ST. PETERSBURG -- Center fielder Desmond Jennings was scratched from the Rays' lineup Friday night with left knee soreness just before the club's 7:10 p.m. ET series opener against the Red Sox at Tropicana Field.
"[It was] real late," manager Joe Maddon said after the Rays' 8-4 loss. "It was like 7:02 or something like that when we had to scramble to redo the lineup."
Jennings was listed as day to day.
Jennings had been slated into his usual leadoff spot. Brandon Guyer, who hit a two-run homer, took Jennings' spot in the order, but he was placed in left field.
To adjust their outfield alignment, the Rays moved Kevin Kiermaier from right field to Jennings' spot in center, where Kiermaier has occasionally spelled Jennings this year.
Matt Joyce, who had been starting in left field, moved over to right.
