While the precise roster move to be made remains unknown, starter Jeff Francis will be removed from the Rockies' active roster tomorrow, writes Troy Renck of the Denver Post. The team will promote Roy Oswalt to start tomorrow's game at Washington.

As Renck explains, the club could seek to option Francis, but would need the veteran's consent to do so. Of course, a 40-man roster spot would presumably still need to be cleared under that scenario to make way for Oswalt. Otherwise, Colorado could designate Francis for assignment. Either way, says Renck, the lefty has had his locker cleared out and will not accompany the team to D.C.

Francis, 32, re-signed with the Rockies on a one-year deal with a $1.5MM base salary and another $1.5MM worth of incentives. In 52 innings this season, he's posted a 6.58 ERA with 7.4 K/9 and 2.9 BB/9. The strikeout rate is actually the highest of Francis' career, as is his 50.3 percent ground-ball rate. He's been hurt by a homer-to-flyball ratio (20.4 percent) that's nearly double that of his career mark.
