SEATTLE — The Seattle Mariners optioned starting outfielder Nori Aoki and relief pitcher Tom Wilhelmsen to Triple-A Tacoma on Friday to clear space for pitching reinforcements.

The Mariners made seven roster moves before starting a homestand against St. Louis. The Mariners also placed right-hander Adrian Sampson on the 15-day disabled list and brought up left-handers Wade LeBlanc and David Rollins and right-hander Donn Roach from Tacoma. Seattle also transferred right-hander Tony Zych to the 60-day DL.

LeBlanc was set to start for Seattle on Friday night. It’s his first start in the majors since 2014.

Aoki had started 67 games this season but was hitting just .245. He was demoted from the leadoff spot in the batting order recently and Seattle manager Scott Servais said he wanted Aoki to work on hitting against left-handers while in the minors. Aoki is hitting .177 against lefties this season.

ANGELS: Los Angeles reinstated right-hander Nick Tropeano from the disabled list and optioned him to Triple-A Salt Lake.

Tropeano had been on the disabled list since June 4 with tightness in his right shoulder. He is 3-2 in 10 starts for the Angels with a 3.25 ERA, the best among Los Angeles’ starting pitchers.

After a season of injury problems for the Angels, they have six healthy starters after Tim Lincecum’s addition to the big league roster last weekend.

Despite his solid performances this season, Tropeano is one of just three starters who can still be optioned without going on waivers.

RAYS-TWINS TRADE: The Tampa Bay Rays have addressed a need for help in the outfield by acquiring left-handed hitting Oswaldo Arcia from the Minnesota Twins in exchange for a player to be named or $45,000.

The move was made to bolster an outfield that’s missing starters Kevin Kiermaier and Steven Souza Jr., as well as reserves Brandon Guyer and Mikie Mahtook, who all are on the 15-day disabled list.

The Rays cleared room on the 40-man roster by designating right-handed pitcher Andrew Bellati for assignment. The team will announce another move to open a spot on the active roster.

REDS: Pete Rose is being inducted into the Cincinnati Reds’ Hall of Fame and having his No. 14 officially retired over the weekend, 27 years after he was banned from baseball for betting on the Reds.

“This will be the ultimate thing to happen to me so far in my baseball career,” Rose said. “I tell people you should put it on your bucket list to go to the Reds’ Hall of Fame, and I’m happy to be in there. It seems like everybody I played with is in there, so they might as well put me in there, too.”

The Reds have turned the Rose honors into a weekend gala. They reunited members of their 1976 Big Red Machine championship team on the field Friday night before a game against the San Diego Padres. Rose was the last player introduced but didn’t speak to the crowd.

NATIONALS: Right-hander Stephen Strasburg will return to start Sunday against the Milwaukee Brewers after skipping his last scheduled appearance with an upper back strain.

Strasburg was scratched from an anticipated showdown against Los Angeles Dodgers ace Clayton Kershaw on Monday.
