Geez! My fault. Practically every team. Now counter that with teams that have two like the Cardinals, Oakland when they had Gonzalez who is now with the Nats and Strasburg. Look around at the rotations and see their teams versus the Cubs. Sure, their may be an exception, but the point is they developed.
The Latos for Alonzo trade was young player for young player. Had Latos been in the same class as Price, he would have cost a ton.
My point of this whole thing is develop your own pitchers. I don't want to go backwards any more. Some may be okay with it, and that's there choice.
To get a David Price, it will cost prospects because teams like Tampa aint gonna take Anthony Rizzo in a trade because they don't want to take on salary.
Rizzo and Castro are the ones who should be in trade discussions for pitching, not Baez and/or Bryant. They continue to struggle, so then they are not worth much.
Well this ought to be good...
Angels - Jared Weaver 1st round (12th pick) though Wilson was actually a better pitcher last year and he was a FA
Astros - yeah they got nothing atm unless you're relying on prospects
A's - Colon was their "ace" last year an he was a FA. No other pitcher the had produced more than a 2 WAR.
Jays - Dickey I guess is their "ace" and they gave up the farm to the mets to get him. He also had a terrible year. Buehrle produced more WAR and he was a FA
Braves - Mike Minor 1st round (7th pick) was their best pitcher but I'd hardly call him an ace. Probably more of a fringe #1 type. But I'll humor you and count him.
Brewers - Lohse was their best pitcher last year and was a FA. Yovani Gallardo(2nd rounder) was close but neither was even as good as Shark in terms of WAR so I don't think they count.
Cardinals - Adam Wainwright(1st round (29th pick) by ATL acquired in JD Drew trade). Lynn(1st round (39th pick)) was decent but more of a #2. Shelby Miller(1st round (19th pick))
Cubs - obviously very little at the MLB level
D-backs - Patrick Corbin(2nd rounder drafted by LAA acquired via Dan Haren trade) was their best pitcher.
Dodgers - Kershaw(1st round (7th pick)). Grienke is also #1 quality but he was a FA
Giants - Bumgarner(1st round (10th pick))
Indians - Justin Masterson(2nd rounder) is more of a #2 and was acquired via trade with the redsox for Victor Martinez
M's - Felix Hernandez(IFA), Hisashi Iwakuma was signed via posting process
Marlins - Jose Fernandez(1st round (14th pick))
Met's - Matt Harvey(1st round (7th pick))
Nationals - Stephen Strasburg(1st round #1) probably would be their ace when healthy though Jordan Zimmermann(2nd rounder) has pitched more/better than him the past several years
O's - Wei-Yin Chen was their best pitcher last year and he was posted and clearly wasn't a "ace"
Padres - Cashner was likely their best pitcher acquired via trade for Rizzo though I'd struggle to call him an ace. He had a 4.00 ERA on the road and a 1.95 ERA at home. Probably more of a #2/3
Phillies - Lee was their best pitcher but traded for. Hamels(1st round (17th pick)) counts though.
Pirates - Burnett and Liriano were their best two pitchers. One was a trade the other was a FA. Cole MIGHT be one but I think its a bit early to call it.
Rangers - Darvish was posted. Derek Holland(25th round) counts.
Rays - David Price(1st round 1st pick) counts.
Red Sox - Jon Lester(2nd round) was their best pitcher last year. Buchholz(1st round (42nd pick)) probably also counts
Reds - Mat Latos was traded for. I'll count Bailey(1st round (7th pick))
Rockies - Jhoulys Chacin(IFA) was their best pitcher. I REALLY struggle to call him an ace.
Royals - Shields was their best pitcher who they traded for.
Tigers - Sanchez and Scherzer were their best pitchers last year and they were traded for but I'll count them for Justin Verlander(1st round (2nd pick))
Twins - The got nothing worth talking about
White sox - Sale(1st round (13th pick))
Yankees - CC Sabathia was their "ace" and they signed him as a FA.
So even being fairly liberal in what you consider an "ace," only 16 of the 30 teams have home grown players that turned out that way. And of those almost all of them were top 15 picks many being top 10 picks.
Edit: to answer your earlier question why don't the cubs have someone like these guys, simple. They haven't drafted a pitcher in the top 15 picks since Prior at #2 in 2001. Bobby Brownlie was the 21st pick. Luke Hagerty was the 32nd pick. Chadd Blasko was the #36 pick. Matthew Clanton was the 38th pick. Mark Pawelek was the 20th pick. Andrew Cashner was the 19th pick. Hayden Simpson was the closest at 16. Add that to the fact that Hendry in general didn't produce much in terms of draft picks until his last draft. I seem to recall them not being very active in the latin america either though they did produce Castro and Zambrano out of that. So, I'm not sure if I'm just being revisionist there or if that was actually a thing.
