How many moves do you have per week? Doesn't seem like a very active league, regularly active anyway...at the very least I would stream pitchers in that spot based on matchups...
...first I would consider picking up Latos, especially if he continues with his excellent start at San Francisco today...he may be turning the corner...Fister is a good pitcher too...all of the guys you mentioned have the opportunity to get hot...Parker is a 2-start option next week...with two good starts....Fister also has 2 starts...
...with limited adds, I'd roll with Parker for Monday at home vs. Boston and Sunday hosting Seattle...with more adds I'd go with the following:
Monday - Fister vs. MIN
Tuesday - try Bauer vs. SD (why not have some fun)
Wednesday - Leake @ LAD (he's pitching well)
Thursday - Latos @ SD
Friday - Masterson vs. TB
Saturday - Fister vs. KC (or go with Travis Blackley, Homer Bailey, or other)
Sunday - Parker vs. SEA
If Latos has a good game today (has a 1-hitter into the 6th right now), and if you think someone will pick him up, then go with him...he has an awesome matchup on Thursday.
Parker has a good 2 start week.
If Fister pitches well Monday (pretty good matchup) his value will increase...he may be undervalued at present...
...I wouldn't be afraid to drop Lynn, especially with that much depth on the wire...
