Top ten in career and season home runs for the 16 "original" teams.

Among the 16 teams that existed in 1960 but through the 2021 season, three have the same player holding the team record for both career and season home runs, two American League (AL), one National League (NL). Before you look at the data, can you name the teams and players?

This link contains the data. The eight AL teams are listed vertically. The eight NL teams are two side by side, then vertical.

Duke Snider held both the career and season Dodger home run records alone through the previous milenium. In 2000 Gary Sheffield tied Snider for the season record. In 2001 Shawn Green hit 49, the Dodger record that stands through 2021. Two other Dodgers have exceeded 43 since 2001.

The season top ten are in ascending order by year when there is a tie. Notice Mize precedes Mays at 51 Giant home runs. And Mays precedes Bonds at 49.

Here are the team leaders for the 16 teams:

The answer to the question in the opening paragraph should be obvious:

Twins (old Senators): Killebrew
Indians: Thome
Cubs: Sosa

Harmon Killebrew dominates his team's top ten season home runs like no other: 8 of 10, including the top 6.

1	Harmon Killebrew • 1964	49	Twins
1	Harmon Killebrew • 1969	49	Twins
3	Harmon Killebrew • 1962	48	Twins
4	Harmon Killebrew • 1961	46	Twins
5	Harmon Killebrew • 1963	45	Twins
6	Harmon Killebrew • 1967	44	Twins
7	Roy Sievers • 1957	42	Twins
7	Harmon Killebrew • 1959	42	Twins
7	Brian Dozier • 2016	42	Twins
10	Harmon Killebrew • 1970	41	Twins
10	Nelson Cruz • 2019	41	Twins

Albert Belle set the Indians season record in 1995 with 50, passing Al Rosen's 43 in 1953. He then set the White Sox record in 1998 with 49, passing the 41 hit by Frank Thomas in 1993.

In his final season with the Indians, Bell's old teammate Jim Thome broke Belle's record with 52 in 2002. In 2003 with the Phillies Thome led the NL in HR with 47, one fewer than the Phillies record at the time by Mike Schmidt: 48 in 1980. Ryan Howard has since hit 58 in 2006 and then 48.

Rk	Car Player	HR	Rk	Yr Player	HR	Team
1	Mark McGwire	363	1	Jimmie Foxx • 1932	58	Athletics
2	Jimmie Foxx	302	2	Mark McGwire • 1996	52	Athletics
