Even wilder? Miller did it throwing nothing but his slider - three outs from nine strikes on nine sliders.
It gets even crazier when you realize that the first time a Padres pitcher (Brian Lawrence) threw an immaculate inning was on June 12, 2002...also against the Orioles
Unfortunately for Miller and the Padres, the Orioles took the matchup in 7-5 win to complete the series sweep.
Miller was traded to the Padres at this year's deadline and has been outright phenomenal. Heading into Wednesday's matchup, Miller had posted a ridiculously impressive 1.64 earned run average in 11 games for his new National League squad.
Now, in his 12 innings of work for the Padres, Miller has posted 22 strikeouts to just five walks in 12 innings of work.
San Diego now holds the second spot in the NL Wild Card race and are just three games behind their NL West rival Los Angeles Dodgers for the division lead.
They'll be traveling to Colorado to face the Rockies in a three-game series that starts on Friday, September 5th. Meanwhile, the O's are heading back home to Baltimore to host the Dodgers in a three-game series on the same day.
