Throwing a curveball – why not bowl one?

I nearly got to watch a live baseball game at the weekend…until persistent rain caused the game to be called.

But I was thinking about what baseball pitchers do with a baseball – and it’s a lot more than just hurling it through at 100 mph. They use spin-swerve to get the pitch off straight, and curveballs add over-spin to add dip to the mix.

It’s the same effect as David Beckham uses to get the ball up and over the defensive wall, and curving into the top corner.

So it works in baseball, and football (and golf, and tennis); some descriptions of the finger spinners arm ball sound like spin-swerve, and Shane Warne’s “ball of the century” to Mike Gatting surely had a bucket load of spin-swerve on it. But I don’t think I have ever heard a cricket commentator talking about any one using spin-swerve at medium pace or above, and the only coaching book where I have seen it described is Alan Wilkins “The Bowler’s Art” (a fascinating technical read, by the way).

Now, it possibly is easier for a pitcher to generate spin-swerve when he pitches than for a bowler to do the same, but is anyone trying? Reverse swing was invented to compensate for the lack of conventional swing with a shiny ball. Apparently, SF Barnes used spin-swerve in the early years of the 20th century, to capture 189 wickets in 27 Tests, so it could certainly be done in the days when there was no second new ball.

So why does no one add spin-swerve to the fast and medium-pacer armoury?
