Mariner fans were already anticipating the debut of a touted prospect Thursday night.

Now it will be two.

Outfielder Jarred Kelenic, who The Seattle Times confirmed earlier this week would be called up to the big-league team for Thursday’s game at home against Cleveland, will be joined by the team’s top pitching prospect: right-handed starter Logan Gilbert.

Gilbert will start Thursday’s game for the Mariners.

The Seattle Times reported Tuesday that the Mariners were considering calling up Gilbert to start Friday’s game against Cleveland. The timetable was moved up a day.

Mariners manager Scott Servais said he won’t have a lot of advice for Kelenic and Gilbert.

“Try to put a smile on your face and go have fun,” Servais said of what he would tell them. “It’s going to be an exciting day for those young players tomorrow and looking forward to having them on our roster and see what they can do. They have very bright futures.”

Chris Flexen was scheduled to start Thursday. His start could be pushed back a day.


Gilbert, who was taken No. 14 overall by Seattle in the 2018 MLB draft, made one appearance for the Rainiers, allowing one run and striking out four in five innings on Friday.

Gilbert, 24, starred at Stetson University before joining the Mariners organization.

He was 10-5 with three teams — Class AA and Class A — in 2019, with a 2.13 ERA. He struck out 165 and walked 33.

Servais said one of the players who will be optioned to Class AAA Tacoma to make room for the new additions is rookie outfielder Taylor Trammell, who hit .157 with four homers in 83 at-bats.

“I thought Taylor Trammell showed us a lot of positive things,” Servais said. “We went without our regular center fielder (Kyle Lewis) for the first three weeks of the season and we would have really been in a bind if Taylor Trammell had not stepped up and played the way he did.

“I thought defensively he did a lot really good things and he helped us win some ballgames. … There is a lot to like, he just needs to play. He needs to play every day.”


Servais said “Tommy John surgery is in the mix” for right-handed pitcher Ljay Newsome, who was hurt in Saturday’s game against Texas and was placed on the injured list Sunday.

“There might be some other ways to go … and he has not made a decision,” Servais said. “Like anybody would be, he was bummed out. … He has never had an arm injury (before).”
