I've heard Bob Feller threw 107 and I've heard Nolan Ryan's name thrown out there too as the fastest but don't know how fast...

109? Not acccording to Baseball Almanac.

4 Pitchers tied at 102 in a Major League game, and career minor leaguer Steve Dalkowski as probably the fastest of all time.

J.R Richards: Houston Astros 1980: 109 MPH

The Guinness book still lists Nolan Ryan with the fastest at 100.9 mph.

Joel Zumaya hit 103 this season, which equals the fastest recorded by anything approaching official recorded times:

JR Richards threw 109 mph in 1980 for the Houston Astros.

I never saw Feller but I have seen many of the modern day fireballers and Nolan Ryan was the fastest, when he busted them inside they hit the dirt as fast as they could.

it was in fact JR Richards for the Houston Astros in 1980 .

cheers !

Nolan Ryan:109 MPH

Note:Why? He couldn't beat the Mets!

1985- Sidd Finch: 168 mph

Sidd Finch was an aspiring monk who spent much of his orphaned youth in England, went to Harvard, dropped out after one semester and learned to pitch in the mountains of Tibet, flinging rocks and meditating. He was discovered by a Mets minor league manager who watched in awe as the gawky string bean would wind up - he looked like Goofy in the old Disney cartoons - and throw pitches so fast and accurate that they vaporized soda bottles standing 60 feet away. The radar guns read an unfathomable 168; Nolan Ryan's heater was just a changeup compared with this kid's.
