Lloyd McClendon has revealed that Mariners right-hander Brandon Maurer is experiencing back problems and might remain sidelined for a week, per MLB.com.
Maurer appears to be on the outside looking in at a rotation spot. He has given up five earned runs in 4 2/3 innings this spring. He showed little as a rookie in 2013 with a 5-8 record and 6.30 ERA.
