OAKLAND -- Fautino De Los Santos' numbers are slightly puzzling, and perhaps more so troubling.

The A's right-hander has not allowed a run in five of his six games this season. But, he has yet to retire a batter in any of his past three appearances -- a first in A's history since at least 1918. Overall, the reliever's opponents have a .412 batting average against him and a .500 on-base percentage.

"It's been a little bit of a struggle for him," manager Bob Melvin admitted on Tuesday. "He's trying to find a bit of a rhythm for himself. Just a little bit of a rut, and it's how you handle the struggles and how you get past them. The past three games haven't been his best."

It's possible that his next game will come at Triple-A Sacramento. The A's are prepared to make a roster move on Wednesday, when starter Jarrod Parker is officially promoted. It's all but certain one of their eight relievers will be sent out.

Given his minimal experience, lefty Pedro Figueroa would normally be a strong possibility -- except for the fact he has not allowed a run in two innings with the A's. That stretch follows a string of seven scoreless innings for Sacramento and seven more during the spring.
