I did some hitter streaming this week. Dropped Billy Butler for A.J. Pierzynski and A.J.'s start on Thursday, filling my otherwise empty C spot. A.J. paid off with a 1 for 3 and a HR.

Next day I dropped A.J. for Melky Cabrera.
There are more than seven weeks left in the season. This time of year, many managers pay less attention to FB because they're out of the race and football is coming around ... meaning competition for WW players is less than it was in say May and June. Over seven weeks, I'm pretty confident a streaming strategy in roto for both hitters and Ps can pay off with a few points in the standings.
Of course you can drop a bench hitter for an middle reliever, net a few Ks and low ERA and WHIP (hopefully!) until Monday or Thursday, then drop the MR for hitter to plug a hole given the abbreviated MLB schedule. Or a spot starter against a weak team -- e.g., Shaun Marcum Friday 8/10 vs. KC.
It also pays if you have the time to check your lineups an hour before gametime to ensure your starters are indeed starting ... especially important in mid to late September when lots of starters get a day off. Andy Behrens had a pretty good "Roto Arcade" column on this topic today:
So if you're in the middle of the pack in R and RBI in a public league, and you're 18 games off the games max at OF, which of these options do you think will be more valuable: owning Casey Blake for the remainder of the season, or owning the best available free agent outfielder every day, whether it's Blake or another player?
I'd take the latter option. It's not really a difficult choice, either. Think of the free agent pool as your fantasy team's farm system. You can call those guys up whenever it's necessary. If you're way behind the pace in games and innings, it's probably necessary right now.
