San francisco >> The Giants haven’t been mathematically eliminated from the postseason, but they sent their strongest signal yet that they’re turning the page to next season.

San Francisco, which, per FanGraphs, had a 0.3% chance of making the playoffs before starting its three-game series at home against Arizona, recalled top prospects Marco Luciano and Luis Matos on Tuesday. Unless the Giants make a miracle playoff push, both players will have a chance to play regularly in September as the Giants run out the clock on the season.

“They’re here for a reason now, so they’re going to get some at-bats,” Giants manager Bob Melvin said. “But it’s also looking at how things go next year. We’re looking toward next year and what the roster construction’s going to look like then. These are some of our best prospects, and they’re going to get a bit of a look right now.”

In promoting Luciano and Matos — San Francisco’s second- and seventh-ranked prospects from their 2023 MLB Pipeline list — the Giants optioned catcher Blake Sabol and infielder Casey Schmitt.

Melvin noted that there’s no asterisk beside the Giants’ name in the standings, so anything is possible. San Francisco could make up ground in the next two weeks against the National League playoff-contending Diamondbacks, Brewers, and Padres, but they haven’t shown the ability to win consistently. Just recently, they went a combined 4-4 in games against the sub-.500 Athletics, Marlins and White Sox.

So, realistically, September will be an opportunity to get a closer look at some young Giants who have been buried in the organizational depth chart.

Luciano, the former top prospect in the farm system, took pregame grounders at second base — where he’s most likely to get consistent playing time. Luciano committed five errors in nine games with the Giants at shortstop, his primary position, and has since been leapfrogged in the pecking order there by Tyler Fitzgerald.

“Fitzy’s doing a nice job at short,” Melvin said. “So that’s where the other spot is. And I think he’s played 20 or 21 (minor league) games at second base. So, middle infield, that’s kind of where he’s been. It’s going to feel a little different for him, even though he’s played some games there. But the bat is good, and with consistent at-bats, hopefully, he gets on a run offensively, and that makes the defense come a little easier for you, too.”

Luciano has appeared in 17 games for the Giants this year, hitting .289 with a .733 OPS. Just 22 years old, Luciano has potential as a power hitter, but finding a position he can stick at is the biggest question with his development.

At second base, Luciano’s path to regular playing time is cleaner than Matos’s. In the outfield, the Giants have Heliot Ramos, Mike Yastrzemski, Michael Conforto, Grant McCray, Jerar Encarnacion, and Mark Canha as options.

“We have six outfielders now, and at some time, we’re going to have to rotate all these guys in,” Melvin said. “You also have the DH spot, so you could have four in a particular day, but probably a little more of a rotation as far as the outfielders go.”

In 40 MLB games this season, Matos has struggled at the plate, slashing .217/.238/.333. Plate discipline is something to watch with him, as he has struck out 18 times compared to four walks. Matos has made much better swing decisions in the minors, and the power (14 home runs in 75 games) has followed.
