Incredible data available from Beyond the Box Score dissecting DL trips among Major League teams. You should check it out, but as a teaser I'll point out that...
-The Astros rank 2nd behind the White Sox in Fewest Trips to the DL
-The Astros rank 6th in Fewest Average Days on the DL
-The Astros are #1 in Fewest Days Lost to the DL
