Вы можете использовать re:

import requests, re
from bs4 import BeautifulSoup as soup
d = soup(requests.get('http://m.mlb.com/tb/roster').text, 'html.parser')
headers = [['td', 'dg-jersey_number'], ['td', 'dg-player_headshot', lambda x:x.find('img')['src']], ['td', 'dg-name_display_first_last', lambda x:re.findall('\d+', x.find('a')['href'])[0]], ['td', 'dg-bats_throws'], ['td', 'dg-height'], ['td', 'dg-weight'], ['td', 'dg-date_of_birth']]
def get_data(d):
  return [[lambda x:x.text, None if not c else c[0]][bool(c)](d.find(a, {'class':b})) for a, b, *c in headers]

final_results = [get_data(i) for i in d.find_all('tr', {'index':re.compile('\d+')})]
