i have these two SPs in my rotation hitting 1st year arb. they're not aces but have been solid for me:

asking 1.0 mil: Hardball Dynasty – Fantasy Baseball Sim Games - Player Profile: Bum Tremie

asking 1.2 mil: Hardball Dynasty – Fantasy Baseball Sim Games - Player Profile: Karim Jose

i have this guy in AAA, ready to make his MLB debut: Hardball Dynasty – Fantasy Baseball Sim Games - Player Profile: Esteban Ozuna

also this guy: Hardball Dynasty – Fantasy Baseball Sim Games - Player Profile: B.C. Cedeno

I like the arb guys but i could use all the salary felxibility i can get.

should i let the arb guys walk and bring up the young guys? should i hold onto one arb guy to let ozuna get his 25 games at aaa for the extra year? if only one, which one should i hold on to? should i hold on to both for safety regardless if i call up both kids? should cedeno stay down one more year?

You could go with almost any of those scenarios.  1 and 1.2 million are really cheap prices for ML players.   You could give them one more season at those prices, as they'll both be asking for at least double that next arb if you play them regularly.    Or you could release them and hope to sign at least one of them for cheaper in regular FA.  If that blows up in your face, you still have SP depth in the minors in the form of Ozuna and Cedeno.   I would only call up Ozuna and/or Cedeno early (as in 23 games in this season) if I felt that they were the final pieces of a contender.
