Every team needs an ace, and Southern Miss has one. One of the best, in fact. Nick Sandlin — C-USA pitcher of the year, Ferriss Trophy winner – has been terrific. The converted closer moved to 9-0 and trimmed his ERA to 1.13 with a four-hit, 12-strikeout performance against UAB in the C-USA Tournament opener on Thursday in Biloxi. But the Golden Eagles (41-15) will need more than one golden arm to make a run in the NCAA postseason (which could well start in an Oxford Regional). Do they have that kind of depth? They just might. The other pitchers don’t get the pub afforded Sandlin, but this is a team with a staff ERA of 3.58. Both Stevie Powers and Walker Powell, the other weekend starters, have won big games. Powers, a left-hander who last pitched on May 5 because of some arm issues, notched the win on Friday, yielding two runs in seven innings in a 5-3 victory against Texas-San Antonio. He joked about following Sandlin in the USM rotation. “It’s been a tough job all year for me,” he said in a school release. He’s been up to it, going 5-1 with a 3.28 ERA. Powell, typically the No. 3, is 7-3, 3.62, and will start today in the semifinal round of the tournament. In the bullpen, Cody Carroll (2.23), Keller Bradford (3.24), Mason Strickland (3.25) and Trent Driver (4.30) have been effective, and large-looming, hard-throwing Matt Wallner has six saves despite a 7.36 ERA in his 11 appearances. Sandlin certainly leads the way for this staff, but coach Scott Berry has more cards to play than just his ace.
