Rays-O's nightcap sees pair of sixth-inning challenges

BALTIMORE -- The Rays-Orioles nightcap saw a pair of challenges in the sixth inning.

With one out in a game tied at 1 in the top of the frame, Rays center fielder Kevin Kiermaier bunted and was called out at first base.

Kiermaier's bunt down the first-base line forced Orioles starting pitcher Chris Tillman to race off the mound to make a play. Tillman picked up the ball and flipped it over to Chris Davis at first base.

First-base umpire Jim Wolf called Kiermaier out, but after review, the play was overturned and Tampa Bay had a runner on first with one out. Kiermaier was stranded at third when James Loney popped out to end the inning.

Rays manager Joe Maddon is now 9-for-27 in challenging plays this season.

The Orioles challenged a play in the bottom of the frame when Rays pitcher Juan Carlos Oviedo picked off Manny Machado.

Machado drew a two-out walk after Nick Hundley homered earlier in the frame to make it 2-1, and Oviedo picked him off with Adam Jones up. First-base coach Wayne Kirby, Machado and manager Buck Showalter protested to Wolf before the skipper challenged the call. The out call stood after review, ending the inning.
