Cincinnati (1-0-1) took advantage of a pair of errors by the Indians in the opening frame and sent Jimenez to the showers earlier than expected. Miguel Cairo contributed a two-run single in the first inning, and Willie Harris added an RBI single.
Jimenez was charged with five runs, but only one was earned because of a fielding error by first baseman Russ Canzler and a throwing error by right fielder Aaron Cunningham. Jimenez threw 37 pitches (25 strikes) and ended with one strikeout, one walk and five hits surrendered.
"I threw the pitches that I needed to throw," Jimenez said. "What can I say? You never want the score to be like that, but I was throwing a lot of strikes and I used sliders and fastballs, and they were good. The guys just kept hitting soft bloopers. They only hit the ball hard one time."
Trailing 5-0, the Indians (0-1-1) quickly countered in the home half of the first inning. Against Reds starter Homer Bailey, Cristian Guzman drew a walk, Canzler chipped in a single and Shelley Duncan brought them both home with a monstrous home run to left field to trim Cincinnati's lead to 5-3.
"The home run, to me it looked like it was a letter-high fastball where I wanted to throw it," Bailey said. "Shelley just got on top of it. What can you do?"
Overall, Bailey gave up three runs on four hits in his two innings for the Reds. He was followed by left-hander Aroldis Chapman, who struck out three and finished with one run allowed on two hits and a walk in his two innings on the hill. Lefty Sean Marshall yielded two runs in the fifth inning, cutting the Reds' lead to 7-6.
Right-hander Josh Tomlin, who will likely open the year as either the No. 3 or No. 4 starter, turned in two shutout innings in his Cactus League debut for the Tribe. Tomlin allowed a pair of leadoff hits, but he limited the damage by recording two strikeouts and creating four outs via ground balls.
In the eighth inning, Reds catcher Dioner Navarro added a solo home run off Indians Minor League right-hander Rob Bryson to put Cincinnati up, 8-6.
