Right-hander Nathan Karns is set to make his Mariners debut Saturday with a start against the visiting A's, who will counter with veteran left-hander Rich Hill at Safeco Field.
Karns was acquired by trade from the Rays during the offseason, after he went 7-5 with a 3.67 ERA for Tampa Bay last year. He's faced the A's just once, taking the loss while allowing two runs on seven hits across 5 2/3 innings on May 23 last season.
Saturday will mark the first time the righty has pitched at Safeco Field.
"I've been here, but never played here yet, so I'm excited," Karns said. "I'm really excited for my turn. I'll definitely be enjoying it and looking around [Friday], then [Saturday] it's all business."
Things to know
• Hill, signed by the A's as a free agent to a one-year, $6 million deal in November, struggled in his Oakland debut, lasting just 2 2/3 innings and allowing four runs (two earned) on three hits in a loss against the White Sox on Monday in place of scheduled Opening Day starter Sonny Gray, who had the flu.
• Hill is 2-0 with a 1.86 ERA in nine career appearances, but just two starts, against Seattle.
• Facing back-to-back left-handed starters to begin the series, Mariners manager Scott Servais had Nelson Cruz in right field and Franklin Gutierrez at designated hitter in the series opener but plans to flip those two Saturday.
