Two more Mississippians had their postseason tickets punched on Tuesday: Austin Riley is in with Atlanta and Billy Hamilton (presumably) with the Chicago Cubs. Ex-DeSoto Central High star Riley did not make the Braves’ postseason roster in 2019 following his rookie year. He hit 18 homers last season but, after a hot start, slumped down the stretch. He has made strides in 2020, batting .239 with eight bombs in 50 games while striking out less and walking more. His defense at third base has been excellent. (In addition to Riley, seven other Mississippi Braves alumni played in Atlanta’s division-clinching win against Miami, its third straight title under former M-Braves manager Brian Snitker.) Taylorsville High product Hamilton was with the Braves in 2019 and got his first taste of the postseason, though he appeared in just two games in the division series loss. He’s not a lock to make the Cubs’ roster, but his speed can be a valuable asset in the outfield and as a pinch runner. He has appeared in nine games for Chicago and is 0-for-1 in steal attempts. … Regardless of whether St. Louis makes the playoffs, former Mississippi State star Dakota Hudson won’t be on the postseason roster. The right-hander was moved from the 10-day to the 45-day injured list on Tuesday with a strained elbow suffered last week. He was 3-2 with a 2.77 ERA.
