Starting pitcher recommendations?

Just getting in to ranked. Off to a nice 5-0 start but it's clear I will need starting pitching help beyond 99 Kluber and 96 Hamels.

After I took a loss on the ducks packs, I'm sitting at 162k stubs. I figure I need 2 more starters, and I'm considering..

97 Sixto (60k)
97 May (78k)
97 Greinke (30k)
93 Oswalt (31k)
93 Blue (15k)

Pick 2, or save my stubs and grind for teamaffinity pitchers?

Oswalt and Grienke, then grind for Kyle Wright or lodolo

Grenkie and Blue.

Greinke is great for the price. I would also wait for the 5th inning program because there could be a 99 starter that you can get for free.

Blake Snell is easy to get too and he is my #2. You should acquire him.

Bought Greinke, shut down the guy with him. I'll probably save the rest of my stubs for later.

Blue is my best pitcher by far. His delivery and speed differential on fb/change plays up big time. Definitely worth the cost.

I liked greinke alot too, wont blow anyone away but good control and pitch mix to get outs over 7+ innings and again for the price cant go wrong.

Save stubs over chasing 96-97 ovr guys who will obsolete soon enough

Oswalt and Grienke/May. Definitely Oswalt and you cant beat Grienke for the value, although I like May.

I also would vote for Oswalt. I'm five RS Innings away from Prestiging him, and he has the best control in my rotation.
