At 49 years old, Colorado Rockies pitcher Jamie Moyer is still going strong. Moyer lost his bid to become the oldest pitcher in Major League Baseball to record a victory, but the goal continues as he's part of the Rockies rotation.

Moyer's longevity is impressive; the 49-year-old got his start in Major League Baseball with the Chicago Cubs in 1986.

Moyer's age has been a fascinating topic to Twitter users who have dug up interesting facts on the Rockies hurler. For instance, Moyer has pitched to 8.9 percent of all the hitters who ever played Major League Baseball, a stat shared on the micro-blogging site by baseball writer @Bill_TPA.
