IP; just 7 seasons later that seems remarkable. How many teams have had three relievers pitch that much. No easy way to be sure since the PI doesn't break down SP/RP splits, but if we just search for guys who relieved every game (as this trio did), we find that the '03 Astros were indeed the last team to do that. 22 other teams matched it from 1962-1999. The 1982 Red Sox had 4 full-time relievers with at least 85 IP. I wouldn't be surprised if there's a few other teams who made it but the relievers in question also had a start or three.

The Astros trio also each struck out at least 97 batters. Not as aesthetically pleasing as if it were 100, but nearly as dominant. No other trio of full-time relievers has matched that. A few teams had two.

Dotel and Lidge finished 1-2 in holds (Lidge tied with some others), while Wagner was 3rd in saves. They combined for 110 saves+holds and 10 blown saves. Not sure of any easy way to compare that to other trios, but it seems pretty good. The Astros did have the third fewest blown saves in the league that season.

The Houston trio each had at least 2.2 WPA, one of nine full-time reliever trios to do that. And they each had at least 1.4 WPA/LI, one of six trios to do that (and the most recent, along with '03 Dodgers).
