Okay lets see what Wikipedia has to say:
Shuttlecock - 186mph
Jai-alai - 180mph+
Line drive - n/a
Inconclusive...
Further research...
Well, the maximum speed for a batted baseball cannot be greater than the sum of the speeds of the pitch and the bat swing. So if a 102mph fastball was met with the sweetest part of the bat swung at 75mph by Vladamir Guerrero, the fastest we'd be looking at is probably about 175mph, right off the bat. This considers that my estimate for bat speed is accurate: I have the feeling that a 75mph swing is a little generous. The fastest swing might top out around 65mph. I'm going to give the baseball last place.
Perhaps we can cheat, and abandon the rules of baseball, use a hollow alluminum bat, and some hollow, compressable ball with a hardend surface. Perhaps this setup with the strongest of professional players could reach 200mph+.
"An electronically measured ball velocity of 188 mph was recorded by Jose Ramon Arieto at the Newport Jai Alai, RI, on Aug 3, 1979."

This page also says:
"Jai alai is a popular game for gambling. The betting is similar to betting on hoss races. Wagers are taken for the win, place and show. Then there are such wagers as daily doubles, quinela and perfectas that can be put on each match. Daily doubles are on the 3rd and 4th events and the 10th and 11th."
Another page mentions betting $10,000 on Jai alai games.
Interesting.
So the wrap up:
Max Jai Alai ball straight out of the cesta - 188mph
Max shuttlecock off a raquet - 186mph
Max baseball off a wooden bat ~ 175mph
Max speed of hockey puck - 106mph
