Five Mississippians made their big league debut in 2019: Chris Ellis, Nate Lowe, Austin Riley, Jacob Waguespack and Bobby Bradley. Who’ll be next to break through? Smart money would be on Demarcus Evans, the former Petal High standout who recently was added to Texas’ 40-man roster. A right-handed reliever – and strikeout machine — he hasn’t pitched above Double-A but will go to spring training with a chance to make the opening day roster. Minnesota has an opening at first base after non-tendering C.J. Cron, and ex-Mississippi State star Brent Rooker could well be among the candidates vying for the job come spring. Rooker has All-World credentials, having earned that designation with his performance in the World Baseball Softball Confederation Premier 12 tournament, during which he hit three homers in 20 at-bats, including a big game-winner (see previous post). The three-year pro batted .281 with 14 homers in 65 games in Triple-A in 2019. He isn’t currently on the Twins’ 40-man and didn’t play any first base last year but does have experience there. George County High product Justin Steele is still on the Chicago Cubs’ 40-man roster and is rated their No. 11 prospect (MLB Pipeline). But the left-hander is coming off an injury-dampened season that saw him go 0-6 with a 5.59 ERA in Double-A. About to enter his seventh pro campaign, he needs to break through soon. Delta State alum Trent Giambrone is not on the Cubs’ 40-man but had a solid Triple-A season (.241, 23 homers, 17 steals) and could be in the mix for a role as a utility player in 2020. He is No. 28 on the Cubs’ prospect chart. Former MSU star Jacob Robson, a lefty-hitting outfielder, batted .267 with nine homers and 25 steals in Triple-A for Detroit and figures to get a long look in the spring, as does Ole Miss product David Parkinson, a lefty starter who was 10-9, 4.08 for Philadelphia’s Double-A club. Robson is the Tigers’ No. 27 prospect, Parkinson the Phillies’ No. 18. Neither is on the major league roster. … Another debut to watch for is that of Ke’Bryan Hayes, son of Hattiesburg native and ex-Forrest County AHS and MLB star Charlie. The younger Hayes, who was born in Texas, is Pittsburgh’s No. 2 prospect and recently was added to the 40-man roster. A plus-defender at third base, Hayes batted .265 with 10 homers at Triple-A in 2019. He’ll probably be in the opening day lineup.
