What began as an exercise in hitting breaking balls Wednesday evolved into Stanton and Bonds, baseball's all-time home run king, teeing off for homers on the back fields at the Roger Dean Stadium.
Stanton says he hit three homers and Bonds finished with four. It wasn't exactly a home run hitting contest, but Stanton, 26, and Bonds, 51, held their own.
"Hit another 50-year-old out there, and he'd probably snap his back in half," Stanton said. "Either way, that was probably one of the coolest things we've done because we all had a good time while we were getting our work in.
"Everyone seemed to gravitate toward that field by the time we were done, so it was really cool."
Marlins manager Don Mattingly, a former AL batting champ, said he won't take part in any drills.
"I know better," Mattingly said. "I had one back surgery, I don't want another one."
Stanton was among five Marlins, most not scheduled to play on Wednesday, who went to the practice fields following batting practice for a little extra work.
To even the teams, assistant hitting coach Frank Menechino, who worked the pitching machine, suggested Bonds fill out Stanton's team. Bonds, who hit 762 career homers in his 22-year playing career, obliged.
The goal of the workout was to score as many runs as possible before hitting three balls that would generally be considered outs. Yelich and Stanton stressed it was not a home run hitting contest.
"It was just to see who could score runs, and a homer scored you a run, and it kind of turned into that," Yelich said.
It's not the first time Bonds, who declined to comment, stepped into a drill with the players. But those instances usually happened out of public view.
"It was the first time anyone else has seen it," Yelich said. "He's hit with us before, but usually in the cage or something like that."
