Philip Humber April 21, 2012 Chicago White Sox Seattle Mariners 4 - 0

Humber became the 4th %. in the country out of Rice college by utilising the Mets in the 2004 MLB draft. he had injury subject concerns in the minors and has purely shown flashes of what became promised to be an marvelous profession. the suited game became one among those flashes, the way he pitched for the Mets in 2007 and the Astros this 3 hundred and sixty 5 days, regrettably became the different component of him. BQ: sure, it is going to likely be.

Interesting that of the 21 perfect games thrown, the first 9 spanned 88years (1880 -1968) and the last 12 has spanned only 31 years (1981-2012).
