Countdown to Opening Day - 4: Giants' unbelievable run coming to an end

In this 30-day series, theScore's MLB editors will preview the 2015 season with an in-depth look at some of the significant numbers - statistical milestones, jersey numbers and general miscellanea - poised to pop up throughout the campaign.

Appreciate what the San Francisco Giants have done now because it's unlikely to happen again for a long time.

In an era when parity reigns supreme in Major League Baseball, the Giants have done the almost unthinkable and claimed three World Series championships in the past five seasons.

With the mantra of "just make it to October," they've taken down all 10 postseason foes they faced over the last half-decade under manager Bruce Bochy.

To truly understand the magnitude of what the team has accomplished, it's important to have some context.

Over the last 10 seasons, 12 different teams have made it to the World Series, with the Giants being the only team to have won three times.

What makes San Francisco's October magic even more impressive is the fact that they've claimed more World Series wins over their run than division titles - having reached the postseason in 2014 by way of the wild card.

But those dominant days that thundered through last fall on the arm of Madison Bumgarner appear to have gone with a whimper after a devastating offseason has Bochy's squad reeling.

For an organization that has been no stranger to adversity in years past - Buster Posey's broken leg in 2011, Melky Cabrera's PED suspension in 2012 and Matt Cain's season-ending injury in 2014 - the departures of Pablo Sandoval and Michael Morse combined with an aging rotation could mean the end to the Giants' biannual World Series streak moving forward

Despite the championship pedigree the Giants have built, the front office failed to land big-name free agents Chase Headley and Jon Lester, settling for the light-hitting Nori Aoki and Casey McGehee. 

Sandoval appeared a lock to re-sign before burning every bridge out of town, and the organization's swings and misses carried into the spring.

For a team that won rings with their pitching, the rotation's gaudy numbers from spring are a cause for concern and were a key contributor to their 11-20 record.

As expected, the offense has also struggled, ranking in the bottom third in the league in home runs, average and slugging, leading Bochy to admit the team isn't anywhere where they need to be to start the season.

While the Giants should feast on the Arizona Diamondbacks and Colorado Rockies in the division, the San Diego Padres and Los Angeles Dodgers appear head and shoulders above them in the division.

After a look at the roster, the Giants appear destined to miss the postseason in 2015, but don't forget what they've accomplished.
