In announcing the trade of Cameron Maybin on Thursday, Detroit officials said there would be “a wide-open competition” for the center field job in spring training. Former Richton High star JaCoby Jones will be in the mix. Jones, who can also play the infield, is playing center field in the Arizona Fall League and batting .318 with a homer, eight RBIs and five steals in 13 games for Salt River. He went 6-for-28 in a big league trial this summer. In four minor league seasons, the 6-foot-2, 205-pound Jones is hitting .269 with 47 homers and 58 bags. The Tigers acquired him in 2015 from Pittsburgh, which drafted Jones in the third round in 2013 out of LSU. … Seattle picked up the 2017 option on Seth Smith’s contract. The Jackson native and Ole Miss alum, a lefty-hitting outfielder, batted .249 with 16 homers for the Mariners in 2016, his second year with the club and 10th in the majors. … Chris Maloney, a Jackson native and ex-Mississippi State standout, will be back for a sixth year on the St. Louis coaching staff in 2017. Maloney coached third base for manager Mike Matheny this past season.
