what’s that sound?

Matt Wallner is making noise in Triple-A, though it might not be enough just yet to pique the interest of the Minnesota Twins. Former Southern Miss standout Wallner homered for the fourth time in six games — that’s what he does — in St. Paul’s 6-1 win Sunday against Rochester. The left-hitting DH/outfielder is 8-for-29 (.276) in his last nine games, raising his average to .200. He has nine homers and 30 RBIs for the Saints. The Twins sent Wallner down on April 16, when he was 2-for-25 with one home run (off a position player). It appears Minnesota, contending in the American League Central, could use some outfield help, but Wallner likely will have to demonstrate more consistency before he gets a call. He has struck out 60 times (and walked just 20) in 150 at-bats for St. Paul. USM’s all-time homer leader, Wallner hit 14 in 76 games for the Twins last year, when he batted .249. For what it’s worth, he has a very good throwing arm. P.S. In his first start for Triple-A Gwinnett, USM alum Hurston Waldrep struck out 11 batters in six innings but allowed three runs — two on a first-inning bomb by Heston Kjerstad — and took the loss against Norfolk. Atlanta’s No. 2 prospect, Waldrep had a 2.92 ERA and 48 strikeouts in 49 1/3 innings for the Double-A Mississippi Braves this season.
