Eighth chance at some free Chrome...could this be the last hint?

This is chance #8 to win some free Chrome.

I pulled a yellow refractor from my 2013 Bowman Chrome Blaster.  They are numbered to 10 so we’re having another contest.

You need to guess the correct player and the correct number.  The first person to do so will win their choice of a value pack of Bowman Chrome or Topps Chrome.

You get one guess per post.

The final? hint is that the player is an A's pitcher, which means it has to be Sean Doolittle or Tommy Milone.

Good luck!
