NEW YORK -- Matt Cain hopes he never again hits a batter as sickeningly as he struck David Wright of the New York Mets on Saturday.

But Cain would rather accept the physical punishment of a retaliatory pitch -- which is part of accepted law in the baseball jungle -- than see a teammate get hit.

Said the Giants right-hander on Sunday: "I don't know if it's the right way to do it, but honestly, if the other guy's pitcher is going to hit somebody, why not hit me if he thinks I did it on purpose?"

Cain noted that he wasn't worried that Mets starter Johan Santana would throw at him after Wright was hit "because it wasn't done on purpose at all."

Giants manager Bruce Bochy wasn't concerned about hostilities carrying over into Sunday's game, though both starting pitchers -- San Francisco's Jonathan Sanchez and New York's Mike Pelfrey -- occasionally struggle with control and might hit a batter with no malice intended.

"There's no history here," Bochy said. "I don't think anybody's thinking about that. Hopefully we'll go out there and play a good, clean game."

Cain left a message on Wright's cellular phone to convey his concern and regret. After being hospitalized overnight, Wright rested at home Sunday while recovering from post-concussion symptoms. The Mets placed Wright on the 15-day disabled list after Sunday's game.

To purge himself further of the unpleasant experience, Cain dwelled on it just a little longer. He watched replays of the incident in his hotel room Saturday night on ESPN's "SportsCenter" -- along with footage of Dodgers pitcher Hiroki Kuroda being struck by a line drive and Rangers second baseman Ian Kinsler getting hit by a pitch that grazed his left shoulder before beaning him.

"Sometimes it's all right to see it and kind of let it go," Cain said. "That's definitely not a situation either David or I want to be in."

Cain also felt the impact, figuratively speaking, of Wright, Kuroda and Kinsler all absorbing blows to the head on the same day.

"It's a horrible situation for all three guys," Cain said.
