While players that eventually deliver stolen bases and saves are often undrafted, power is far tougher to find on the waiver wire.Â It is extremely unusual that the current National League home run leader was owned in just over half of ESPN leagues a week ago, but he was not even the most added player. That distinction goes to a Cardinals starting pitcher.
Domonic Brown:Â He shot to the NL home run lead by clocking nine in his last thirteen games.Â His power is a legitimate tool, but he is not lofting the ball any more frequently.Â His GB/FB ratio is 1.42 but he has a sky high 30.2% HR/FB.Â His walk rate is only 5.1% and he is swinging at over half the pitches he sees.Â In yearly leagues this is a good time to explore selling high.
Drop for him:Â Norichika Aoki, Starling Marte, Michael Morse
Donâ€™t drop for him:Â Mark Trumbo, Jay Bruce, Jason Heyward
Michael Wacha:Â He is the latest product of the gameâ€™s best farm system.Â He dominated the Royals in his major league debut, retiring thirteen straight to start the game and allowing only two baserunners in seven innings.Â The performance was widely praised, but the usual rookie pitcher caveats apply.Â He was mildly disappointing in Triple-A, holding only a 2.27 K/BB through nine starts.
Drop for him:Â Jeff Locke, Tim Lincecum, Alexi Ogando
Donâ€™t drop for him:Â Matt Garza, Homer Bailey, Yovani Gallardo
Matt Joyce:Â He hit .299/.396/.584 in May with five home runs, three steals, and a 1.44 BB/K.Â His ISO is near .250.Â Following years of 12.5%, 12.3%, and 13.3% his HR/FB is sitting at 17.9%.Â His career wOBA against southpaws is .271, so try to rotate him out.Â A 20/15 season is very possible.
Drop for him:Â Michael Brantley, Vernon Wells, Garrett Jones
Donâ€™t drop for him:Â Gerardo Parra, Lorenzo Cain, Daniel Nava
Kendrys Morales:Â He hit .343 in May and drove in 23 of the 107 runs the Mariners scored.Â He turns thirty this month and is still theoretically in his prime.Â He reached 34 home runs in the only year he made 600 plate appearances. Â He is hitting for more power away from Safeco but still features a .377 home wOBA.
Drop for him:Â Lance Berkman, Ryan Howard, James Loney
Donâ€™t drop for him:Â Billy Butler, Adam LaRoche, Allen Craig
Wade Miley:Â He nearly beat Bryce Harper in the NL ROY race last year, but this season has not gone as well.Â In 2012, he walked 1.71/9, a stunning improvement over his 3.1 minor league rate.Â This year he is walking 3.2, and for a pitcher with a K/9 below 7.00 that can make all the difference.Â He is a strikeout liability and not worth a roster spot in standard mixed leagues.
Drop him for:Â Ryan Dempster, Jorge De La Rosa, Julio Teheran
Donâ€™t drop him for:Â Jeremy Hellickson, Josh Johnson, Kyle Kendrick
Dayan Viciedo:Â He was hitting .302/.361/.488 the morning of May 22.Â Sunday morning he woke up with a .252/.300/.403 line.Â His shaky plate discipline is not improving, he is chasing over 40% of pitches outside the zone.Â He is hitting more fly balls, but overall his power is down.Â Do not be surprised to see him bunch home runs together sometime this year.
Drop him for:Â Josh Reddick, Marcell Ozuna, Chris Carter
Donâ€™t drop him for:Â Jason Kubel, Michael Saunders, Raul Ibanez
A.J. Griffin:Â He allowed four earned runs in 5.2 IP in each of his last two starts.Â He has a quality 3.11 K/BB ratio, but is an extreme fly ball pitcher and is giving up 1.43 HR/9.Â He has some match-up appeal, particularly when pitching at home, but he is far from an automatic start.
Drop him for:Â Bartolo Colon, Andrew Cashner, Marco Estrada
Donâ€™t drop him for:Â Jeremy Guthrie, Phil Hughes, Tommy Hanson
Salvador Perez:Â Sunday marked his ninth game missed while on bereavement leave, but the team expects him back Tuesday.Â He is only eighteenth among catchers in fantasy value.Â While he is one of three at the position to be hitting over .300 he provides negative value in the other categories.Â His patience is down, as is his power.Â If his BABIP goes south there is really nothing to fall back on.
Drop him for:Â Victor Martinez, Evan Gattis, J.P. Arencibia
Donâ€™t drop him for:Â John Buck, Jason Castro, Russell Martin
