SEATTLE – Trevor May arrived at Safeco Field on Friday knowing things would be strange. He's not used to being in the visitors' clubhouse.

May, the ace for Kelso (Wash.) High School in 2008, dressed in the home clubhouse at Safeco Field before he led the Hilanders to the Washington state championship game with a strong outing in the semifinals. He returns Saturday to take the same mound, but this time for the Twins as they face the Mariners.

Kelso is about a two-hour drive down Interstate 5 from Seattle, so May expects some friends, coaches and about 15 family members to be in the stands Saturday.

"I'm just kind of excited to merge the two lives," May said. "Going into Safeco Field, going into the visitors' clubhouse is going to be weird. It will be a cool thing, and I think it will be a lot of fun, I think."

May played football for a year in high school and starred in basketball and baseball. But Kelso, no doubt, is a baseball town. Five players from the school have gone on to play in the majors, most notably pitcher Jason Schmidt.

"That's our best sport," May said, "We have had some top-five teams in the state."

May signed to play in college at the University of Washington, but he was drafted in the fourth round by the Phillies in 2008 and opted to begin his professional career instead. In 2011, May was ranked as the top pitching prospect in the Phillies farm system. A year later, he came to the Twins along with Vance Worley in exchange for Ben Revere.

May made his big-league debut last summer, going 3-6 with a 7.88 ERA in 10 outings in 2014. He came to spring training more focused and more prepared and nearly won a spot in the Twins starting rotation, before getting the call when Ricky Nolasco landed on the disabled list April 11 because of a sore elbow.

In his last start, May held Cleveland to one run over six innings Sunday. Now he faces a Seattle lineup with dangerous hitters in Robinson Cano, Nelson Cruz and Kyle Seager.

After the game, May plans to come out of the visitors' clubhouse to hug his parents, Ron and Terrie; his sister, Erin; and brother, Jordan. And he plans to pose for a picture with them while wearing his uniform.

"I just want to go out and continue to follow the process and improve and get us a win," May said. "Now I'm going into another situation that is different emotionally, and every time it's like if I can just stay on exactly what I'm doing despite what is going on around me I'll be ready for anything."

Nolasco pushed back

Righthander Ricky Nolasco was scheduled to start Saturday for Class A Cedar Rapids as he works his way back from elbow inflammation. But the weather forecast in Iowa isn't conducive to a rehabilitation start.

"There's a 90 percent chance of rain," Twins assistant General Manager Rob Antony said.

With sunny skies anticipated Sunday, Nolasco will pitch then.

That makes for an interesting weekend. Trevor May, who replaced Nolasco in the rotation when Nolasco landed on the disabled list, will start Saturday. If May pitches well, and Nolasco declares himself ready to return to the rotation Sunday, the Twins will have a decision to make.

Etc.

• Lefthander Brian Duensing, on the 15-day disabled list because of a strained right intercostal muscle, continues to do light throwing. There are no plans for him to throw in the bullpen yet.

• Seattle put righthander Hisashi Iwakuma on the 15-day disabled list because of a right lat strain. He had been scheduled to start against the Twins on Sunday, and the Mariners did not announce who would start in his place.
