That's because Barry Bonds, the king of the "Splash Hit" at AT&T Park, was back in town as the Marlins' batting coach.
No, Bonds never took another shot at the San Francisco Bay behind the right field fence. But he went out of his way before each game to sign as many autographs as possible for those who supported his career.
Alas, those who weren't chatting with Bonds witnessed a piece of AT&T Park history Sunday when Marlins right fielder Giancarlo Stanton belted a batting-practice fastball over the bleachers in left field.
It was a first in the 16-year history of the stadium.
There's no water behind the bleachers in left field. Rather, Stanton's blast landed in a children's play area about 500 feet from home plate and one-hopped into the players' parking lot, where an attendant stumbled upon it.
It was a sign of good things to come for Stanton, who had gone hitless in the first two games of the series. He rebounded with a three-hit performance Sunday, including a home run to left field that landed about 100 feet short of his batting-practice blast.
It counted nonetheless, giving him 54 in his career against National League West clubs, the second-most (to Ryan Howard's 67) among guys who never played in the division.
Stanton will get a crack at improving that number when the Marlins take on the Los Angeles Dodgers in a four-game series that begins Monday.
