With Kate Hudson cheering boyfriend Alex “A-Rod” Rodriguez in the stands, the New York Yankees slugger has been hitting the ball out of the park.

“Sitting on the front row, Kate goes nuts when she watches him play,” says a source who has seen her at Yankees games this summer. “Her excitement and cheering are infectious.” And it shows: The Yanks beat the Toronto Blue Jays 7-5 Tuesday night, their eighth win in nine games.

Last weekend in New York, Rodriguez, 34, hit two home runs in three games against arch rival Boston Red Sox, including a two-run beauty in the bottom of 15th inning late Friday night, the first score of the epic game.

On Saturday, Hudson, 30, brought mother Goldie Hawn and Kurt Russell to the game. The entire family went wild as the Yankees beat the Sox, 5-0. The following night, Rodriquez hit another homer, helping the Yankees win all four games in the series.

It was ladies night Sunday for Hudson, who dropped by NYY Steak at the stadium after the game for drinks with some of the wives – Michelle Damon (Johnny Damon’s wife), Joanna Garcia (Nick Swisher’s girlfriend) and Erin Robertson (David Robertson’s wife). Kate sipped classic martini while eating and chatting with the ladies.

But it’s not just home field advantage. Last Wednesday in Toronto, Hudson sat in a private box at Rogers Centre, watching the Yankees beat the Blue Jays, 8-4.

“After the game, she went underground to wait for A-Rod,” says an eyewitness. “When he arrived, they hopped in his truck and took off together.”

Since their relationship became public in July after they were caught smooching at a Yankees family picnic, Rodriguez has been on top of the world. According to statistics reported by New York’s Daily News, his batting average is around 25 points higher than his season average.

Unlike Tony Romo – who showed poorly as Dallas Cowboys quarterback last season while he was dating Jessica Simpson – Rodriguez has shined like a constellation since Hudson came into his life.

The slugger, who is divorced with two daughters, Natasha, 4, and Ella, 1, has been in good spirits and told reporters Saturday that he feels “freer” and more “liberated” this season.

Rodriguez and Hudson met last November in Miami Beach when a friend introduced them at the grand opening party of the renovated Fontainebleau Resort. “They stood around talking and laughing and seemed to really click,” says a source at the event. “At the time, A-Rod was hanging out with Madonna.”

In the spring and early summer, Hudson, also divorced (and with a son Ryder, 5), has been spotted at Yankees games in New York, Miami and Tampa-St. Petersburg. In Atlanta, she watched his game on TV at Morton’s steakhouse bar while munching on a salad.

“They have their young kids in common, and are really having fun,” says a source.

The Yankees play the Blue Jays again in New York Wednesday at 1 p.m. Then it’s on to Seattle – will Kate be there?
