• Franklin Gutierrez increased his pregame workout to include hitting in the cage as well as playing catch on Monday as he works toward a return from the concussion he suffered June 29 when he got hit in the head with a pickoff throw.
"The plan is to get him doing a little more on the field [Tuesday] and Wednesday and see where we are on Thursday before we go to Tampa," said manager Eric Wedge. "He'll do some running in the next few days and we'll get him out taking some batting practice."
• Though Jaso has played very little against left-handed pitchers and is hitting just .048 against southpaws, he will start on Tuesday against Royals lefty Everett Teaford. The Mariners are facing three straight lefties in Kansas City and Wedge said Jaso deserves the chance to play more against southpaws. He'll also play Thursday against right-hander Luke Hochevar, while Wednesday's situation remains to be seen.
• Mariners catcher Miguel Olivo leads the American League in throwing out baserunners, having caught 16 attempted basestealers. Cleveland's Carlos Santana is second with 15.
