Castro, though, feels the Astros won't be intimidated."We're comfortable now, I think, with the way he likes to pitch and the way he goes about attacking hitters," Castro told the team's official website. "We kind of learned and made some adjustments based on that first time we saw him."Astros third baseman Matt Dominguez became the only player to homer twice against Darvish in one game in May.Houston has struck out a major league-high 808 times, while Darvish leads baseball with 151.Darvish had been 0-2 with a 2.93 ERA in seven starts before pitching 6 2/3 scoreless innings to earn a 3-2 victory over Cincinnati on Sunday.
