Part of the reason for Belt's aforementioned month-to-month inconsistency this season is due to the way he has been handled over the past two seasons.
He won the first base job out of spring training last season, only to lose it after just 13 starts.
He was summoned to the big leagues after Buster Posey went down with a season-ending injury, but only as a bench player.
When he finally did get another chance to start, he got injured when he was hit by a pitch. When he was recalled for a third time, he continued to be moved in and out of the lineup for the remainder of the season.
Even though he's been the Giants' primary first baseman this season, he's started just 81 of the team's 128 games despite not missing any time due to injury. He's split time with the oft-injured Aubrey Huff (10 starts), non-prospect Brett Pill (16 starts), Pablo Sandoval (2 starts) and Posey (19 starts).
While playing Posey at first is a wise move to keep his bat in the lineup, perhaps the Giants could keep Belt in the lineup as well by moving him to left field when Posey is at first.
While the Giants have not handled Belt ideally over the past two seasons, he's ultimately responsible for his performance. It's a shame that he's only received 572 plate appearances over the last two seasons, not even a full season's worth, but he hasn't exactly forced manager Bruce Bochy's hand with his .249/.341/.402 career batting line.
In the end, there's a lot to like about Belt. He's a big guy and a good athlete. If the talent wasn't there, he wouldn't have been in the big leagues after only one season in the minors.
Even though he hasn't been handled ideally by the Giants, he's managed to produce the third-best on-base percentage and the fifth-best OPS on the team this season.
Going forward, Belt will either have to hit a lot more balls out of the ballpark or cut down on the strikeouts in order to become a more consistent performer.
He's only 24 years old, and there are no other first base prospects knocking on the door in the Giants' farm system, nor are there any great options in free agency this winter.
At first base, the Giants are either going to sink or swim with Belt. Right now, they're merely treading water.
