If it's the seventh inning, and the Mets are up by 4, and Noah Syndergaard has thrown 95 pitches, and Bryce Harper is up with nobody on base, then yes, I'd let Syndergaard pitch to him. But if the batter, inning, and pitch count are the same, but the Mets are up by one and there are two runners on base, then maybe it's time to bring in a reliever.
