Who has thrown the fastest pitch in Major Leauge history and how fast was it?

[skaterman32]

The greatest reliably recorded speed at which a baseball has been pitched is 100.9 mph by Lynn Nolan Ryan (California Angels) at Anaheim Stadium in California on August 20, 1974.

Mark Wohlers was clocked by radar throwing 103 MPH in Spring Training in 1995. Joel Zumaya matched this in 2006 while pitching at the McAfee Colesium in Oakland, but they say Nolan still holds the record because those guns are dodgy.

Radar gns are pretty lame IMO.

Anthony Reyes for example threw like 93-95 mph in Memphis, and when he got called up he threw 90-91 mph.

I'd go with Joel Zumaya

I believe Nolan Ryan has the fastest pitch record at around 103mph but Joel Zumaya also threw 103mph so they share the record
