DENVER (AP) -- Jeff Cirillo's single with two outs in the 10th inning scored Tom Goodwin with the winning run as the Colorado Rockies beat the Oakland Athletics 10-9 Monday night to snap an 11-game losing streak and split a day-night doubleheader.

Goodwin drew a two-out walk off Jason Isringhausen, who then walked Brian Hunter. Scott Service replaced Isringhausen and Cirillo hit a liner to left-center to bring home Goodwin.

	Olmedo Saenz had three hits and four RBI in Oakland's 11-10 win over Colorado in the opener.

The Rockies tied it in the ninth when Cirillo, Todd Helton and Todd Walker hit consecutive singles off Isringhausen.

Isringhausen (4-3), who blew his fourth save after earning his 20th in the opener, escaped further damage by striking out pinch-hitter Jeffrey Hammonds and getting Ben Petrick to ground out.

Jason Giambi's two-out two-run single in the ninth gave Oakland a short-lived 9-8 lead.

The Athletics trailed 8-7 when Terrence Long reached on an infield single and Randy Velarde singled off Gabe White. Both runners moved up on a passed ball by Petrick and Giambi sent a 1-1 pitch past second baseman Todd Walker, scoring Long and Velarde.

Colorado rallied from a 7-6 deficit on Neifi Perez's two-out, two-run double in the eighth inning after Oakland went ahead in the top half on Miguel Tejada's two-out, three-run home run.

The Rockies, who trailed 4-0, were held hitless for 5 1/3 innings by Ariel Prieto before Mike Lansing tripled off the center-field wall. Two batters later, Prieto lost his shutout on Hunter's RBI single. Helton singled to left to score Hunter to cut the lead to 4-2.

Colorado went in front 6-4 when Goodwin broke out of a 3-for-28 slump with a seventh-inning grand slam -- his second of the season.

The Athletics took a 2-0 lead in the first on Jason Giambi's RBI double and Matt Stairs' run-scoring single.

Long homered off the upper deck facade in right field leading off the third and Ben Grieve gave Oakland a 4-0 lead with his 17th to start the sixth.

In Game 1, Olmedo Saenz had three hits, including a double and home run, and four RBI, and Jeremy Giambi added a two-run homer as the A's beat Colorado 11-10.

Adam Piatt went 2-for-4 with two RBI for the A's, who won for only the second time in six games at Coors Field.

"I'm telling you Saenz was born to hit," Howe said. "I tell you, he's going to hit."

The third baseman, a .310 hitter against the AL, has hit .411 in 12 games against the NL.

"I didn't know that," said Saenz, who came into Monday hitting 12-for-30 with two home runs and five RBI. "I just want to do what I can to stay in the big leagues."

Mike Magnante (1-1) earned the win with 1 1/3 innings of one-run ball, and Isringhausen, who surrendered a two-run homer to Helton -- who also hit a solo shot off Magnante in the seventh -- got the final three outs.

Larry Walker drove in three runs with a single and home run for Colorado and reached the 1,500-hit plateau. Hunter hit his first home run and had two RBI, and Cirillo drove in two runs for the Rockies.

The Athletics staked Marcus Jones, making his major league debut, to a 4-0 lead in the first inning on two-run homers by Saenz and Giambi. Hunter's first home run since July 27, 1999, came in bottom half.

Oakland chased Rigo Beltran, called up from Triple-A Colorado Springs, in the second inning. Velarde singled to left and scored on Jason Giambi's double inside the bag at first. After Saenz walked, Julian Tavarez replaced Beltran and allowed a bloop RBI single to Piatt.

Walker's sixth home run of the year, a two-run shot into the third deck in right field off Doug Jones, keyed a three-run fourth. Petrick singled, moved to second when Jones threw away an attempted bunt by Tavarez, and scored when Hunter's pop fly dropped in front of center fielder Ryan Christenson for a double.

Walker hit Jones' first pitch to him into the seats in right to give the Rockies a 7-6 lead.

Successive one-out doubles by Jason Giambi, Saenz and Piatt off White (6-1), and an RBI double by Ramon Hernandez off DeJean in the seventh put the Athletics back in front, 9-7.
