[USER (data scientist)]: Can you show me how to get only the grass court matches between top 10 players in the last five years? Please generate and display a DataFrame containing head-to-head matches on grass surfaces between players in the top 10 rankings in the ATP tennis dataset.
My template of code snippet is:

---BEGIN CODE TEMPLATE---

import pandas as pd
import numpy as np
import pickle
from decision_company import read_csv_file,

# please import the necessary private functions from decision_company first

atp_tennis = read_csv_file('atp_tennis.csv')

# YOUR SOLUTION BEGIN:
<code1>
[COMPLETE YOUR CODE] 
</code1>
# YOUR SOLUTION END

print(head_to_head_matches)

# save data
pickle.dump(head_to_head_matches,open("./pred_result/head_to_head_matches.pkl","wb"))

---END CODE TEMPLATE---

[YOU (AI assistant)]: Sure! Here's the code to filter the dataset:
'''
import pandas as pd
import numpy as np
import pickle
from decision_company import read_csv_file,

# please import the necessary private functions from decision_company first

atp_tennis = read_csv_file('atp_tennis.csv')
