Angels pitcher Hector Santiago lasted just 4 1/3 innings Tuesday, giving up four earned runs on five hits and three walks while striking out six in his team's 5-3 loss to the Mariners.

All four runs scored upon Santiago (0-2) came in the fourth inning, with three coming on one swing by Mariners designated hitter Corey Hart. The Angels starter was removed after surrendering a one-out double in the fifth inning, having thrown 94 pitches in the outing. He'll bring a 7.71 ERA and 10:6 K:BB ratio into his matchup with the A's Monday.
