Two of the major leagues' best pitchers, Clayton Kershaw and Stephen Strasburg, will face either other for the first time in their careers when the Los Angeles Dodgers and the Washington Nationals begin a three-game series Monday night in Los Angeles. Strasburg, who signed a seven-year contract extension worth $175 million last month, has yet to lose this season. Strasburg also amassed 118 strikeouts, tied for the third most in the majors, while having conceded just 24 walks and 75 hits in 93 innings and allowing opposing batters to hit just.
