Imanaga (5-7) took the loss Saturday against the Cardinals, allowing two runs on four hits and three walks in 4.2 innings. He struck out eight.
Imanaga had plenty of swing-and-miss stuff going, fanning eight and generating 16 whiffs, but he was still inefficient with 86 pitches on the evening. Saturday disrupted a seven-start streak of at least five innings for the 32-year-old left-hander, who also tied a season high in walks. Imanaga is next lined up for a relatively tough assignment at hitter-friendly Great American Ball Park in Cincinnati, holding a 4.28 ERA, 1.10 WHIP and 100:26 K:BB over 103 innings.
