Kevin Mench of the 2006 Texas Rangers did it. 1) April 21 - grand slam HR against Tampa. 2) April 22 - three run HR against Tampa. 3) April 23 - two run HR against Tampa. 4) April 24 - solo HR against Oakland. Kinda like a reverse natural ... Mench's HR streak lasted 7 games as he hit a solo, grand slam, and solo HR in each of his next three games.

He shouldn't, as the information is confidental.
