SEATTLE – The need for another reliable right-handed setup reliever has the Seattle Mariners taking a hard look at veteran Jason Frasor, who chose to become a free agent earlier this month after clearing waivers. Frasor, 37, compiled a 1.54 ERA this season in 26 appearances for Kansas City despite suspect peripherals: 15 walks in 23 1/3 innings, which contributed to a 1.67 WHIP (walks and hits per inning pitched).
