The Giants don't have a bonafide closer. They do, however, have several quasi-closers who have filled that role in the past, or possibly could do so in the future.

Will Smith, Mark Melancon, Sam Dyson, Tony Watson and Reyes Moronta have combined to post a 1.82 ERA and 1.03 WHIP in 39 2/3 innings, giving San Francisco what ranks as one of the best bullpens in all of baseball. The Giants' relievers rank first overall in WAR (plus-1.6), according to FanGraphs.

With the emergence of Trevor Gott (plus-0.3) and Travis Bergen (plus-0.2), the Giants suddenly have an abundance of good-but-not-great options from both sides of the mound in the later innings.

The Atlanta Braves, however, suddenly have one fewer option, and it's a big loss. The team announced Wednesday that closer Arodys Vizcaino had season-ending shoulder surgery.

Of the Giants and Braves, one team seems significantly more likely to make a run at the postseason than the other, and it's not the one that has scored the third-fewest runs in all of baseball.

San Francisco could certainly use an influx of youth and talent into all levels of the organization. Although a potential trade for one of the Giants' aforementioned quasi-closers wouldn't net a ton in return, the Braves entered the season with the third-best farm system in the majors, according to MLB.com.

The Giants' bullpen has surpassed expectations and been a pleasant surprise, and yet, San Francisco has been below .500 since Opening Day. They're not going to contend this season, and if they're going to a year or two from now, a call to the Braves is the kind the Giants should be making.
