One has to wonder if the Minnesota Twins are considering a promotion for Brent Rooker, who is wearing out the rookie-level Appalachian League. The ex-Mississippi State star – the 35th overall pick last month — has 12 hits in his last seven games for Elizabethton and is at .323 with five home runs and 10 RBIs in 16 pro games. The 6-foot-3, 215-pound Rooker has been playing left field; he played mostly first base at State this year. … Rehabbing big leaguer Sean Rodriguez went 1-for-5 with four strikeouts for the Mississippi Braves in an 8-7 loss to Jackson (Tenn.) on Tuesday at Trustmark Park in Pearl. The M-Braves fanned 11 times all told and dropped to 4-14 in the second half of the Southern League season. They play the Generals again tonight at the TeePee. … Blake Anderson, the former West Lauderdale High star catcher, is now listed as a pitcher on the roster of the Gulf Coast League Marlins. Anderson, widely hailed for his defensive abilities, was a supplemental first-round pick by Miami in 2014. Injuries have limited him to 58 pro games (one in 2016), and he carries a .173 average. He has not appeared in a game this season. … None of the four high school players drafted out of the state this year signed to play pro ball. Myles Christian of Olive Branch, the highest prep pick (18th round, Seattle), is bound for Middle Tennessee State. C.J. Dunn of Center Hill, a Toronto pick, is going to Texas Tech; Ocean Springs’ Garrett Crochet, a Milwaukee pick, is off to Tennessee; and McLaurin’s Davis Bradshaw, another Brewers draftee, will play at Meridian Community College in 2018. The state’s Gatorade player of the year, Trey Shaffer, a left-hander from Biloxi, wasn’t drafted. The Southeastern Louisiana signee went 8-1 with a 1.20 ERA for the Indians. He also hit .380. … The only other 2017 draftees who didn’t sign were Mississippi State’s Jake Mangum, Ole Miss’ Brady Feigl and East Mississippi Community College’s Marcus Ragan, who is bound for Arkansas-Little Rock. State’s Cody Brown (New York Yankees) and Southern Miss’ Tracy Hadley (Chicago White Sox) signed as non-drafted free agents. … The Mississippi Semi-Pro State Tournament is scheduled for Thursday through Sunday at Jackson’s Smith-Wills Stadium. Among the participants will be the Hattiesburg Black Sox, who won the Magnolia Adult Baseball League title. … USA Baseball has unveiled the 40-man group that will go to Minneapolis in August to take part in the 18U National Team Trials. Pitcher J.T. Ginn of Brandon and outfielder Joe Gray of Hattiesburg made the cut. The team trials begin on Aug. 19 and the final 20-man roster will be announced on Aug. 24. The 18U National Team will compete in the World Baseball Softball Confederation U-18 World Cup in Thunder Bay, Canada, from Sept. 1-10.
