Python pandas - how to access parameters of stats ols?

Using a Pandas dataframe and the stats ols method, Im able to run a regression using the code

import pandas as pd
from pandas.stats.api import ols
df = pd.DataFrame({"A": [56, 55, 57, 58, 56, 58, 59, 60, 63, 62, 63, 65, 66, 68], "B": [1,2,3,4,5,6,7,8,9,10,11,12,13,14]})
res = ols(y=df['A'], x=df[['B']])

However although this works

print res

Im trying to get just the fitted coefficient, and this does not work

print res.params

i get the error

AttributeError: 'OLS' object has no attribute 'params'

how can I access the parameters, I am particularly looking the extract the coefficient of the regression, that is all I am interested in.
