Bones Leaves Reds Aching : Baseball: Pitcher makes his major league debut a big one by defeating Cincinnati, 13-0.

Ricky Bones was a trifle nervous when he made his major league debut Sunday, but not for long.

Once Bones breezed through the first inning and Bip Roberts hit a lead-off home run, everything fell into place for the 22-year-old Puerto Rican. He and Roberts led the Padres, who humiliated the Cincinnati Reds, 13-0, in front of 17,889 at San Diego Jack Murphy Stadium.

Bones was just in from Las Vegas, where he was 8-6 and had a 4.22 earned run average. He hardly could have broken in more impressively. He blanked the Reds on two hits through seven innings and didn’t permit a runner to pass first base.

“It was just a dream being here,” Bones said. “I slept well last night, but my mind was on the game. I kept waking up every hour. I was shaky at first, then I was O.K. I was ahead in the count, and I made good pitches.”

Although Roberts’ first-inning home run--hit on Kip Gross’ first pitch--would have been enough to give Bones his first victory, Roberts didn’t rest his case with it. He hit another homer--also off Gross and also on the first pitch--in the fourth inning. He was four-for-four, raising his average eight points to .284.

Roberts had complained last week about being taken out of a game by Manager Greg Riddoch when he was only slightly injured, but he vowed not to let that happen again.

“Everything I want to do now will be positive,” Roberts said. “Everything will be confined to the field. I don’t usually pop off in the newspapers.”

Roberts, whose four runs scored tied a club record, said something he observed Saturday night led to his second four-hit game of the season.

“(Jose) Rijo was throwing me a lot of breaking balls, so I was looking for a slider right away, and I got it,” Roberts said. “I figured it was out when I hit it. The other one was on a slider, too, but I thought (Glenn) Braggs was going to catch it. It barely missed his glove.”

Roberts’ two home runs were among five hit by the Padres, which set a club record for a nine-inning game. Darrin Jackson, Tony Fernandez and pinch-hitter Thomas Howard also hit homers, all off rookie Gino Minutelli.

All five home runs went to left field, and they were the Padres’ first five in seven games. The Padres also hit five against the San Francisco Giants on May 23, 1970, but that splurge came in a 15-inning game.

With the victory, the Padres moved a fraction of a percentage point ahead of the Reds into fourth place in the National League West and climbed to 7 1/2 games behind the Dodgers.

Riddoch took note: “It’s that time of year when you’re watching the scoreboard all day long. It would be great to see the Reds smoke the Dodgers in L.A. and make it a four- or five-team race. It would be great to be a part of something like that.”

Sunday’s shutout was the Reds’ second consecutive against the Padres and the third in five games. It pushed the Reds three games under .500.

Manager Lou Piniella somehow avoided saying anything negative, but Rijo was less charitable.

“It’s hard to comprehend this situation, but when you see it, you believe it. I see a losing team,” Rijo said. “I see a team giving up with two months to go.”

Second baseman Bill Doran also admitted that things were amiss. “This is as bad as it’s been in the year I’ve been here,” he said. “If everybody shows no pride, that would disappoint me more than what’s taking place on the field.”

The Padres one-run lead grew to 3-0 in the third when Jack Howell singled in two runs, and to 4-0 in the fourth when Roberts hit his second home run. When Minutelli took over in the fifth, the Padres backed Bones with three-run homers by Jackson and Fernandez.

“Everybody likes to pitch with a 10-run lead,” Bones said. “I had a lot of confidence after that. I kept the ball low, and I had a good sinker and slider.”

Bones threw 106 pitches, 67 of them strikes, and Riddoch thought that was enough in such a lopsided game. Jim Lewis, another recent arrival from Las Vegas, and Rich Rodriguez each pitched for an inning to complete the shutout.
