Back to some Replay League history...
All of the achievements start in 1948, so I usually have no record before then. But as far as I know, no 4 home run games happened before then. These are the men that have hit 4 HR in a single game, in chronological order.
Hank Aaron, 1956
The Hammer was quite unlike his real life career. He led the league in HR once, with a career high 33. He was a good, but not great hitter. He never won an MVP, nor did he ever deserve to. But, he did win 12 Gold Gloves. He is in the HOF because of his defense. Despite all this, he somehow managed to be the first 4 home run guy.
Curt Blefary, 1971
Blefary, on the other hand, was a monster. He had two more 3 HR games in 1971, something nobody else accomplished that year even once. Given that he led the league in HR eight straight years, this is not surprising at all.
Len Matuszek, 1981
I don’t know exactly what to say about this. Matuszek had 83 career home runs and 6 career WAR. The 4 HR game was on April 11, so that would have been just a week into his rookie season. This is the strange one for sure.
Bo Jackson, 1987
You already know about another guy that hit some homers for the 1987 Mariners. Bo was no slouch, hitting 44 himself that year, in his sophomore season. The Mariners hit 285 HR that year. McGwire hit 84 of course, but then Dan Pasqua hit 48. Bo had 44 as I just said, and coming in fourth on his own team was Darren Daulton with 42. That’s 218 HR from four guys. I don’t think that ever happened in real life!
Anyways, Bo Jackson was sadly (for him) traded after the 1987 season to the Astros, for Bill Wegman and Chuck Jackson. After five mostly disappointing seasons in Houston, the Marlins picked him up in the 1993 expansion draft. He has mostly been a bench player since his one big season. Sorry to all you Bo fans!
Mickey Tettleton, 1988
One year later, Mickey Tettleton joins the club. 1988 would be the third of three consecutive seasons where Tettleton would win the NL MVP award. His combination of homers and walks have made him the Mickey Mantle of catchers. He deserved all three MVPs, he hit 50+ HRs in 1986 and 1987, and has generally hit the crap out of the ball for his entire career.
As time went on, Tettleton settled down as merely a perennial all-star. Things got a little tricky in San Diego however, when they drafted Ivan Rodriguez a few years back, and he is really good too. They split time, with Tettleton playing about 2/3 of the time, until Rodriguez was traded last year. Tettleton has slowed down but is still hitting HRs and walking enough to be an above average player. He had 3.7 WAR last year, at age 36. He plays solid defense too - he even won a gold glove in 1995. He will reach 400 HR this year, and with more than 80 WAR to his credit, he will sail into the Hall of Fame when his time comes. He was the premier catcher of his era.
That’s it - just those five games. A much more rare event than in real life for whatever reason. With all of the offense of the 1990's. it hasn't happened since 1988.
