The problem with not busting it on that 4-3 groundout is on that 1% time when the 2nd baseman bobbles it and gets Cano by a step, it looks bad. If your counterargument is "He's hurting himself long-term by not saving his body on mostly meaningless plays"...I understand. It's still frustrating watching someone not do something simple like "run" when he plays a game for a living for millions of dollars. And on a DP, yes, definitely run, every time. There's a great chance the guy running from 1st is doing everything he can to make sure you're safe.
The other aspect of this I noticed is Cano's fielding. He's brilliant in the field. But if there's a ball to his right, you can be sure he's backhanding it rather than getting in front of it. And if he muffs it, you're thinking he could have tried a little harder. But he's so talented, he really doesn't need to most of the time.
