It's easy to second guess the manager but hard to argue letting Nola in with a no hitter to that point.
First hit, ground single, and a run to tie the game. Looks like no win for Nola today. Looking back, he left Nola in too long, but looking back is always easy. In the end, the two walks were what really cost him.
Really a shame for Nola to pitch as well as he did today and not get a win.
