Mangum is out of the lineup for Monday's game against the Yankees.
The switch-hitting Mangum has been much more effective against right-handers (104 wRC+) than lefties (83 wRC+) over his first two big-league seasons, so he'll hit the bench Monday while the Yankees send southpaw Ryan Weathers to the bump. With Mangum taking a seat, Billy Cook will receive the start in center field and will bat ninth.
