Two of the most prominent sluggers in Mississippi college baseball history played a little version of home run derby in the eighth inning of an International League game Friday night at Omaha’s Werner Field. Matt Wallner, Southern Miss’ career homer leader, went deep for St. Paul, a two-run shot in the top half, and Brent Rooker, who led the SEC in homers in 2017 while winning the Triple Crown at Mississippi State, belted a three-run bomb for the host Storm Chasers in the bottom half. (St. Paul won the slugfest 15-6.) For Wallner, Minnesota’s No. 7 prospect, it was his first Triple-A home run in his 14th game at that level. He hit 21 in Double-A before his promotion. The left-handed hitting outfielder went 2-for-5 on Friday to lift his average to .179. He hit .299 in Double-A. Rooker’s homer was his second in his second game for Omaha following his trade to Kansas City from San Diego. He belted 19 at Triple-A El Paso, where he batted .272 for the Padres affiliate. The right-handed hitting outfielder, a former top prospect, has 95 minor league homers and 10 MLB bombs (all with Minnesota) in 67 big league games. He was the 35th overall pick by the Twins in the 2017 draft and was traded to the Padres just before this season began. P.S. Former George County High standout Justin Steele matched a career-high with 10 strikeouts for the Chicago Cubs on Friday. The lefty was pulled with two outs in the fifth inning after throwing 93 pitches against Miami. The Cubs won 2-1. … MSU product Dakota Hudson, in his second start for St. Louis since coming off the injured list, threw four-plus innings (78 pitches) against the New York Yankees, allowing three runs in a game the Cardinals would win 4-3.
