Even the minor leagues have All-Star games, though with WAY less fanfare than the MLB version of course.
The Midwest League (A) game kicks off tonight at Perfect Game Field in Cedar Rapids, Iowa. First pitch should be around 4:05PM PST. The MWL is home to the Angel's affiliate Burlington Bees who are sending pitchers Grayson Long and Jaime Barria to the game. You can check out the full roster at Baseball America. It's unclear if Grayson Long can even pitch since he's been on the DL for a few weeks and I haven't been able to figure out why.
