Bash Brothers

Both prolific home run hitters, the two were teammates in Major League Baseball (MLB) for seven seasons with the Oakland Athletics, helping the team win a World Series title in 1989.

[2] McGwire played college baseball for the USC Trojans, and set a school record with 32 home runs in his junior year.

[3] The two combined for over 200 home runs as Oakland captured the AL pennant in three consecutive seasons from 1988 through 1990, winning the World Series in 1989.

[5][6][7] In 1988, Canseco was unanimously voted the AL Most Valuable Player after batting .307 and leading the majors with 42 home runs and 124 RBI.

He also added 40 stolen bases (SB), which combined with his home run total made him the first major leaguer to ever reach the 40–40 club.

[13] The A's marketing department teamed with local San Jose television station KICU-TV to make a song and complementary music video to the tune of "Monster Mash", the 1962 hit by Bobby "Boris" Pickett.

[14][15] The "Monster Bash" video debuted on the Coliseum’s large Mitsubishi DiamondVision during the A's homestand against the Chicago White Sox on April 15–17, but was temporarily shelved after Oakland was swept in the three-game series.

[15] However, the A's released the song to local radio stations, and it ended up on the playlists of almost a dozen of them, whose formats varied from top 40, oldies, new age, and even news/talk.

[16] While the industry standard at the time was to show action shots of athletes, Costacos Brothers gave their subjects amusing personas matched with catchy slogans.

[11] Canseco and McGwire were made to look like a bigger and meaner version of The Blues Brothers who were also partial to some yellow in their attire—yellow being an A's team color along with green.

[16] Due to the frequency and distance of their home runs, the Bash Brothers were a popular attraction in every American League city.

[27] However, McGwire's contract was expiring at the end of the season,[27] and he was traded mid-season to the St. Louis Cardinals for pitchers T. J. Mathews, Eric Ludwick, and Blake Stein.

[38] In October against Boston during the 1988 American League Championship Series, Red Sox fans at Fenway Park loudly chanted "Ster-roids!

[39] During his home run record chase in 1998, McGwire was spotted with a bottle of androstenedione in his locker by Steve Wilstein of the Associated Press, which he eventually admitted to using.

"[46] In their first home game after its release, the A's tweeted at The Lonely Island about The Unauthorized Bash Brothers Experience and played one of its tracks, "Oakland Nights", at the Coliseum.
