Looks that way.
AA did his usual "I have 5 starters and expect them all to stay healthy" routine instead of loading up on depth like a normal GM would. He's paying the price for that, and not doing anything to help the pen.
The sad thing is, the offense actually is excellent, so even slightly above average pitching gets this team to the post-season. Unfortunately, they are going to finish near last in pitching, so it's .500 and the treadmill keeps on rolling along.
