Red Sox outfielder Mookie Betts is having an unbelievable season and he just did something that few others in the history of baseball have ever done. This is Betts' third home run during Sunday's romp over the D-Backs:

At the time, Betts went 4 for 6 with three homers, eight RBI and four runs scored in a 16-2 win. That's amazing production. It also marked the second time this season that he went deep three times, along with May 31.

How many times has a player ever had two three-homer games in a season before? This would be the 21st.

Sammy Sosa actually had three three-HR games in 2001. The following had two three-homer games in a season ( play index):

Johnny Mize (1938), Johnny Mize (1940), Ralph Kiner (1947), Ted Williams (1957), Willie Mays (1961), Willie Stargell (1971), Dave Kingman (1979), Doug DeCinces (1982), Joe Carter (1989), Cecil Fielder (1990), Geronimo Berroa (1996), Steve Finley (1997) Mark McGwire (1998), Jeff Bagwell (1999), Carlos Delgado (2001), Jeromy Burnitz (2001), Barry Bonds (2001), Aramis Ramirez (2004) and Albert Pujols (2006).

That's mostly really large men. At 5-9, 180 pounds, that's pretty impressive for Mookie.

Betts is a complete stat-sheet stuffer. On the season, he's hitting .314/.353/.562 with 34 doubles, five triples, 26 homers, 84 RBI, 91 runs and 18 stolen bases. He ranks in the top 10 in the AL in hits, doubles, triples, home runs, RBI, runs, steals, average, on-base percentage, slugging percentage, WAR, total bases, extra-base hits and times on base.

Oh, and he's only 23 years old.
