Sonny Gray struck out nine over six strong innings, newcomer Mike Moustakas homered to highlight a three-hit, four-RBI game, and the Cincinnati Reds opened the shortened season with a 7-1 home rout of the Detroit Tigers on Friday night.Joey Votto homered in the fifth inning for one of his two hits for the Reds, who are filled with lofty expectations — thanks to the additions of Moustakas and Nick Castellanos — while trying to reach the postseason for the first time since 2013.In the opener, it was Gray and Moustakas who led the way.The veteran right-hander topped the 1,000-career strikeout mark while allowing one run on three hits and two walks. Gray’s only blemish was a deep, solo homer by C.J. Cron in the fourth inning.The Reds didn’t waste any time getting on the board, mostly taking advantage of control issues from Detroit starter Matthew Boyd in the first inning. After leadoff hitter Phillip Ervin walked, Votto singled and Eugenio Suarez and Castellanos were each hit by pitches. Moustakas’ single put Cincinnati up 2-0 before the home team surrendered an out.Moustakas came through with another RBI single in the third to make it 3-0 and crushed a two-run homer to right field in the seventh to help Cincinnati break things open. Touted Japanese import Shogo Akiyama also had a run-scoring single in his Reds debut.
