CHICAGO(AP) -- In spring training, Randy Wells never imagined
being the Cubs' first 10-game winner this season.

Well, he is.

Wells became the first rookie in 11 years to reach 10 wins with
another strong outing against the Houston Astros, and Milton
Bradley homered in Chicago's 4-1 victory Tuesday night.

Wells, who has more win than Carlos Zambrano, Ryan Dempster, Ted
Lilly and Rich Harden, didn't even start pitching for the Cubs
until May 8 when he was recalled from Triple-A Iowa.

"I would've said that would be great, realistically I probably
would've laughed at you. It's nice and rewarding, I can't lie,"
Wells said. "Just thinking at my career, my past and the road I
took to get here it's nice to be recognized."

In his previous two starts against Houston, Wells (10-7) pitched
14 scoreless innings. On Tuesday, the 26-year old right-hander
allowed just one unearned run and seven hits in 6 2-3 innings,
striking out four and walking two.

Kerry Wood was the last Cubs rookie to win 10 games, in 1998.
Wells is Chicago's first 10-game winner this season.

"I don't where we would be without (Wells)," Bradley said.

Cubs reliever John Grabow and Kevin Gregg each got two outs and
closer Carlos Marmol pitched a scoreless ninth for his seventh
save in 11 chances.

Tom Ricketts, who led the $845 million purchase bid for the Cubs
and is expected to assume the most active ownership role in the
family, watched the game from front row seats near the Chicago
dugout. Ricketts stood up and clapped after Bradley's home run.

"I saw him down there," said Cubs manager Lou Piniella, who met
him for the first time. "I shook his hand after the ballgame and
I said, 'Hopefully that's the first of many, many more for you.'
That was it."

Michael Bourn had three hits for the Astros, who have lost seven
of their last nine games.

Aaron Boone was activated off the disabled list Tuesday, five
month after the 36-year-old third baseman had open-heart surgery

"It's good to be in this position and back here after all that
has gone through in my life this year. I'm excited about it," he
said.

Astros manager Cecil Cooper said he will try to play Boone as
soon as possible.

Bradley put the Cubs ahead with a solo shot off Astros starter
Brian Moehler in the fourth inning. It was his 12th of the
season.

Alfonso Soriano, back after missing three games with a sore
knee, singled with one out in the fifth then Jeff Baker hit what
Appeared to be an inning-ending double play, but shortstop
Miguel Tejada made an errant throw to second, allowing Soriano
to advance to third. Koyie Hill followed with an RBI single.

"We didn't play particularly well on the defensive side. That's
basically it. I thought Moehler threw the ball fine except for
the home run ball," Cooper said. "Other than that, he'd probably
still be pitching in the game 1-0. That's what I told him. I
thought he deserved a better fate."

Moehler didn't get much help from his defense in the sixth
inning either. After a leadoff single by Bradley, right fielder
Hunter Pence dropped Derrek Lee's flyball on the warning track.
Bradley went into third and Lee ended up at second on the error.
Aramis Ramirez followed with a single to score Bradley and put
the Cubs up 3-0.

"Moehler pitched unbelievable. He pitched great. That's a good
lineup. He battled for us," Pence said. "I got to get better. I
got to make that play for him and it hurts to do that to him
when he does that for you. And what can you do? It feels bad to
let him down."

Moehler (8-10) allowed three runs, two earned on six hits in 5
1-3 innings.

Kaz Matsui singled in the seventh inning, then stole second and
was able to advance to third when Baker dropped the ball while
covering second base. Matsui scored on Chris Coste's groundout.

With runners on first and third with one out in the eighth,
Kosuke Fukudome lined an RBI double down the right-field line.
Ramirez attempted to score from first but was easily thrown out
at the plate.
