The ranking of baseball's top prospects is done by MLBPipeline.com Draft and prospect experts Jonathan Mayo, Jim Callis and Mike Rosenbaum, who compile input from industry sources, including scouts and scouting directors. It is based on analysis of players' skill sets, upsides, proximity to the Majors and potential immediate impact to their teams. Only players with rookie status are eligible for the list. Players who were at least 23 years old when they signed and played in leagues deemed to be professional (Japan, Korea, Taiwan, Cuba) are not eligible.
Infielder Christian Arroyo (No. 1) and outfielder Austin Slater (No. 6) received significant playing time with the Giants earlier this season and might still be with them if they weren't injured. Arroyo has endured wrist and hand ailments; Slater pulled a groin muscle. Infielder-outfielder Ryder Jones (No. 14) is another young player who can call himself a Giants alumnus.
Two prospects are currently on the active 25-man roster: right-hander Kyle Crick (No. 17) and infielder Miguel Gomez (No. 23). Crick, formerly a starter, has found a home in the bullpen. Gomez has appeared in 11 games, starting two at second base.
San Francisco's first three selections in last month's Draft have made immediate impressions. Outfielder Heliot Ramos, the Giants' No. 1 pick, made his debut in the Top 30 at No. 4. Third baseman Jacob Gonzalez, the club's second-round choice, is No. 15, while left-hander Seth Corry, the Giants' third-round pick, is No. 13. All three are playing for the Giants' Rookie-level Arizona League affiliate.
Right-hander Tyler Beede, previously ranked 73rd in the overall Top 100, dropped off the list. He's ranked third in the organization's Top 30. Arroyo claimed the Giants' lone Top 100 ranking, checking in at 68th.
Arroyo also replaced Beede as the Giants' No. 1-rated prospect. Ranked No. 2 is Sacramento first baseman-outfielder Chris Shaw, considered the organization's top power-hitting prospect.
