• Hisashi Iwakuma and Joe Saunders will throw their second batting practice sessions on Saturday, and they will then take two to three days off before starting Cactus League games, according to Willis. Jon Garland and Jeremy Bonderman, both coming off arm issues, threw their second batting practices on Friday and will move into the Cactus League rotation at the start of the coming week.
• Right-hander Brandon Maurer, who is ranked as the Mariners' 10th top prospect, has been held out the past two days after taking a line drive off his shin during batting practice earlier this week.
"He was fine and threw his second BP with no problem," Willis said, "but we're going to have a bullpen [session] with him [Saturday] and he'll pitch on Monday. It'll just allow that to calm down a little. No reason to rush him out there."
• Jack Donahue, a 17-year-old senior at Juanita High School in Kirkland, Wash., attended Friday's workout as a Make-A-Wish participant. After meeting many of the Mariners players -- including Hernandez - Donahue got to hang out with Kyle Seager in the clubhouse at a locker with his name on it as the players prepared for the afternoon's game with the Padres.
