Variables assignments are not happening as intended. What am i missing?

Question

I have been working on a project to evaluate baseball statistics. I am working on a program that simulates a full game of baseball. For the program, I have created a function called at-bat that takes in a player's on-base percentage and determines whether or not the player gets on base, or gets out. I have created a while loop that says while outs is not equal to 27, continue the program. However, most of the time, the program gets stuck in an infinite loop, completely ignoring the while condition. I believe that there is some disconnect between what the variable assignment should be and what it actually is, however, I am not sure what I am missing. Any feedback would be greatly appreciated.

import random

first= {"obp": 383, "avg": 310}
second= {"obp": 370, "avg": 295}
third= {"obp": 465, "avg": 313}
fourth= {"obp": 351, "avg": 261}
fifth= {"obp": 281, "avg": 221}
sixth= {"obp": 314, "avg": 210}
seventh= {"obp": 297, "avg": 262}
eighth= {"obp": 337, "avg" : 269}
ninth= {"obp": 317, "avg": 277}
order = [first, second, third, fourth, fifth, sixth, seventh, eighth, ninth]

outs=0
total_runs=0
on_base=0
game_log=[]




def at_bat(player):
 x=random.randint(1,1000)
 if player["obp"] >= x:
     print("ON BASE: " + str(on_base))
     return "on_base"
 else:
     print("OUTS: " + str(outs))
     return "out"
     



while outs != 27:
 for a in order:
     if at_bat(a)=="on_base":
         on_base+=1
     else:
         outs+=1



print("Outs = " + str(outs))
print("ON base = " + str(on_base))```
