Remember the Giants’ Opening Day lineup featuring the outfield of Connor Joe, Steven Duggar and Michael Reed? Yeah, that didn’t work out so well.

It was the latest chapter in the ongoing story of the dearth of outfielders throughout the Giants’ system, give or take a Heliot Ramos.

Well, the Giants acquired Kevin Pillar in April and added Mike Yastrzemski in May, and Alex Dickerson showed up in June and was wildly productive through July.

Suddenly, thanks to trades for those three players, the Giants’ outfield wasn’t a weak link anymore. Further encouraging developments played out during the minor-league season and draft, and suddenly the organization is far deeper in outfielders, including several who came through the international ranks.

Alexander Canario: The 19-year-old from the Dominican Republic had an eye-opening third season in the Giants’ system, hitting a combined .318 with a .377 on-base percentage and .623 slugging percentage in the Arizona rookie league and short-season Salem-Keizer.

Canario hit 16 home runs and 20 doubles in 59 games. He had 11 homers combined his first two seasons.

“He can play center. He has bat speed and power. He’s a good runner. He’s got skills,” director of player development Kyle Haines said. “He’s a high upside player with a lot of ability, and now we have to turn his potential into performance.”

Franklin Labour: The 21-year-old didn’t show much power his first three seasons in the system but slugged 14 homers in 41 games this year at Salem-Keizer to accompany his .307 average and 1.030 OPS.

“I don’t know if he’s the raw slugger that hit 14 homers in 41 games, but he’s got doubles and homers power when needed,” Haines said. “He’s got more of a thicker body (6-foot-1, 190 pounds), and he’ll get stronger and thicker as he ages. But he can hit.”

The power increase (he had seven homers in his first three seasons) could be attributed to a better understanding of the strike zone and the simple fact he’s getting stronger. When he was promoted to Class A Augusta, however, he homered once in 31 games. So he’ll need constant adjustments as he climbs the minor-league ladder.

Jairo Pomares: Anyone hitting .368 at any professional level will get attention. The lefty-swinging Pomares wowed ’em in rookie ball, playing for the Giants’ Black team — they also have an Orange team — and earning an August promotion to Salem-Keizer.

Pomares, 19, signed for $975,000 out of Cuba in 2018 and debuted professionally this year. He’s a good contact hitter who doesn’t strike out much and goes to all fields, and his advanced bat was a reason he didn’t start his pro career in the Dominican Summer League.

The Giants project him as a corner outfielder who will develop more power.

“The bat’s got to carry him, but he’s got good demeanor to him,” Haines said. “We’re excited to see how he develops. Game strategy is going to be something that will determine how high up the chain he can hit.”

Hunter Bishop: The 10th overall pick in June’s draft, Bishop got his first taste of pro ball and hit .229 in 32 games, mostly at Salem-Keizer. He walked a bunch, which explains his impressive .438 OBP, and showed good speed. His best initial impression was his defense.

“He played a great center field,” Haines said. “He’s a better center fielder than we thought we were getting. He can run it down and move like a free safety would in football. We have a well-rounded hitter with power who can play center field every day.”

Bishop, 21, hit five homers in 105 at-bats, but more power is expected.

Asked if Bishop will move quickly through the ranks, Haines said, “He’s going to move as well as his bat allows him to move. It’s kind of a TBA. He played in the Pac-12 and was challenged a lot. I wouldn’t be surprised if he has a good year next year and has multiple stops.”

Heliot Ramos: As the Giants’ best prospect behind catcher Joey Bart, Ramos is further along than all of the above. At 19, he nicely handled California League pitchers at San Jose, hitting .306 with 13 homers and 18 doubles in 77 games and was moved up to Double-A Richmond, where he hit .242 in 25 games.

Ramos is among a fleet of promising outfielders in the system. It’s too early to predict whether any will become the Giants’ first homegrown outfielder to make an All-Star team since 1986 (Chili Davis), but it’s a start.
