Points leagues breakdown: closers, rankings and more

A sore forearm has forced Baltimore Orioles closer Zach Britton to the disabled list. Jonathan Dyer-USA TODAY Sports

The lead for this week's article was all ready to go. The topic of discussion was that of closer confidence in points leagues, and one of the primary examples of that of being a "sure thing" was going to be Zach Britton of the Baltimore Orioles. Having a closer who was a perfect 5-for-5 in save chances thus far in 2017 -- and 54 straight conversions under his belt -- manager Buck Showalter was not likely to have to do much thinking when the ninth inning rolled around this season. Britton was his guy. Period. End of story.

However, you know what they say about those best-laid plans. Left-forearm soreness suddenly befell Britton on Friday, and a trip to the 10-day disabled list is now underway. Suddenly, Brad Brach and Mychal Givens are going to become waiver-wire darlings for those fantasy owners looking to get a few extra five-point-plus outings out of their relief corps.

Take unexpected injuries out of the equation, though, and you still find a bevy of closers who, despite seemingly being locked into their roles at present, might not necessarily be locks to remain in that capacity throughout the many months to come. Yes, Aroldis Chapman and Kenley Jansen owners can feel fairly secure, but those "sure things" are still few and far between.
