Watch: Giancarlo Stanton clubs his 40th home run - MLB

Giancarlo Stanton unleashed his 40th home run of the season on Friday night, a new career high mark and about two home runs shy of a new franchise record, too. The milestone blast came in the sixth inning of the Marlins’ 6-3 showstopper against the Rockies, kicking off a late-game rally that shifted Colorado to a mere half-game lead in the National League wild card standings.

Per Statcast, Stanton muscled the ball an estimated 433 feet to center field. The solo shot marked his seventh homer in his last 10 games; with just two more, he’ll tie Gary Sheffield for most single-season home runs in the Marlins’ 25-year history. Sheffield hit the mark in 1996 on a fifth-inning pitch off of the Expos’ Mark Leiter.

Stanton wasn’t the only one to collect a milestone hit during the Marlins’ win, either. Nolan Arenado took Jose Urena deep with a two-run shot in the third inning, plating Charlie Blackmon for his 100th RBI of the season. He’s the first player to reach 100 RBI in 2017 and has now collected at least 100 RBI in each of his last three seasons.

The Marlins completed their rally with a J.T. Realmuto sac fly, Derek Dietrich RBI single and Tomas Telis two-run triple, earning their 54th win of the year and scooting the Rockies a full 16.5 games back of the NL West-leading Dodgers. They currently rank second in the NL East, but sit 14.5 games behind the Nationals and an even 10 games back of a wild card berth.

PITTSBURGH — The New York Mets will have to dig out of an early-season hole without star first baseman Pete Alonso.

The leading home run hitter in the majors will miss three-to-four weeks with a bone bruise and a sprain in his left wrist.

The Mets placed Alonso on the 10-day injured list Friday, retroactive to June 8. Alonso was hit in the wrist by a 96 mph fastball from Charlie Morton in the first inning of a 7-5 loss to Atlanta on Wednesday.

Alonso traveled to New York for testing on Thursday. X-rays revealed no broken bones, but the Mets will be missing one of the premier power hitters in the game as they try to work their way back into contention in the NL East.

“We got better news than it could have been,” New York manager Buck Showalter said. “So we take that as a positive. It could have been worse.”

New York had lost six straight heading into a three-game series at Pittsburgh that began Friday. Mark Canha started at first for the Mets in the opener. Mark Vientos could also be an option, though Showalter said the coaching staff may have to use its “imagination” in thinking of ways to get by without Alonso.

“I’m not going to say someone has to step up and all that stuff,” Showalter said. “You’ve just got to be who you are.”

Even with Alonso in the lineup, the Mets have struggled to score consistently. New York is 16th in the majors in runs scored.

The team also said Friday that reliever Edwin Uceta had surgery to repair a torn meniscus in his left knee. Uceta initially went on the IL in April with what the team called a sprained left ankle. He is expected to be out for at least an additional eight weeks.

New York recalled infielder Luis Guillorme and left-handed reliever Zach Muckenhirn from Triple-A Syracuse. The Mets sent catcher Tomás Nido to Triple-A and designated reliever Stephen Nogosek for assignment.

Nogosek is 0-1 with a 5.63 ERA in 13 games this season.
