Buster Posey and Brandon Belt had an on-field tiff Saturday night - MLB

The Giants beat the Cardinals on Saturday night, but there was some grumpiness between a couple of Giants players all the same.

As Hank Shulman reports, late in the 13-inning game Fox TV cameras caught catcher Buster Posey yelling at first baseman Belt after Stephen Piscotty of the Cardinals stole second base. Then, after the final out, there was a brief, cold stare down between the teammates. The issue would appear to be Posey being upset with Belt for not holding Piscotty close at first base and then Belt being upset with Posey for calling him out in front of God and the fans and the TV cameras and everyone.

Neither Posey nor Belt would talk about it to reporters afterwards or on Sunday, saying the matter was between them and that they’d deal with it privately. Which is a smart move.

Of course, if Posey heeded that advice beforehand and took up his dissatisfaction with Belt in private, the reporters wouldn’t have even known about it in the first place.

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.
