PHILADELPHIA -- April has never been a good month for Marlins slugger Giancarlo Stanton.
Not this April. Stanton is thriving at the plate, though he went hitless in four at-bats Sunday.
Entering the day, Stanton led the majors with 16 RBI and, with four home runs, was one behind Pittsburgh’s Pedro Alvarez and the Giants’ Brandon Belt for the league lead.
Until now, Stanton had never driven in more than nine runs in any April.
The Marlins’ team record for most RBI in April — 30 — was set in 1997 by Moises Alou.
• According to ESPN Stats and Information, Stanton has now hit two of the three longest home runs in the majors this season.
Stanton’s tape-measure homer Saturday, which landed on the outfield concourse known at Citizens Bank Park as “Ashburn Alley,” was measured at 469 feet by the ESPN stats crew.
That makes it the third-longest home run of the season.
Stanton hit the longest — 484 feet — at Marlins Park on April 4. Atlanta’s Justin Upton hit a 477-foot shot on Thursday.
The Marlins are dealing with yet another injury to one of their second basemen. Derek Dietrich missed his second game in a row Sunday for what he said were back spasms.
Dietrich doesn’t think he will be out for long.
“I’m feeling improvement [Sunday], so I’m available off the bench and will probably get back in there [Monday],” Dietrich said before Sunday’s game.
The Marlins are already without Rafael Furcal, their projected Opening Day second baseman, and backup Ed Lucas. Both are on the disabled list.
Dietrich said he thinks he injured his back while making a relay throw on Jimmy Rollins’ triple in Friday’s game.
“When I threw it in, my back started feeling a little weird,” Dietrich said. “Then I woke up [Saturday] and I was tight. We just erred on the side of caution, got a lot of treatment. I’m feeling a lot better [Sunday].”
