Adam Wainwright has no concerns or lack of confidence coming into Game 4 of the NLCS, Thursday night at 7 p.m. CT, when the Cardinals look to grab a 3-1 lead in the series of the San Francisco Giants.

Wainwright talked about his last outing on Friday which should have been the final game of the season, but he gets another shot at redemption. He points to three pitches he left up in the zone that got crushed as the main reason that game got out of hand so early, in falling behind 6-0. He also conceded the fact that was his third straight game pitching against the Nationals and perhaps he was too predictable.

However, Wainwright is not concerned about his arm or his pitches. He says his curveball is the best it’s ever been and his arm feels better than at any other time in his career.

Wainwright has stumbled over the final month of the season in his last seven starts. He’s just 1-2 and has allowed 21 earned runs in 38 innings, for an ERA of 4.97.
