Picking saves is certainly possible, but it's only easy in a league that's not very competitive. If you're playing with competent and active managers you can pretty much guarantee that saves is the one category that everyone
is watching the wire for, so the rush to add new closers is pretty fierce.
That said, the advice to not make a one sided trade is spot on. It's not too early to trade for a closer, but it's always to early to over-pay for one. If there happens to be a guy in your league who's over stocked and willing to trade off a half-decent closer for a reasonable price then go ahead. Mostly that won't be the case though, since most everyone knows to put a premium on saves in a trade. I think an easier approach is to pay just as much attention to trends and hype in general. If you can grab a guy (at whatever position) off the wire who's getting a ton of positive press you may find it a little easier to deal for a closer when you have some hype on your side - the hype cancels out the closer premium (sometimes
Given your scoring system (which only caps games started, not innings pitched) I would say that you could use another RP of some sort, since that'll get you more counting stats without messing with your GS totals. If saves aren't available maybe think about adding a good middle relief type who's got a high K/9 and good ratios. Maybe just filter the available pitchers by 2009 stats and Ks and see if any of the relievers left look interesting. Make sure you do a little research to find out if their riole is the same this year of course.
You're going to be hurting until Strasburg gets called up anyway, but you can limit the damage.
One option is to do a little streaming with one or both of your bench slots (assuming Starsburg isn't getting dropped). That's where you add and drop guys constantly to maximize games played. The focus is on adding guys with favourable matchups. You'll get more value out a streamed slot than by holding on to a mediocre hitter for example. You can also pick and choose on the pitching as well, which is helpful when a lot of guys are only good on one half of a split (only good at home, or whatever). Streaming is more work for you, especially if you're actually paying close attention to matchups but it will pay off. The trick with streaming is iming the drop adds right, but it's not hard, just labour intensive compared to a set it and forget it approach.
