Monday was Labor Day and, no surprise, the Mariners continued to work on their roster.
The Mariners acquired outfielder Jacob Hannemann and right-handed pitcher Seth Frankoff through waiver claims from the Chicago Cubs prior to Monday’s series opener against Houston at Safeco Field.
While Hannemann is expected to join the big-league club prior to Tuesday's game against the Astros, Frankoff is not — at least at this point.
The Mariners cleared space on their 40-man roster for the additions by placing reliever David Phelps on the 60-day disabled list because of an impingement in his elbow and by designating reliever Zac Curtis for assignment.
