Let's begin this with the appropriate qualifier: It's early. Every team has approximately 150 more games on their schedule. Twenty-five weeks remain in the regular season.
But some players are off to bad starts that are raising major concerns. And if those struggles continue this week, those concerns could develop into full-blown panic among some fanbases.
A couple of the players on a bad slide are veterans who will surely get a chance to right themselves, as their resumes entitle them to the benefit of the doubt. But their teams also aren't in positions to wait very long, as they risk falling far behind in division races.
So here are five National League players who need to show something positive this week.
Please add your suggestions for anyone who needs a good week in the comments.
