Beeks will serve as the Rays' opening pitcher for Wednesday's game against the Cardinals, Marc Topkin of the Tampa Bay Times reports.
Wednesday will mark the eighth start of the season for Beeks, who holds a 6.27 ERA and 1.47 WHIP through 37.1 frames on the season. The Rays are already planning on Wednesday's contest being a bullpen game, so Beeks will likely remain in the contest only for an inning or two.
