Today in the Daily Sports Roundup: The Preakness Stakes races at Pimlico, the Astros and Giants have their aces clash, and the WNBA gets their season going.

Meeting up on the diamond . . .

The American League schedule for Saturday has Minnesota at the Yankees, Texas at Toronto, Seattle at Tampa Bay, Cleveland at Baltimore, Boston at Detroit, Oakland at the Angels, and the White Sox at Kansas City. Jake Peavy (2-2, 5.56 ERA) will get the ball for Chicago in that last matchup against the Royals' Luke Hochevar (3-1, 5.65 ERA). Righthander Peavy picked up the win in each of his last two starts for the ChiSox, and he held the Royals scoreless on four hits over seven innings on May 3. Righthander Hochevar beat the White Sox in his May 4 outing, surrendering just one unearned run in his six innings pitched.

Over in the National League on Saturday it'll be Pittsburgh at the Cubs, Philadelphia at Milwaukee, St. Louis at Cincinnati, the Mets at Florida, Arizona at Atlanta, Washington at Colorado, the Dodgers at San Diego, and Houston at San Francisco. The Astros will send ace Roy Oswalt (2-4, 2.63 ERA) to the mound on Saturday to take on Giants ace Tim Lincecum (4-0, 1.86 ERA). Righthander Oswalt had to settle for a no-decision in his last trip to the mound despite holding the Padres to three earned runs in eight innings of work. Righthander Lincecum has given up three or fewer earned runs in each of his seven outings this season.
