Mariners manager Scott Servais expected Smith, who was scheduled to be the designated hitter to be able to start when he met with reporters Sunday morning, but Smith was scratched a short while later. Dae-Ho Lee replaced Smith at DH and batted sixth, while third baseman Kyle Seager moved up to the two-spot in the lineup.
Lee is hitting .105 in his last 15 games with one homer. Nelson Cruz started in right field for Seattle.
Paxton to start Tuesday
Servais said after Sunday's 8-4 victory over the A's that James Paxton will start Tuesday against the Angels, more than a week after leaving a start against the Angels after being hit by a line drive in the left elbow.
"I feel good about where he's at right now," Servais said before Sunday's game.
Paxton threw a bullpen session Saturday -- his first since the injury -- and reported no issues.
The injury initially provided the Mariners a scare, but X-rays returned negative and it was deemed a bruise of the left elbow. Paxton is 4-5 with a 3.53 ERA in 13 starts this season.
Servais said the team still doesn't have a starter for Wednesday's game against the Angels, adding the team will continue to evaluate its internal options, with Ariel Miranda and Joe Wieland being chief among them.
"We're day to day at this point," he said. "We're playing it that way probably until Sept. 1 when we can expand the rosters."
When the Mariners demoted a struggling Taijuan Walker to Triple-A Monday, Servais said Walker needed to pitch deeper into games and begin to pitch more effectively before returning. Walker made his first start since the demotion Saturday, allowing four runs in 4 1/3 innings while giving up six hits and walking four on the road against Memphis.
