Odd Ratio and Logistic Regression

Question

Windy and Play Tennis = 9 Windy and Not Playing Tennis = 8

Not Windy and Play Tennis = 14 Not Windy and Not Playing Tennis = 8

I performed logistic regression in Weka and got odd ratio as 0.3448 for playing tennis.

I am trying to calculate the odd ratio by hand but it didnt result as 0.338.

What is the steps for calculating the odd ratio?

Thanks You

EDIT: Still the result differs from Weka's result. My data set is below
