Yarbrough (0-4) took the loss Thursday in Toronto, allowing four runs on eight hits, a walk and a hit batsman in 5.1 innings in relief. He did not record a strikeout.
Yarbrough followed Matt Wisler's scoreless first inning by promptly giving up a single and a two-run homer to the first two batters he faced. He held the Blue Jays scoreless over the next four frames and then allowed another two-run homer in the seventh. It was his first appearance for the Rays after spending the better part of June playing for Triple-A Durham. Through 34 innings in the majors, he's posted a 5.82 ERA and 20:11 K:BB in a disappointing first half of the season.
