Rays starting pitcher Alex Cobb was effective over six innings Sunday against the Cubs, but the game was decided well after Cobb left his start, as Chicago won 3-2 in 12 innings.

Cobb was locked in a pitcher's duel with Travis Wood all afternoon. After Tampa Bay took a 1-0 lead in the top of the fifth inning, Chicago tied the game at 1 in the bottom of the fifth as Javier Baez had an RBI single off Cobb.

Baez's single was the only run allowed by Cobb, who gave up six hits and no walks in six innings. He struck out six.

Cobb has not taken a loss in his last eight starts, going 5-0 in that span. He has allowed two or fewer runs in six straight starts.

Cobb is on track to make his next start Friday against the Yankees.
