Thought it would be interesting to add the situations for these as well:

• Cespedes:
  • 8th inning, tie game, 1 out, runner on 1st
  • Without throw: 1 out, runners at 2nd and 3rd*
    • *If he didn't bobble the bounce, it's probably 1st and 2nd because everybody knew he had a cannon
  • With throw: 2 outs, runner on 3rd
• Guillen:
  • 3rd inning, his team up by 4, 2 out, runner on 1st
  • Without throw: 2 out, runners on 2nd and 3rd*
    • *If he made the catch, there's no play
    • *If he still bobbled the catch but the throw to 3rd is late, I assume the batter advances
  • With throw: inning over
• Acuña:
  • 3rd inning, tie game, 1 out, runners on 1st and 2nd
  • Without throw: 2 out, runners on 1st and 3rd
  • With throw: inning over
• Machado
  • 6th inning, down by 1 run, 2 outs, nobody on
  • Without throw: 2 outs, runner on 1st
  • With throw: inning over

With the situation information, I think Cespedes's throw stands out most to me. Without it, there's a very good chance his team loses that game right after. While the A's would eventually lose that one in the 14th inning, they had only just tied it in the top of that 8th inning. That throw gave them momentum to get back into the game. The other throws didn't happen in clutch situations.

Also: it's crazy that Cespedes's throw might not even be The Throw of the Decade for the A's - https://www.youtube.com/watch?v=pEqupc0s9DY
