Six of those nine duels this year went Under, while that was the case in seven of Seattle’s last ten games. I am going with another Under in this clash because of the starting matchup. Jeffrey Springs posted a 1.64 ERA in two starts against the Mariners, while Bryan Woo registered a 4.50 ERA in two starts against the Athletics. Back Under.
