San Francisco Giants: Who should replace Brandon Belt as leadoff hitter?

The San Francisco Giants have fallen below .500 for the first time since mid-July. It might be time to consider shaking up the batting order, starting at the top.
The leadoff spot in the batting order has been a revolving door for the San Francisco Giants this season.
Seven different players have seen their name penciled into the top spot, including Steven Duggar on Opening Day and Michael Reed for the second game of the season.
All told, the team has gotten a .245/.312/.356 line from its leadoff hitters this year, which amounts to a .667 OPS that ranks 26th in the majors.
The most recent attempt at finding a leadoff solution has been first baseman Brandon Belt.
With a .347 on-base percentage and a patient approach at the plate, it’s easy to see the logic behind giving Belt an opportunity to serve as a table-setter.
However, the results have not been pretty.
In 29 games hitting first in the lineup, Belt has put together a .237/.316/.297 line.
While Belt was never a prototypical fit for the top of the order, his on-base skills made it a worthwhile experiment. Now It’s time to make a change.
So who should be the next player to get an opportunity to spark the offense?
