Santiago allowed four runs on three hits and three walks while striking out two over 2.2 innings in a no-decision against the Orioles on Friday.
Santiago gave up three home runs in his short stint, but a three-run sixth inning by the Angels took him off the hook for a loss. He's now failed to complete six innings in four of his last five starts, and during that stretch, his ERA has grown from 2.70 to 3.93. He'll make his next start Wednesday against the Rangers.
