I think the proposed deal is the 1B Goya for Pitcher #1 (mistakenly linked to Goya), Pitcher #2 Moore, and Pitcher #3 Karnuth, right?
Don't do it...it's a bad deal for you.
Pitcher #1 isn't a major league pitcher even if he reaches his projections (most players fall somewhat short) - his splits are just too low to be effective.
Moore would be a no go even if he was good (he isn't) because of the 36 Health rating. If you check his card you'll see that he's been on the DL at least once every season. His control and splits are too low for him to be good in the majors, and he's not going to get better (he's in his 6th pro season: generally speaking, development slows in the 4th year and slows a lot in the 5th year. There can be gains after that - especially for pitchers - but we're talking a point ayear in one or 2 categories. Nothing big).
Karnuth is in his 4th season and has 34 control - it'll probably never top 38. I've had a P have a good season with 44 control, but he also had both splits in the high 70's. Karnuth may reach 63-64 at best on splits.
Shop around some more. Goya's a pretty good 1B - you can get much better value for him than this offer (which is basically 3 minor leaguers, which is basically nothing). Look for contending teams who are weak at 1B or DH. Contenders get a little looser with the offers of prospects as the deadline approaches, so you might hold off until then. Generally speaking (there are exceptions), offers of multiple "prospects" are attempts to make up in quantity what's lacking in quality (the offer you have here is Exhibit A). Target one (1) prospect that looks like a pretty sure bet to be a major leaguer of about the quality of the veteran you're offering. If you can find a good prospect in an organization that has a young player at his position at the ML level, the owner might be more willing to make a deal.
