Josh Fields struck out two in a scoreless ninth inning to earn his second save of the season on Wednesday against the A's. Chia-Jen Lo had pitched in two straight games, so skipper Bo Porter elected to call on Fields, who was enjoying the one-week anniversary of his first career blown save, a three-run fiasco against the Red Sox. Lo, who hasn't allowed a run in six appearances, remains Houston's closer, while Porter's decision on Wednesday indicates that Fields is still next in line.
