"I hope not, but it did hit me right in the spine," McCutchen said of the Randall Delgado fastball ostensibly delivered as payback for Ernesto Frieri having fractured Arizona first baseman Paul Goldschmidt's left hand the night before. "So it was tight, stiff a little bit. And I had to get a little bit of [pregame] treatment.
"But I went through my warmups fine, no issues, hitting and all that. It wasn't a major issue besides being bruised. But the side has never been a problem ever in my life, so I've never had to deal with this, so who knows."
It became an issue as McCutchen drove a game-tying sacrifice fly to left field. He grabbed his left side a few strides down the first-base line and, after watching Josh Harrison cross the plate, walked slowly toward the Bucs' first-base dugout, never taking his left palm off his side. He had to be helped making is slow way down the steps into the dugout, and needed further help as he walked into the tunnel leading to the clubhouse.
"The last swing … I really don't know," McCutchen said, trying to pinpoint the source of the discomfort. "I thought it was cramping. I've never had problems in that area."
X-rays "were fine," said McCutchen, who should have a clearer idea of his prognosis as he undergoes further evaluation on Monday, an off-day for the club.
"We won't know till tomorrow," he said. "See how I feel, and go from there."
