BALTIMORE -- Marlon Byrd and Travis Metcalf each belted grand slams Wednesday, helping the Texas Rangers set a modern-record for most runs in a game by decimating the Baltimore Orioles 30-3, in the front end of a twi-night doubleheader at Camden Yards.

It was the ninth time a major league team scored 30 runs, the first since the Chicago Colts set the major league scoring record in a 36-7 rout of the Louisville Colonels on June 28, 1897.

The three-game series was scheduled to begin Monday, but the opener was rained out and rescheduled for Wednesday.

Jarrod Saltalamacchia homered twice and drove in a career-high seven runs, and Ramon Vazquez also added a pair of long balls and a career-best seven RBI for Texas, which pounded out 29 hits in the contest to snap a two-game skid. Kason Gabbard (6-1) earned the win, allowing three runs and seven hits, while walking one and fanning three over six frames.

Brian Roberts went 3-for-5 and scored twice for Baltimore, which has lost three of its last five. Daniel Cabrera (9-13) was shelled for six runs and nine hits over five innings in the loss.

The lopsided score also came just hours after the Orioles announced manager Dave Trembley will return to the team for the 2008 season, with an option for 2009.

Trembley was initially promoted from his position as bullpen coach to manager on June 18, replacing the dismissed Sam Perlozzo. Baltimore has since gone 29-26 under Trembley, who spent 20 years as a manager in the minor leagues.

Trailing by three, Texas answered by posting a five-spot in the fourth to take the lead for good. Saltalamacchia's bases-loaded single to center scored two runs, before Vazquez followed by clubbing a three-run homer to right that put the Rangers on top.

Another outburst in the sixth -- highlighted by Byrd's slam -- put the game away. Saltalamacchia led off with a homer to center, chasing Cabrera, and Vazquez greeted reliever Brian Burres with a base hit to right. A wild pitch sent him to second, Frank Catalanotto walked and a fielder's choice bunt by Ian Kinsler erased the lead runner before Michael Young's single loaded the bases.

Byrd followed by blasting an 0-1 pitch well over the fence in left for a grand slam, and after a pair of two-out singles, Saltalamacchia knocked in another run with a base hit through the left side. Vazquez singled in another run, and Catalanotto's RBI single chased Burres. Kinsler's hit off Rob Bell plated Vazquez to make it 14-3.

Catalanotto and Kinsler each knocked in a run in a the eighth to continue the rout, before Metcalf's grand slam to left -- the first of his big league career - made it 20-3. An RBI single by David Murphy, and a three-run shot from Saltalamacchia polished off the 10-run frame.

Jason Botts added a two-run double and Murphy knocked in a run in the ninth before Vazquez's three-run homer -- his second long ball of the game -- finally capped the scoring.

Baltimore pushed a run across in the first behind a leadoff double from Roberts and a run-scoring single by Corey Patterson. The O's also added two more in the third on a ground-rule double by Nick Markakis and an RBI single by Miguel Tejada that made it 3-0.
