Severino had more problems with the minor league park besides the mound:
Perhaps the biggest change for players’ routines at Sutter Health Park is the clubhouse, weight rooms and training areas being disconnected from the dugout. In standard Major League stadiums, the clubhouse is typically underneath the grandstand and a short walk to and from the dugout.
But at Sutter Health Park, the clubhouse and player facilities are beyond the left field wall, meaning starters pitchers must stay in the dugout between innings. Sutter Health Park, of course, was built to house the Triple-A Sacramento River Cats and is being used temporarily by the A’s while they hope to begin construction on a new stadium in Las Vegas after they elected not to continue playing at the Oakland Coliseum when the lease expired after last season.
Severino said in other ballparks he often goes into the clubhouse or workout areas between innings to stay loose.
“If you watch every starting pitcher, you don’t see them in the dugout,” Severino said. “Usually you go inside, watch the game on TV, get on the (exercise) bike a little bit... It’s just different. Everybody’s different. For me, it’s being able to have the gym closer. If something’s happening, let me get on the bike, get my legs moving. Let me do something before I go out there.”
They've talked about Schwarber's routine during the games there, and pinch hitter's issues, then today they mentioned the warning track is much larger than typical MLB ones, so outfielders think they're closer to the wall than they really are.
