Shifts are the best or worst thing in baseball, depending on which side you're on. They're great when your favorite team uses them, but less so when they stop your favorite team from getting on base. Regardless, they're a useful weapon for teams to employ against batters who routinely hit to a certain area.

[ Join a Yahoo Daily Fantasy Baseball contest now ] In the bottom of the eighth inning, the Padres decided to try an outfield shift against Giants third baseman Matt Duffy. They moved center fielder John Jay into right center field, moved right fielder Matt Kemp into far right field, and had left fielder Melvin Upton Jr. move to left center. If you're wondering who is actually covering center in this setup, that's a good question. And the answer is: no one. Center field was completely empty.
