Charlie Haeger called up

You may not care about Haeger or the Dodgers, but you should care that the Law of Conservation of Knuckleballers has once again been vindicated:

Jeff Weaver will start for the Dodgers on Wednesday in place of Chad Billingsley, and Charlie Haeger will replace Eric Stults on the active roster to help back Weaver up, according to word passed along by Dylan Hernandez of The Times.

A 25-year-old knuckleballer, Haeger has a 3.55 ERA for AAA Albuquerque this season. Last year in the majors, he allowed eight earned runs in 4 1/3 innings.

(Thanks to Tripon for the heads up.)
