BALTIMORE, AUG. 8 -- Shortly after Alan Wiggins returned to the Orioles and Scott McGregor departed again, the Orioles lost an ugly, 11-5 game to the Texas Rangers tonight before 34,883 at Memorial Stadium.

Homers by Ruben Sierra, Oddibe McDowell and former Oriole Tom O'Malley were more than enough for the Rangers as Baltimore set a season high with 14 runners left on base.

For the Orioles, the only memorable thing tonight was the second consecutive two-homer game by Larry Sheets. Sheets has four two-homer games this season and 22 homers total.

Otherwise, futility prevailed. It was a game with two hit batsmen, a passed ball, a wild pitch and 13 walks between the two teams.

Luckily, the fans had a fireworks display afterward for entertainment.

Winner Bobby Witt (6-5) pitched five innings and Mitch Williams earned his second save in 11 opportunities. Mike Boddicker (7-6) took the loss.

In Boddicker's last 11 starts, he is 2-5 with a 5.31 ERA, raising his season's ERA to 3.82.

"He had some bad periods," Orioles Manager Cal Ripken Sr. said. "He just wasn't consistent. He had times when he had good rhythm and control and other times, no. He struggled with his rhythm more than anything else."

Ripken said Boddicker's problems stemmed from his recent back problems. "You see, it takes a long time to get control and rhythm. It doesn't take that long to get out of shape. Boddicker relies on control, mixing his pitches. When he doesn't have that, he has problems," Ripken said.

Sierra got his 22nd homer of the season in the first, on a 2-0 pitch, to put Texas in front by 1-0.

In the second, the Rangers got two more, helped by an error by third baseman Ray Knight. Geno Petralli got an RBI when he was hit by a pitch and Texas made it 3-0 on O'Malley's double-play grounder.

Sheets made it 3-1 in the second with a homer to right field, but Texas broke it open in the sixth. O'Malley hit a three-run homer, only his second major league homer. Both have come in Baltimore. His other came last year (June 19) for the Orioles, against Detroit.

Boddicker had intentionally walked Petralli with two down to get to O'Malley. "That doesn't show much respect for the hitter behind him, but that's something the pitcher has to do," O'Malley said.

Baltimore scored single runs in the sixth and seventh off reliever Steve Howe, making his second appearance in as many nights since being called up from the minors.

Knight's double scored Fred Lynn in the seventh to make it 6-3, but Texas scored five runs in the eighth.

Sheets got his second homer in the ninth.

Orioles Notes:

McGregor, suffering from a stiff left shoulder because of tendinitis, was placed on the 15-day disabled list, retroactive to Wednesday. McGregor, scheduled as the Sunday starting pitcher, has a 2-7 record with a 6.83 ERA. Eric Bell will start Sunday.

To replace McGregor, the Orioles recalled left-handed reliever Jack O'Connor from Class AAA Rochester. O'Connor, 29, was 0-1 with a 7.31 ERA in 12 games during an earlier stint with the Orioles this season. He was sent to Rochester July 10.

"I think it's more that I'm 2-7 than my shoulder," McGregor said of the move. "I just thought it would take a few days to work out, but they wanted me on this two-week program. It's tough, because this happens just as I was starting to throw well."
