"He was trying to play through it," Mariners manager Scott Servais said. "He knew there was a small little crack in it, but it's one of those things you try to manage it as best you can, and then he kind of re-aggravated it on the homestand. You saw in the game on Sunday -- it was really bothering him.
"Speed being such a big part of his game, I just think the best thing to do is let that thing calm down. Not that it's going to completely heal in nine or 10 days, but certainly calm down enough to the point [that] hopefully we can get him back sooner than later."
The Mariners recalled first baseman/designated hitter Daniel Vogelbach from Triple-A Tacoma to take Gordon's roster spot. Vogelbach will join the team in time for Tuesday's series opener at Oakland.
With Cano gone until mid-August with his 80-game suspension and Gordon now sidelined, the Mariners' current second-base options are Gordon Beckham and utility infielder Andrew Romine.
Gordon, 30, initially injured the toe when he fouled a ball off it during an at-bat on May 9 at Toronto. Although X-rays taken revealed a small fracture, Gordon continued to play but further injured it in Sunday's 3-2 victory over the Tigers when he made a diving attempt at a bloop single into shallow right field by John Hicks in the top of the 11th inning.
Gordon remained in the game and singled, stole second and scored the winning run on a walk-off single by Jean Segura, but he was limping noticeably.
Surgery was never considered, according to Servais, and the team opted to leave Gordon at home to rest rather than have him on the road trip.
"You certainly saw it in the ballgame on Sunday, him taking off stealing, kind of limping around there to score the winning run," Servais said. "We just want to make sure he's 100 percent. We're going to need him. We just thought the best way was by calming this thing down right now. He knows he's not right. I think it started affecting him in the batter's box a little bit in his swing. He tried to play through it as long as he could. Just wasn't working."
The speedster is hitting .304/.330/.386 with an American League-leading 16 steals out of the leadoff spot for Seattle, which acquired him in a trade from the Marlins in December.
Vogelbach, 25, made the Mariners' Opening Day roster and slashed .204/.317/.352 with two home runs in 19 games before being optioned to Triple-A. In 24 games for Tacoma this season, he hit .301/.449/.711 with nine homers.
Designated hitter Nelson Cruz was held out of the starting lineup for a second consecutive day with a sore elbow after he was hit by a pitch on Saturday. The Seattle slugger missed two games last week after getting hit by a pitch in his right foot.
"We really need Nellie back in the lineup, no doubt, but we need the good Nellie being a force, driving in runs, doing what he can do. Just give him another day," Servais said.
