Athletics' Zack Gelof: Activation appears imminent

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.
