DateQuestionAnswer
2014-03-14 09:00:00 (link to chat)I have a few pitchers on my roster in a Dynasty League who I have idetified as good "sells" - Francisco Liriano, Hisashi Iwakuma, and Michael Wacha. Do you agree and can you think of other specific pitchers you would be selling? Conversely, who are some pitchers you would be trying to buy?
(Shawnykid23 from CT)
It all depends on the context of where you're at in your success cycle. Do you have a shot at winning this year? If you do, while Taijuan Walker is likely a better long term play than Liriano, you're better off with Liriano - at least for now. Some of this also depends on how easily you can fill in with replacements. I'd only be selling pitchers like Liriano if I were in a rebuilding mode...or if I could get a pitcher like Walker on the cheap.

I don't necessarily agree or disagree with this approach. I think I would need more information about your team/situation before I could comment on whether or not it's a good or bad idea to sell these guys. I'm not sure, though, why you'd sell Wacha. He might struggle this year (and people might be overpaying for him for 2014) but I like the long term outlook. (Mike Gianella)
2013-09-26 13:00:00 (link to chat)20 team dynasty, h2h. I've got an elite offense say for my dh (Victor Martinez). My bullpen consists of Red Dragon and many one day/would be closers. My rotation is from heavy (Strasburg, Cain, Moore, Wheeler, Gausman, Taillon, Carlos Martinez, J. Mejia, Collmenter(???)). Pitching is king in this league, regardless of offense. I have, through various trades, the 1-1 pick next year in a 2-round, 40 pick draft. Would you a) draft Buxton; b) draft Archie Bradley, N. Syndergaard, or Robert Stephenson; c) draft Jose Dariel Abreu (will know where he signs by then); or d) trade the pick for something immediate?
(AJ from Phoenix)
Even with pitching being king, I'd still lean Buxton or trade it for a now piece. Could you get like a Hisashi Iwakuma or is that too high? Test the market for a big arm or just go Buxton if the offers are uninspiring. (Paul Sporer)
2013-06-20 13:00:00 (link to chat)Hisashi Iwakuma.is he for real ?
(Spirou from Montreal)
So real! That doesn't mean he'll maintain a filthy 2.06 ERA, but I think he will remain a very strong fantasy asset. I'd bet on a 3.00 ERA the rest of the way and take anything better as a bonus. (Paul Sporer)
2013-05-07 13:00:00 (link to chat)Hisashi Iwakuma... talk amongst yourself.
(vigilantebsball from Seattle)
We are, he's here right now eating these grapes from me. (Paul Sporer)
2013-01-07 13:00:00 (link to chat)Who's a good buy-low MLB regular for SP this season?
(Sara from Tacoma)
I'll give you a few to cater to leagues of a variety of sizes. Hisashi Iwakuma is a sleeper I like a great deal. His high groundball percentage will help him in the transition to Safeco's new ballpark dimensions. Brett Anderson was impressive in his brief return to the hill at the end of last year and is currently a draft value at his current draft position in Mock Draft Central mocks. A few ugly starts to begin Ryan Dempster's time with the Rangers seem to have driven down his value. He'll be fine pitching in Boston and remains an undervalued starter. Chris Tillman enjoyed his first taste of success in the majors last year. He's not as good as his sub-3.00 ERA suggests, but some backlash from those looking at the peripherals may make him a value in AL-only in deep mixed leagues. I think he's capable of improving his underlying stats and staving off some of the regression that would otherwise come from him pitching at the same level this year. (Josh Shepardson)
2012-03-23 12:00:00 (link to chat)There are a couple of new Non-Darvish Japanese pitchers this year: Wei-yin Chin, Tsuyoshi Wada, and Hisashi Iwakuma. Will any of them have decent seasons in America?
(Paul from DC)
I like Iwakuma's chances more than Chin. Unfortunately, the Mariners gave Millwood a rotation spot over Iwakuma for now but that presents a bit of a draft day bargain. (Jason Collette)
2012-03-23 12:00:00 (link to chat)OK. List your top 5 late round, who the Hell is that guy sleepers. Any position.
(Billy from Wildwood, NJ)
Trevor Plouffe, Tyler Flowers, Brian Bogusevic, Hisashi Iwakuma, Brian Matusz (Jason Collette)
2010-12-14 13:00:00 (link to chat)Which agent has done the WORST job for his/her client so far this off-season? (in other words, why is Beltre still unemployed?)
(dianagramr from NYC)
Beltre will get his money, so I wouldn't tab his representation. Instead, I'll try not to let my disappointment show when I select Don Nomura for this winter's Jody Reed Award, for his failure to get Hisashi Iwakuma signed up stateside. (Christina Kahrl)
2010-11-09 14:00:00 (link to chat)WTG: Hisashi Iwakuma. What's his upside?How good are his secondary pitches?
(leites from New York)
Breaking ball is solid, that split/change thing he throws is a true plus pitch and the command/control is outstanding. Highest praise I've heard is a Tim Hudson comp, lowest I've heard is a solid No.4 starter. (Kevin Goldstein)
2010-11-11 13:00:00 (link to chat)Any thoughts on the probable effectiveness of the latest Japanese pitching import - Hisashi Iwakuma?
(Paul from DC)
Warning: economist cop-out answer. I don't have any idea how his stuff will translate other than the fact that 29 teams didn't think he was worth $17 million and 1 team did. I suspect that teams learned from Matsuzaka that it's smart to shade down your bids on an auction like that, but I still think the fact that $17 million wasn't outbid means something here. It means the experts in this stuff didn't think he was a top of the line starter. I doubt they're consistently underselling Japanese players, so I'm not terribly excited about him. Still curious, though. (Matt Swartz)
