17. C.J. Hinojosa
This University of Texas product may have been the most talked about position player in the Giants' organization during minor league spring training in 2016. He began to live up to that hype quickly, leading the California League in batting average through the first 30 games with the San Jose Giants. C.J. Hinojosa wont impress you with raw power or quick bat speed, but rather good hand-eye, strong forearms, and the ability to go to all fields with good extension. Defensively, Hinojosa initially looked lackluster at shortstop, averaging an error every sixth game or so in San Jose, but has improved drastically in the years since. Hinojosa began to work as a utility man with Richmond in 2017, logging his first innings at second and third base as a pro.
18. Chase Johnson
His breakout performance was a 14-strikeout, complete-game shutout in his final 2015 start in San Jose — a game where his fastball topped at 98. The former Cal Poly closer, Chase Johnson has worked as a pro on refining his wind-up while being groomed into a starter. He had been taking the mound as one since debuting from the third round in 2013, but the Giants moved him back into the bullpen in late May of 2016. After 18 starts a year before produced a 2.92 ERA and strikeout-per-inning type stuff, Johnson was promoted to Richmond where Double-A was a bit of a grind. Now in Sacramento, before sadly having season-ending Tommy John surgery, Johnson returned from 92-93 to mid-to-upper 90s, along with a solid secondary offering in a slider, plus a box changeup he throws to lefties.
19. Ryder Jones
Ryder Jones, still just 23, made his Triple-A debut alongside draft mate Christian Arroyo in 2017. At no point had Jones's numbers ever been impressive, until he put on a River Cats uniform. Aside from his rookie season in the AZL, Jones had not eclipsed more than 90 in wRC+ and had a career OPS of .680 — both below average marks. But one could look at his 2016 campaign and see the positives. Take for example his 15.4 K%, which is improved from 18.5% in 2015 and 22.1% in 2014. Or his Fall League performance just months ago, where Jones slashed .302/.380/.429 against some of the best pitching prospects in baseball. Jones and his raw power shined in the Pacific Coast League, posting a .254 ISO along with a 11.4 BB% before being called up to San Francisco.
20. Melvin Adon
There was a good amount of hype surrounding Melvin Adon at the beginning of the 2016 season, and for good reason. Talk of a 100-mph starter is always exciting, and though he hadn't been posting triple digits regularly, if at all, in 2016 with the Salem-Keizer Volcanoes, there's certainly a lot to like about this raw arm. Fangraphs had him 94-97 in May with a mid-80s slider, featuring some nice horizontal movement, and an upper-80s, below-average changeup. Signed as a 20-year-old in 2014, Adon skipped the Arizona League after one year in the Dominican Republic. He's a project with a ton of potential at this point, but the Giants' farm system is known for handling these situations well. The most updated info on Adon comes from Baseball America's J.J Cooper, who reported an encouraging bit about Adon's delivery becoming more simplified and still creeping around 100 mph.
