CHICAGO, JULY 7 -- The Baltimore Orioles tonight ended a run of frustration against the Chicago White Sox that dates back to last season.

With John Mitchell pitching effectively for eight innings and a quartet of players getting two hits apiece, the Orioles defeated the White Sox, 4-1, before 32,151 fans at Comiskey Park.

It was Baltimore's first victory over Chicago in nine games, six this season. But because the Oakland Athletics lost to Cleveland, the White Sox remained in first place in the American League West by percentage points.

Mitchell (1-2), who earned his first major league victory since Aug. 5, 1987 (when he was with the New York Mets), allowed seven hits and two walks. He faced a total of 20 batters during his final six innings -- two over the minimum. Gregg Olson pitched a one-two-three inning for his 16th save in 18 opportunities.

Tim Hulett, Mike Devereaux, Joe Orsulak and Bill Ripken each had two hits for the Orioles, who entered the game batting .180 against the White Sox this season.

Hulett keyed a three-run fourth inning with a two-run triple, his first triple since 1986 when he was with the White Sox.

Greg Hibbard (6-5) allowed three runs on seven hits in four-plus innings.

The White Sox took a 1-0 lead in the first on an infield single, a walk -- and after a visit to Mitchell by pitching coach Al Jackson when he went to 2-and-0 on Carlton Fisk -- a fielder's choice and a sacrifice fly.

The Orioles left runners on first and third in the third, but they moved in front with three runs in the fourth.

Mickey Tettleton, one for his previous 17 and nine for 48, led off with a double to deep right-center that came within inches of being his first home run since June 23.

Cal Ripken walked. With the count to Hulett 1-0, Manager Frank Robinson called for the hit-and-run. Hibbard's pitch was eye-high and on the outside part of the plate, but Hulett drove it to right-center -- well beyond the reach of right fielder Sammy Sosa, playing shallow.

Bob Melvin flied to Sosa medium deep and Hulett scored as the throw was high and up the first base line. Bill Ripken singled, but a great catch by Lance Johnson on a drive by Mike Devereaux to deep left-center prevented further damage.

The Orioles made it 4-1 in the sixth against Adam Peterson, who worked five otherwise strong innings. With two out, Brad Komminsk singled for his second hit in his last 27 at-bats. Bill Ripken walked, and Devereaux scored Komminsk with a single to left.

"I don't think he realizes how good his stuff is," Robinson said of Mitchell. "His stuff is good enough for him to win up here and for him to have confidence in it."

Mitchell is most effective when he keeps the ball down. He did not do that in his last start, Monday night against the Rangers, when he lasted just two-plus innings. Tonight, he got 16 outs on ground balls, making it a busy night for shortstop Cal Ripken and second baseman Billy Ripken. The brothers handled 21 chances.

"I'd love to be a strikeout pitcher, but I'm not," Mitchell said. "And if I get too many fly balls, they start going out of the ballpark."

Orioles Notes: Orioles President Larry Lucchino, General Manager Roland Hemond, Assistant General Manager Doug Melvin and Robinson will meet here Monday to discuss some player moves.

"We'll be talking about what we have to do to be better in the second half of the season," Robinson said after tonight's game. "We'll go over the ballclub."

In a telephone interview, Melvin said the discussions will cover the progress of youngsters like recently recalled pitcher Curt Schilling and how the club will accommodate the coming reactivations of injured outfielders Brady Anderson and Phil Bradley and pitcher Joe Price. Robinson said the club's starting pitching situation also will be evaluated. That could mean discussing Ben McDonald and Jeff Ballard, among others.

Melvin said Hemond has been working the phone to check on various trade possibilities while Gordon Goldsberry and Fred Uhlman Sr., special assistants to the general manager, have been out scouting other teams. Hemond also scouted a recent Phillies-Astros series.

Asked about New York newspaper reports that the club had been talking with the Mets about outfielder Mike Marshall, Melvin said the Orioles had scouted the Mets but "not particularly to see Mike Marshall. "We've got people seeing everybody."
