Calf cramping forces Wada's exit in fourth

CHICAGO -- Cubs pitcher Tsuyoshi Wada had to leave Friday's game in the fourth inning because of cramping in his left leg but was not expected to miss his next start.

With one out in the frame, Wada walked Neil Walker before serving up a double to Jose Tabata that sailed over center fielder Arismendy Alcantara, tying the game at 2.

Wada, who was making his 10th start for the Cubs, threw two pitches to Vance Worley before athletic trainer Ed Halbur went to the mound. He was joined by catcher John Baker, pitching coach Chris Bosio and manager Rick Renteria. After consulting with Wada, the pitcher was then pulled from the game.

The Cubs said Wada had mild left calf cramping. The weather may have been a factor, as it was a steamy 88 degrees and very humid at Wrigley Field.

"I believe [the heat was the problem]," Wada said. "This was something I experienced in Japan in the past as well, so I felt it kind of came up again."

Wada hit two batters in a row in the third inning, and he said that's when he first experienced the cramp in his leg.
