Donald Arthur “Don” Mattingly (April 20, 1961-) holds the single season record for grand slams (6), which he set in 1987, despite having never hit one prior to, nor after, his record setting year. The New York Yankees took Don in the 19th round of the 1979 MLB June Amateur Draft and he debuted in the fall of 1982. Though the Yankees were notorious for leaving players to flounder in the minors or use minor leaguers as trade bait to attract bigger fish, Don flashed power at the plate and a superb glove at first base earning him a permanent spot in the everyday lineup. Donnie Baseball, as he was affectionately known, led the American League once in RBI, slugging percentage, and batting average, twice in hits and total bases, and three times in doubles. He was a six-time AL All-Star selection, won three Silver Sluggers and won nine AL Gold Gloves at first base. Mattingly spent his entire career in Yankee pinstripes (1982-1995) and enjoyed his best year one year after he was named the 1985 American League’s Most Valuable Player when he led the league in plate appearances (742), hits (238), doubles (53), slugging percentage (.573) and total bases (388). He also batted .352 with 31 home runs and 113 RBI. Mattingly’s prowess at the plate was only surpassed by his extraordinary skill at first as he posted a career .996 fielding percentage with 14,270 putouts, 1,121 assists, 1,504 double plays and only 68 errors in 15,459 chances. Don Mattingly batted .307 with 2,153 hits including 442 doubles and 222 home runs, scored 1,007 runs and drove in 1,099 RBI. Following his plying days, Mattingly worked under legendary Yankees manager Joe Torre, following him to the Los Angeles Dodgers and eventually succeeding him as the Dodgers manager from 201-2015. He took over the helm of the Miami Marlins in 2016.
