With all the changes going on with the closers around baseball, we are going reliever-centric with this week’s “Buy And Sell” for pitchers. As always, send me any feedback via Twitter @bradberreman24.

Buy

Heath Bell, RP, Miami Marlins

Bell has struggled thus far in his first season with the Marlins, sporting a 10.03 ERA in 14 appearances (11.2 innings) along with eight strikeouts and 12 walks while converting three out of seven save chances. He was briefly removed from the closer role, but manager Ozzie Guillen has recently announced he will get the job back. Whether that holds true is up in the air, and the Marlins have played much better in May after struggling early. So there looks likely to be plenty of save opportunities to be had, and Bell should get every opportunity to keep the job with the contract Miami gave him over the winter. All things considered, things are not likely to be much worse for Bell and the opportunity to buy very low on him is here if the owner that has him in your league is desperate to unload him.

Kenley Jansen, RP, Los Angeles Dodgers

Jansen recently replaced Javy Guerra as Dodgers’ closer, and he has not disappointed by converting two straight save opportunities. He is now 2-0 with a 2.29 ERA in 19 appearances (19.2 innings this season) with 30 strikeouts and eight walks and seven holds. Jensen has allowed just one run over his last 14 appearances dating back to mid-April, so it looks like he is the closer for the Dodgers for the foreseeable future. Even if he were to struggle and be removed from the role at some point Jensen offers fantasy owners elite level peripherals, particularly strikeouts, so he would retain some value as long as he is healthy. His ownership percentage is certainly on the rise right now, but there could still be a buying opportunity here in a trade if you have depth elsewhere on your roster and need bullpen help.

Sell

Sean Marshall, RP, Cincinnati Reds

Marshall converted his sixth save of the season, and the first for him in May, Monday night against the Atlanta Braves and he is now 1-4 with a 4.15 ERA in 14 appearances (13 innings) this season. With Ryan Madson (elbow) out for the season, the Reds are looking for a closer and Marshall has fit the bill to this point. That said, it may only be a matter of time before hard-throwing Aroldis Chapman gets an opportunity to close games and if Marshall has a couple rough outings in a row his leash may get short very quickly. It’s a big question if Marshall can maintain the closer-worthy peripherals he has to this point in the season (13.2 K.9), and his track record (7.6 career K/9 rate) would suggest he can’t even with good control (just three walks this season). Marshall’s fantasy value may not get much higher than it is right now, and if you are an owner that has been hit by injuries to position players it may be time to trade him for something of value.

Frank Francisco, RP, New York Mets

Francisco’s hold on his role as Mets’ closer looked tenuous after two bad outings in a row last Friday and Sunday, but manager Terry Collins elected to stick with him and he picked up his ninth save of the season Monday night against the Milwaukee Brewers despite allowing one run on two hits in his inning of work. He has only blown two saves so far this season, but has an ugly 8.59 ERA over 17 appearances (14.2 innings) along with 16 strikeouts and eight walks. The Mets have other options to close games, including Jon Rauch and Bobby Parnell, so if Francisco continues to struggle (six runs allowed over his last three outings) a change is likely to come. Now looks like the time to dangle him in trade talks to an owner in your league that needs saves while something valuable could still be acquired.

Another week in the books another chance to look around the league and figure out who we need to add to our rosters and who we need to just cut bait with. Let’s check out this week’s Buy & Sell: Batters.

Buy:

Andy Dirks, OF (Det) – Apparently only 25% of all Yahoo fantasy owners have taken notice what Andy Dirks has done over the course of the 2012 season; he’s been hitting .371/.413/.629 with 3 HRs and 11 RBI along with 5 doubles and 2 triples. Do we expect him to sustain those numbers over the course of the season? No, not at all. But these last 10 games he’s been red hot, and with a number of outfielders going down (Desmond Jennings the latest), Dirks is one player you should scoop up and ride him while he’s hot.

Alright, here's a quick 2 Start pitchers update featuring some young pitchers.  I'll continue to emphasize that pitching is deep and that this is a viable strategy, and if you're convincing enough you can take budding young stars on a hot streak, and parlay them into a trade up for perhaps a struggling ace or position player.  We're about 6 weeks into the season, so now is the time to reallu start analyzing your teams to see what you need to improve on.

Christian Friedrich - He won his major league debut last week, and now it's time to jump on the bandwagon especially because he may be able to get you two wins this week.  Don't get too excited because his major league debut was against the Padres, but he continues to have an easy schedule this week facing the San Francisco Giants and Seattle Mariners.  Additionally, if you also want to play this matchup, Jeremy Guthrie has the same matchups for the Colorado Rockies.
