As if that wasn't enough, the Rockies also announced that Moyer will slot behind Jeremy Guthrie as the team's No. 2 starter.
Juan Nicasio, Jhoulys Chacin and Drew Pomeranz will comprise the rest of the rotation, but Pomeranz isn't scheduled to pitch until April 15 against the Diamondbacks.
After sitting out all of the 2011 season because of Tommy John surgery, Moyer pitched admirably this spring. He went 2-0 with a 2.77 ERA, including an 89-pitch outing in his last start against the White Sox.
Moyer out-pitched the likes of Tyler Chatwood and Guillermo Moscoso, who are a combined 50 years old.
When Moyer wins a game this season, he will be the oldest pitcher in history to ever win a major league game. Jack Quinn is the current owner of that record, as he won a game at the ripe old age of 49 years and 70 days.
It's all good and well that Moyer has made the Rockies rotation, but his every pitch will be closely watched.
At 49 years old, he's a walking health risk. Couple in the fact that he's coming off of Tommy John surgery, and the trainers will be out to the mound at the slightest grimace.
The contact-prone Moyer will also need to learn how to pitch at the hitter-friendly Coors Field, a place where he has only started two career games.
In those two games, Moyer has 11 runs in 11 innings. Opposing batters hit .370 against him with eight extra-base hits in those games.
If Moyer can overcome the odds and have a successful 2012 campaign, he'll likely be the best feel-good story of the season.
