(Sports Network) - Right-hander Todd Wellemeyer goes for an eighth start without a loss tonight when the St. Louis Cardinals host the Pittsburgh Pirates in the second and final game of an abbreviated two-game set at Busch Stadium.

Wellemeyer, who'll turn 30 on August 30, was coming off a two-start skid when he last faced the Pirates on July 12, allowing four hits and four runs en route to a no-decision in 6 1/3 innings of the Cardinals' 12-11 loss.

He's 3-0 in six starts since, allowing 31 hits and 13 runs in 37 2/3 innings.

He allowed three hits in 7 2/3 scoreless frames in his last outing, a 3-0 defeat of the Florida Marlins in Miami.

Wellemeyer is 3-1 in 16 lifetime matchups - five starts - against the Pirates with a 3.40 earned run average.

Tennessee-born righty Jason Davis looks for his first 2008 win as a starter with the Pirates.

The 28-year-old, who split 2007 between Cleveland and Seattle, began this year with four bullpen appearances for Pittsburgh before an Aug. 10 start at Philadelphia.

Davis allowed four hits and a pair of unearned runs over six innings in that game, won by the Phillies, 6-3.

He followed up with a seven-inning outing in which he allowed six hits and two runs in a 2-1 loss to the New York Mets.

Overall, in six games, he's given up just 16 hits and four earned runs in 20 innings.

He has never faced the Cardinals.

On Tuesday, Ian Snell mastered the Cardinal bats for seven shutout innings and Ryan Doumit had three hits and an RBI, as Pittsburgh took the opener, 4-1.

Snell (5-10) scattered four hits with one walk and eight strikeouts, breaking out of a rough stretch in which the right-hander had just one win in his last 10 starts.

Braden Looper (11-10) pitched well enough to win but was victimized by a suspect bullpen performance, allowing only one run on three hits with a pair of walks and as many strikeouts over seven frames.

He did continue an impressive streak in which the right-hander has allowed three runs or less in each of his last six starts.

Pittsburgh has won seven of its 13 meetings with the Cards this season.
