For the first half of the season, Marco Gonzales was a pain in the neck for opposing batters.
But recently, it's a pain in his neck that's kept Gonzales sidelined.
The left-hander has missed his past two starts but threw a 35-pitch session off the mound last Friday and is expected to come off the disabled list Tuesday to start the series opener against the San Diego Padres at Safeco Field.
"I was dealing with some fatigue, some neck aches, some things I was battling through and trying to push through, hoping it would get better," Gonzales told MLB.
