Keepers due tonight! Who is my #10 of 10? [Update Below]

12-Team H2H, Daily 5x5 (+OBP & QS)

This is the final year of a 3-year keeper and, after coming one H2H point from taking the championship in 2014 I'm ready to make a solid push.

Here's who I'm currently set on keeping:

-Mike Trout (Round 1)
-Freddie Freeman (Round 7)
-George Springer (Round 15)
-Corey Kluber (Round 16)
-Manny Machado (Round 17)
-Mookie Betts (Round 18)
-Jake Arrieta (Round 19)
-Jacob DeGrom (Round 20)
-Garrett Richards (Round 21)
-Yan Gomes (Round 22)

If I commit to the above I will have C, 1B, 2B, 3B, OF, OF // SP, SP, SP, SP filled, and I'll still be drafting in rounds 2-6 and 8-14. Not a bad start to a team, I think.

I'm not sure I would normally keep 4 SPs, but since I'm getting them all so cheap there's something really appealing about being able to fill out/upgrade my lineup early.

Here are four other keeper options:

-Ian Kinsler (Round 4)
-Chris Carter (Round 22)
-Rusney Castillo (Round 22)
-Javier Baez (Round 22)

Based on all of this I have two questions:

1) Are any of the four above worth swapping out for anyone I'm keeping?
2) If I stick to the above how do you think my team will look?
