Bryan Woo lost to the Angels after giving up five runs — four earned — in 5 1/3 innings Thursday.

The Mariners could have lifted Woo with a 4-3 lead after five, allowing him to finish with a 3.91 ERA, but after two more earned runs in the sixth, he ends the season with a 4.01 ERA. It’s something that could pay off for the team with Woo eligible for arbitration for the first time. Not only did his ERA eclipse a round number, but he also took his 10th loss, matching his total from the previous two seasons combined.
