The San Francisco Giants emerge from the All-Star break with a record of 52-43, trailing the Los Angeles Dodgers by one game in the NL West. The Giants are currently tied with the Atlanta Braves for the top spot in the wild-card race.

After getting out to a great start early on, the Giants struggled mightily. At one point, they had lost 21 of 29 games.

Initially, it was the combination of poor pitching and weak hitting that hurt the team. Lately, the pitching has come around, but the offense has still been very inconsistent.

In the Giants' last 20 games, they have been shut out six times and scored just one or two runs another six times.

The Giants need an infusion of excitement and production that can help get them back on the right track.

In 2010, general manager Brian Sabean brought in Cody Ross, Pat Burrell, Javier Lopez and Ramon Ramirez to bolster the team. These additions were instrumental to the Giants making the playoffs and winning the first World Series in San Francisco history.

In 2012, Sabean added Hunter Pence and Marco Scutaro. Both pumped life into the Giants and were key players in the Giants' second world championship in San Francisco over a three-year span.

Now, in 2014, Sabean is facing a similar dilemma. The Giants are contenders but do not seem to have enough to win their division. Even a wild-card berth is not a sure thing for the Giants at this point.

In order to solidify their chances, Sabean will need to make some moves to strengthen the team. The difficulty Sabean will face is the Giants do not have a lot of prospects who are highly coveted by other clubs.

Let's take a look at five players who could make a major positive impact for the Giants.
