1. RF GIANCARLO STANTON IN 2017
Could there have been anyone else in the number one spot? It can only be RF Giancarlo Stanton back in that 2017 season. That was a season for the ages, as Miami Marlins fans were hoping that Stanton would break the single season home run record. That record was of course set in 2002 by Barry Bonds, as he hit 70 home runs.
It's important to point out, that Bonds' record comes with an asterisk. He was on steroids while setting the record. The real record was set by Roger Maris in 1961, with 61 home runs. Aaron Judge broke that record with 62 home runs in 2022. Giancarlo Stanton was actually on pace to break Maris's record at the time.
Could Giancarlo Stanton have come close in that 2017 season? Once again, as sadly with all of these seasons, the Miami Marlins did not make the playoffs that season. Stanton batted .281/.376/.631, with 59 home runs and 132 RBI, in 159 games and 597 AB. He was worth 0.4 dWAR and overall he was worth 7.9 WAR. That's a record for WAR among Miami Marlins position players in team history.
Did Giancarlo Stanton win the NL MVP award that season? YES! Stanton won the award for the only time in his career that season. Deservedly so. He was traded to the New York Yankees after the season. That trade turned out to be a blessing in disguise for the Miami Marlins, as he batted just .243/.328/.485 since the trade.
