Suggested by DarkLK Barry Allen is a very fast fighter but even he is a little too slow to deal with Bass. Bass would be running rings around him during the fight and a single move will be enough to end the fight. Bass is just too powerful and Barry has historically not been known for his great defense. He won’t know what hit him. Bass wins.

Pardon me, but isn’t Barry usually seen as the fastest of the Flashes? Since Bass is inside a virtual reality simulator, couldn’t that work against him?
Barry is really fast. I think Wally surpassed him, but I’m not sure. It wouldn’t work on Bass though since he is now able to operate in the real world and tends to wreck everybody in his path!
