Pittsburgh Pirates vs. St. Louis Cardinals FREE LIVE STREAMING MLB From Busch Stadium at 2:15 PM ET

Adam Wainwright (4-1, 1.46 ERA) went 2-0 with a 1.13 ERA and 15 strikeouts in two home starts against Pittsburgh in last year's NL division series, closing out the Pirates by scattering eight hits in a 6-1 victory in Game 5.

The right-hander has been similarly dominant so far this year, ranking among baseball's leaders in ERA, WHIP (0.81) and opponents' batting average (.165).

He yielded four hits over seven innings in Tuesday's 3-0 road victory over the Mets. The only thing that stopped Wainwright was a hyperextended right knee that caused him to leave after 79 pitches, but he has been cleared and says there is only pain when his leg is fully extended.

"When you look at the way I pitch, you barely do anything stiff-legged, so I'm going to be OK," he told the Cardinals' official website.

Wainwright's lone defeat this year came April 6 against the Pirates, as he yielded two runs in seven innings of a 2-1 road loss.

Edinson Volquez (1-1, 1.93) will oppose Wainwright again after allowing one run over 5 2/3 innings in that contest and not receiving a decision. Volquez suffered his first loss Tuesday, yielding two runs in seven innings of a 4-1 loss to Cincinnati as he was up against another outstanding starter in Johnny Cueto.

The Pirates right-hander is 1/3 with a 6.26 ERA in five career starts at Busch Stadium.

Pittsburgh (10-15) will likely want to see a lengthy outing from Volquez since its bullpen was forced to work the final seven innings in Saturday's 6-1 victory.

St. Louis (13-12) has dropped five of seven, scoring a major league-low 10 runs over the previous seven days. The Cardinals haven't homered in 10 games.

Pittsburgh ended a season-high four-game slide Saturday.
