Polanco (hamstring) isn't in the Mariners' lineup for Tuesday's game against the Royals.

Right hamstring tightness forced Polanco out of Monday's contest, and he will get an additional day to recover Tuesday. Josh Rojas will cover second base as a result, allowing Luis Urias to start at the hot corner and bat ninth.

Gelof (oblique) was reinstated from the 10-day injured list and is starting at second base Tuesday against the Astros.

The 24-year-old has been sidelined nearly three weeks by an oblique strain and is back with Oakland after a two-game rehab assignment with Triple-A Las Vegas. Gelof had a slow start to the campaign with a .597 OPS through 24 games but should operate as the Athletics' primary second baseman now that he's healthy.

Frazier is out of the lineup for Tuesday's game against the Mariners.

Frazier will be out of the lineup for the second time in the last three games, with Michael Massey playing second base and Nelson Velazquez operating as the designated hitter.

Keith is out of the lineup for Tuesday's game against Miami.

Keith will yield to right-handed Andy Ibanez on Tuesday as the Tigers face southpaw Ryan Weathers. In May, Keith is batting .250 with five RBI and three runs scored across nine games.

Julien is not in the lineup for Tuesday's game against the Yankees.

With left-handed Carlos Rodon toeing the rubber for the Yankees, the lefty-swinging Julien will yield to Kyle Farmer at second base. Julien has made just two starts versus southpaws this season.

Rengifo (illness) fielded grounders Monday and could return from the injured list when eligible Friday, per MLB.com.

Rengifo came down with a viral infection in early May and landed on the IL when the illness caused painful blisters on his feet. His ability to take grounders Monday is a good indication that he's doing better, and there's a chance he could spend the minimum amount of time on the injured list. Upon his return, Rengifo should slide back into a starting role at third base -- Niko Goodrum, Luis Guillorme and Cole Tucker have been filling in at the hot corner in his stead.

Stefanic (quadricep) began a rehab assignment in the rookie-level Arizona Complex League on Monday, starting at second base and playing three innings while going 1-for-2 with an RBI.

On the mend from a left quad strain since late February, Stefanic has reached the final stage of his recovery program now that he's back playing in minor-league games. Since he's been out of commission for nearly two and a half months, Stefanic will presumably stick around in Arizona for a few more games before continuing his rehab at one of the Angels' higher-level affiliates. Once the Angels are confident that he's regained his timing at the plate and has put the quad injury in the rear-view mirror, Stefanic could return from the 60-day injured list around when he's first eligible in late May. He'll likely be ticketed for a utility role once he's reinstated, though Stefanic has a minor-league option remaining and could be sent to Triple-A Salt Lake if the Angels don't have room for him on the big-league roster.

Polanco was removed from Monday's game against the Royals due to right hamstring tightness.

The severity of Polanco's injury is unclear, though he's likely headed for further testing. Josh Rojas and Luis Urias could see more opportunities at second base if Polanco is forced to miss additional time.

Schuemann will start at shortstop and bat seventh in Monday's game against the Astros.

Schuemann will pick up his sixth consecutive start after going 5-for-19 with a home run, two doubles, two walks, four RBI and three runs over Oakland's previous five games. He looks poised to operate as the Athletics' primary shortstop while Darell Hernaiz is on the injured list with a severe ankle sprain.

Gelof (oblique) rejoined the Athletics on Monday and could be activated from the 10-day injured list during their four-game series in Houston, Martin Gallegos of MLB.com reports.

Gelof played consecutive full rehab games with Triple-A Las Vegas on Saturday and Sunday, which was the last box he needed to check before returning to the big club. The Athletics seem content to give Gelof a rest day Monday before likely activating him ahead of Tuesday's contests. Gelof has been out since late April with a strained left oblique.
