Andre Rienzo, the White Sox right-hander with the name like an opera singer, turned in a perfect inning for the World team in Sunday's Futures Game.

Rienzo, who is 6-6 with a 4.47 ERA in 18 starts for Triple-A Charlotte, retired Austin Hedges, Billy Hamilton and Delino DeShields Jr. in order in the third inning.

He has been pounding the strike zone recently (four walks in 302/3 innings over his last four starts) and continued that trend. He needed only 10 pitches to work his inning, mixing 90-mph fastballs with cutters in the high-70s.

Rienzo represented Brazil in the World Baseball Classic.

Moving on up: Birmingham Barons manager Julio Vinas worked as a coach for the World team. His team is 57-38 and won a first-half division championship in the Southern League, in part because of the pitching of White Sox prospect Erik Johnson.

"He was able to work both sides of the plate with his fastball, and he was getting his breaking ball over the plate for strikes,'' Vinas said. "It was fun to watch him pitch.''

Johnson went 8-2 with a 2.23 ERA in 14 starts before being promoted to Triple-A Charlotte. Vinas said infielder Marcus Semien and catcher Michael Blanke have been among his most consistent players. He said he has enjoyed watching the development of outfielders Trayce Thompson, Jared Mitchell and Keenyn Walker, but all three have struggled at the plate. "They're starting to hit,'' he said.
