(CINCINNATI) – Mike Moustakas drove in four runs in an emphatic first impression, teaming with fellow Cincinnati newcomers Shogo Akiyama and Nick Castellanos to turn the Reds' long-delayed opener into a 7-1 victory over the Detroit Tigers on Friday. The Reds tried to make themselves relevant again by spending $165 million on free agents in the offseason. Moustakas and Castellanos each got $64 million as cornerstones of the rebuild. They combined to produce Cincinnati's first three runs, and Moustakas added a two-run homer as the Reds were off and running. Akiyama, signed as a free agent after a stellar career in Japan, singled home a run in his first at-bat as a pinch hitter. Joey Votto added a solo homer. Starter Sonny Gray (1-0) fanned nine and gave up three hits in six innings, including C.J. Cron's homer that clanked around the empty metal bleacher seats in the upper deck. Gray extended his major league record to 34 consecutive starts without allowing more than six hits. Matthew Boyd (0-1) had trouble in his first opening start, immediately loading the bases on a walk, hit, and a hit batter. Up came Castellanos, a former Tiger, and he got plunked, too, getting his first RBI with the Reds without swinging the bat. Boyd needed 26 pitches to get the first out and 30 overall in the first inning, when manager Ron Gardenhire got his bullpen warming up. Boyd lasted five innings and gave up four runs on six hits.
