The second half just started, and you’ve already set your lineup once. Time to do it again.

That is, if your league treated the first weekend after the All-Star break, meaning Thursday through Sunday, as its own distinct scoring period. Some instead opted to combine it with the first full week for a supersized 11-day scoring period. If that’s your league, then this article doesn’t apply to you. Check back in during what will officially be known as Week 19 (July 27-Aug. 2), though it will almost certainly be known to you as something else due to your combined weeks throwing off the numbering scheme. Way to go.

For the rest of you needing to set your lineup again Monday, I have some hitters to stream, as usual. Also, as usual, I’ve limited my selection to those rostered in less than 80 percent of CBS Sports leagues. All information is up to date as of late Sunday.
