Giants acquire Casey McGehee from the Marlins - MLB

Update #2 (10:03 PM EST): Juan C. Rodriguez of the Sun Sentinel reports that the Marlins are receiving minor league pitchers Kendry Flores and Luis Castillo from the Giants in exchange for McGehee.

Update (7:15 PM EST): Bob Nightengale of USA TODAY confirms that McGehee is indeed headed to San Francisco. It’s unclear at the moment exactly who the Marlins are receiving in return.

The Marlins added yet another infielder on Friday afternoon, acquiring Martin Prado along with David Phelps in a trade with the Yankees. Having also inserted Dee Gordon and Michael Morse into the mix, the Fish now have a surplus of infielders, including third baseman Casey McGehee.

The Giants, now without Pablo Sandoval and having missed out on Chase Headley, are in want of a passable major leaguer to man the hot corner. Rodriguez hears that the Giants and Marlins are closing in on a trade involving McGehee that would send minor league pitching to Miami.

McGehee, 32, hit .287/.355/.357 with four home runs and 76 RBI during the 2014 season. By traditional metrics, McGehee was among the more productive hitters during the first half of last season, carrying a .321 average and 53 RBI into the All-Star break. However, McGehee’s power — once responsible for a 23-homer output in 2010 — was nonexistent and fell well below the average for third basemen.

Then again, McGehee has a pulse and can navigate his way to third base, so that means he’s in play for the Giants.

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.
