The Arizona Diamondbacks (32-25) and St. Louis Cardinals (38-19) will meet in a Tuesday night matchup at Busch Stadium set for 8:15 p.m. ET. The game will air live on Fox Midwest and can be streamed with a paid subscription on MLB.com.

Both teams' success to date is due largely to strong pitching. The Cardinals have a 2.96 ERA that tops the majors, while Arizona ranks seventh with a 3.64 mark.

Each sends a highly regarded young pitcher to the mound Tuesday night, with Michael Wacha (0-0) looking to guide St. Louis to an eighth victory in 10 tries in a matchup with Tyler Skaggs (1-0) and the visiting Diamondbacks.

Wacha had an impressive major league debut against Kansas City on Thursday. He allowed just one run and two hits while striking out six in seven innings of a 4-2 loss. The bullpen allowed three ninth-inning runs, giving up Wacha's opportunity to capture his first career win.

"Definitely just one to remember," Wacha said. "Once I threw the first pitch for a strike I really calmed down and was able to execute my pitches pretty well."

The 21-year-old was drafted out of Texas A&M University in the 2012 amateur draft by the Cardinals with the No. 19 overall pick. Wacha had a 4-0 record with a 2.05 ERA and 34 strikeouts while playing for the AAA Memphis Redbirds before being called up by St. Louis.

Skaggs contributed to the Diamondbacks impressive ERA in his first start of the season May 27. Called up to start the first game of a doubleheader, he gave up three hits and struck out nine in six scoreless innings of a 5-3 win over Texas.

"I'm happy that they called me up and had the confidence in me," said Skaggs, who went 1/3 with a 5.83 ERA in six starts last season. "Hopefully I opened up a few eyes."
