Diaz (hamstring) went 2-for-4 in Sunday's 11-3 loss to the Rangers.
Diaz missed just over two weeks with a hamstring strain. The first five hitters in the Athletics' lineup went a combined 0-for-19 on Sunday, but Diaz provided some solid batting from the No. 7 spot in the order. The versatile 32-year-old is slashing a meager .169/.237/.225 with one home run, six RBI, seven runs scored, a stolen base and two doubles through 97 plate appearances. Despite his lackluster numbers, he should be able to find fairly steady playing time.
