NEW YORK (AP) — Jonathon Niese struck out a career-high 10 in six scoreless innings and the New York Mets shut down the slumping St. Louis Cardinals for the third straight game, getting a homer and three RBIs from rookie Kirk Nieuwenhuis in a 6-1 victory Sunday night. Andres Torres added a two-run triple and finished a homer shy of the cycle. Nieuwenhuis, batting leadoff, also had three hits. Niese (4-2) became the latest New York pitcher to dominate the Cardinals, following Johan Santana’s no-hitter in the series opener Friday night — the first in Mets history — and knuckleballer R.A. Dickey’s seven-hit shutout Saturday. The only thing that prevented the Cardinals from being blanked in three consecutive games for the first time since October 1976 was a two-out RBI single by Adron Chambers in the eighth off Elvin Ramirez, who was making his major league debut.

WEST DES MOINES, Iowa (AP) — Jay Haas finished with a 16-under 197 total to win the Principal Charity Classic by five strokes on Sunday, becoming the first golfer to win the Champions Tour event in Iowa three times. Haas, the winner at Glen Oaks Country Club in 2007 and 2008, led by three shots heading into Sunday and made it stand up with a final round 5-under 66. Haas’s 16-under tied the tournament mark set by Gil Morgan in 2006 and matched the largest victory of the season in the Champions Tour. Kirk Triplett set the course record with a 9-under 62 and finished second at 11-under 202 along with Larry Mize.

(AP) — Shawn Johnson is calling it a career, ending her attempts at making a second Olympic team because of a lingering knee injury.  The Olympic gold medalist and 2007 world champion announced her retirement Sunday, four days before the start of the U.S. gymnastics championships. Johnson says her left knee, injured in a January 2010 ski accident, continued to slow her down, and she worried about the long-term damage if she kept competing.

The 20-year-old from West Des Moines, Iowa, was one of the biggest stars at the Beijing Olympics. Along with her gold on balance beam, she won silvers in the all-around, team competition and floor exercise. At the 2007 world championships, Johnson won the all-around, led the Americans to their third team title and took gold on floor.
