MIAMI (AP) Jason Jennings became the winningest rookie in Colorado history and Todd Helton hit an RBI double as the Rockies beat A.J. Burnett and the Florida Marlins 1-0 Monday night.

Burnett (11-9) lost despite pitching a four-hitter and striking out nine. He leads the NL with six complete games.

Jennings (13-5) surpassed Armando Reynoso's franchise record of 12 wins by a rookie in 1993.

Both teams received quality pitching after being roughed up in their two previous games. The Rockies gave up 27 runs in losses to the Chicago Cubs, while the Marlins allowed 18 runs in losing to Arizona.

The only run scored in the fourth. Larry Walker drew a one-out walk and scored on Helton's double to left field.

Jose Jimenez pitched the ninth to earn his 31st save in 34 chances. He got Luis Castillo on a grounder with a runner on third to end it.

Jennings won his third straight start. He worked 5 2-3 innings, allowing four hits while striking out five.

Jennings was lifted after the Marlins loaded the bases in the sixth. Justin Speier relieved and retired Eric Owens on a popup.

Burnett dropped his second start in a row after winning three straight.

Helton hit a pair of doubles, but also was twice thrown out on the bases.

In the second inning, Helton was cut down by right fielder Juan Encarnacion while trying to advance to third on a fly ball.

In the fourth, Helton was thrown out by Owens when he tried to score from second on Sandy Alomar's single to left field.
