SAFECO FIELD - Leonys Martin said he feels "pretty good" after taking several at-bats and running the bases during a simulated game on Wednesday.

Martin, who was placed on the disabled list with a hamstring strain on May 27, will join Triple-A Tacoma for a rehab start on Thursday night. If all goes to plan, Martin expects to re-join the Mariners on Friday when he's eligible to be activated from the disabled list.

"Amazing," Martin said. "It feels like day one of spring training. I feel great, man."

Martin did some sprinting in the outfield before taking several swings against former Mariners minor league pitcher Jarrett Grube. Martin even hit one home run in the several at-bats he took in the simulated game.

Martin is expected to play seven innings in the outfield with Tacoma on Thursday night.

"Looked like he hadn't missed a beat," manager Scott Servais said. "Smoking balls all over the park, hit one out. Good."

"Hopefully, if that goes good we can see him here on the weekend. As soon as Friday."

Marte back in lineup:

Shortstop Ketel Marte is back in the lineup and batting eighth a night after being scratched due to neck spasms.

Marte felt his neck tighten up during batting practice on Tuesday and was pulled from the lineup. He said he was already feeling better after the game last night and told Servais he was ready to go today.

"Came in, feels good today," Servais said. "'Tell Mr. Coach I'm ready to play.' So he's good."
