There are many reasons why the A's are a laughing stock this season. Lack of offense certainly is one factor. Oakland ranks last in runs, batting average and OPS. 

The A's were blanked, 4-0, by Miami's Edward Cabrera on Friday. Now Oakland draws another excellent Marlins pitching prospect in 6-foot-8 righthander Eury Perez, who has a 2.84 ERA in four starts while averaging a strikeout per inning. He faces an Oakland lineup that is averaging a puny two runs in its last 15 games. 

The A's have terrible pitching, but Luis Medina has been semi-respectable giving up three earned runs in three of his last four starts while averaging nearly six innings during this span. Those starts have come against better offensive teams than the Marlins in the Astros, Mariners, Diamondbacks and Rangers. The Marlins have scored the third-fewest runs in the majors. 

The kicker is Doug Eddings is the home plate umpire. He's a top Under ump. The Under is 47-34 (58 percent) the past four years Eddings has been behind the plate.
