The Giants' offseason has been full of signings like Kevin Gausman, Tyson Ross and Tyler Heineman. Those aren't exactly stars. 

Farhan Zaidi, San Francisco's president of baseball operations, has been more focused on adding depth like the players mentioned above, who could turn into intriguing trade options or help in the event of a playoff run. But the Giants are building stars down on the farm. 

MLB Pipeline recently named the Giants as one of baseball's five most improved farm systems. That honor makes broadcaster Mike Krukow very, very excited for San Francisco's future. 

"This is something we haven't heard for a while," Krukow said Friday on KNBR

Krukow lauded the fact that the Giants have talented teenagers such as Marco Luciano (18) and Alexander Canario (19). Led by catcher Joey Bart, San Francisco has four prospects on MLB Pipeline's top 100: Bart, Luciano, Heliot Ramos -- who was 19 years old all last season -- and Hunter Bishop. 

"With one year of Farhan Zaidi and his system in place, now you're starting to see more prospects," Krukow said. "Prospects that are legitimate. Prospects that are everyday starters at the big league level. That is really exciting. To me, I've always felt that the strength of an organization starts with a farm system.


"To get that type of recognition early on in just a year of Farhan's tenure is pretty amazing, and I'm excited about." 

While the Giants are in a bit of a rebuild mode -- despite still having veterans like Buster Posey, Brandon Belt, Brandon Crawford, Johnny Cueto, Jeff Samardzija and more -- fans might not have to wait too long to see these budding stars. Especially Bart and Ramos. 

Both prospects likely will start the season in Triple-A Sacramento. They started last season in High Class-A San Jose and promotions to Double-A Richmond. Could they move two more levels in 2020? 

It won't be easy, but don't count them out.

The Giants also essentially bought 2019 first-round draft pick Will Wilson in a trade with the Los Angeles Angels at the MLB Winter Meetings, too. Wilson already is a top-10 prospect for the Giants. Not to mention, San Francisco owns the No. 13 overall pick in this June's draft. 

There's a chance the 2020 season tests the patience of Giants fans once again. Take a deep breath, though. Talent is on the way.
