Giancarlo Stanton has gone cold on the road.
Stanton, who once awed crowds from Colorado to California with gargantuan blasts, can’t explain where the firepower has gone when the Marlins are away from home.
“I have no clue,” Stanton said. “It’s unexplainable.”
Statistically, it’s dumbfounding. Of the 210 major-league players with at least 150 plate appearances on the road this season, Stanton’s .301 slugging percentage ranks 199th. That contrasts to his home slugging percentage of .611, which ranks fifth in the majors.
He has belted only three home runs on the road — vs. 10 at home — and two of those came in a June 17 game in Arizona. He has a .302 batting average at home but is hitting only .182 on the road — the fourth-worst figure in the majors. He has hit only one home run over his past 24 road games entering Monday.
“Usually it’s the opposite,” Stanton said of his road success.
Stanton has gone 3 for 20 with only one RBI on the current road trip and was benched for one game in Atlanta with the belief the mental break would do him some good.
“I haven’t really been right all year, so those numbers are just coincidence,” Stanton said of his road-home differential.
Visit from Boles
Former Marlins manager John Boles paid a surprise visit to Mike Redmond’s office before Monday’s game. Boles, who is now senior adviser to the general manager for the Royals, once managed Redmond on the Marlins.
“One of the things I learned the most from Bolesy was he was always honest,” Redmond said. “He was a straight shooter. He told you exactly where you stood. It’s one of the things I try to do as manager, is I try to be honest with these guys. I learned that from him.”
Boles managed the Marlins in 1996 and again from 1999-2001, compiling an overall record of 205-285.
Boles noted the similarities between his Marlins teams and Redmond’s. Both were built around talented young pitching but lacked offense. Pitchers such as A.J. Burnett, Ryan Dempster and Brad Penny were just starting out when Boles was in charge of the helm for the Marlins.
“Sounds like [they] have some good young arms,” Boles said. “We didn’t hit much, either. It’s just a matter of time. You’ve got to go through the growing pains. Once that happens, everything’s roses.”
While the Marlins last played in Kansas City in 2007, Kauffman Stadium isn’t foreign to rookies Jose Fernandez and Christian Yelich. Both played there in the 2012 Futures Game.
Fernandez pitched one inning, striking out two, and Yelich singled in two at-bats. The two were teammates at Single A Jupiter at the time.
“I thought it would be nice to come back here someday,” Yelich said of his thoughts at the time. “And here we are.”
