The A's offense has really struggled the last 4 games:
Record 1-3 Runs 6 AVG .170 HR 2 Walks 15 Strikeouts 53 4 Runs in each of previous 6 games (52 total)

A huge missing piece the last 4 games has been Coco Crisp.

Games 18 AVG .342 HR 3 Doubles 3 Triples 2 RBI 8 Runs 11 A's 16-2 Record (3-3 without Coco)

Really hitting the skids has been Josh Reddick and Seth Smith:
