The Giants have won three World Series and averaged 87 wins per season this decade, thanks in large part to their ability to identify and refine talent. They signed and developed their two superstars, former first-round picks Madison Bumgarner and Buster Posey, as well as All-Star infielders Brandon Belt, Brandon Crawford and Joe Panik. They're set to contend for another championship in 2017, and on many days they'll have seven homegrown players in their lineup.
San Francisco's farm system never seems to receive much acclaim but keeps churning out big leaguers. The majority of the players on our Giants Top 30 Prospects list are set to arrive at AT&T Park in the next year or two, and right-hander Tyler Beede, infielder Christian Arroyo and outfielder Steven Duggar could play significant roles. There's plenty of bullpen help on the way, with Joan Gregorio and Steven Okert the most likely candidates to contribute in 2017.

:: Team Top 30 Prospects lists ::
The Giants draft consistently well, and their 2016 crop included a pair of potential outfield regulars in Bryan Reynolds (second round, their top choice) and Heath Quinn (third round) and a pair of high-risk, high-reward pitchers in Matt Krook (fourth round) and Garrett Williams (seventh round). They do good work internationally too, and sweet-swinging outfielder Sandro Fabian and flamethrowing right-handers Reyes Moronta, Rodolfo Martinez and Melvin Adon -- all from the Dominican Republic -- burst onto the prospect scene in 2016.
