Worth noting

• Dustin Ackley went 3-for-4 with a walk and four runs scored while playing center field for Triple-A Tacoma in a 16-4 win at Colorado Springs on Wednesday. The 2009 first-round Draft pick is now hitting .400 with a .505 on-base percentage in 20 games since being sent down.

• Franklin Gutierrez was 2-for-6 with two runs scored while playing right field for Tacoma as he continued his second rehab stint. Gutierrez, out since April 23 with a strained hamstring, has batted .222 with a .390 OBP in 21 games. He's eligible to return from the 60-day disabled list on Saturday.

• Tacoma right-hander Brandon Maurer was removed from Wednesday's game after one inning due to back stiffness. Maurer had given up four hits and two runs, with his ERA now 2.41 after four starts.

• DJ Peterson, Seattle's 2013 first-round Draft pick, went 0-for-3 with a walk in his debut for Class A Everett on Wednesday. Justin Seager, the 12th-round pick and younger brother of Mariners third baseman Kyle Seager, was expected to make his first start Thursday after being sidelined by a blood infection in his wrist and arm that cropped up after he signed.
