Even with his parents up from Orange County to watch the game and Powell eager beyond words to get out there, the combination of a lingering upper-respiratory illness and an episode with asthma he hadn’t experienced in more than 10 years put him on the shelf.

Powell was picked by the A’s in the 20th round of the 2012 draft, but his only Major League experience came early this season with Seattle: a .194 batting average (7 for 36) in 23 games.

The original, now 75 years old, went 6-foot-4 and 230 pounds, hit 339 major league home runs and won the AL Most Valuable Player award in 1970.

Now Powell is not only comfortable with his nickname, he’s eager to meet the original Boog, who operates a barbeque stand on the right field promenade at Camden Yards.
