Arizona placed five-time Cy Yong Award winner Randy Johnson on the 15-day disabled list on Friday after it was learned he would miss Saturday's scheduled start in Baltimore because of stiffness in his buttocks muscle, which he apparently suffered while playing catch.
The lefty will be replaced on the roster by right-hander Enrique Gonzalez, who was called up from Class AAA Tucson. Right-hander Edgar Gonzalez, who threw 47 pitches in relief on Wednesday in New York, will start Saturday's game for Johnson.
"We'll run a 65-, 70-, 75-pitch count for him depending on how he feels when he goes out there," manager Bob Melvin said of Edgar Gonzalez.
Johnson, 43, started the season on the disabled list while recovering from October back surgery. He is 4-2 with a 3.52 ERA in nine starts with 11 walks and 70 strikeouts. The DL move is retroactive to June 10, the last time he pitched.
His next start could be June 26.
According to Melvin, Johnson began feeling some tightness the past few days while playing catch. He underwent an MRI on Friday. Johnson stayed in Phoenix when the Diamondbacks visited the Yankees Tuesday through Thursday, in part to rest his balky back.
It isn't known if the glut tightness is related to Johnson's back woes.
DIAMONDBACKS 7, ORIOLES 3: The Diamondbacks scored more runs in the eighth inning on Friday than they did during their entire three-game series against the Yankees, erupting for five runs to beat Baltimore at Camden Yards.
Pinch-hitter Orlando Hudson hammered a go-ahead three-run home run to cap a rally from three runs down in the eighth. Hudson did not start after aggravating an ankle injury on Thursday afternoon in New York.
The comeback spoiled a solid start from Orioles lefty Erik Bedard, who left the game two batters into the eighth inning leading 3-1 with a runner on first.
After Orioles reliever Todd Williams walked Mark Reynolds, Diamondbacks manager Bob Melvin called on Hudson, whose home run went 391 feet to right center field. Then in the ninth, Orioles reliever Danys Baez gave up two more runs when Augie Ojeda, who started in place of Hudson at second base, homered in his first game in the big leagues since Oct. 2, 2004.
--LHP Randy Johnson is going to be handled delicately by management and the coaching staff when it comes to monitoring his health. He was placed on the 15-day disabled list, retroactive to June 10, with tightness in his glut.
"We are going to err on the side of caution," manager Bob Melvin said. "I said that from Day 1. That's how we're going to handle it. We're not going to run him out there in a situation where it could get worse."
--INF Augie Ojeda, whose contract was selected from Class AAA Tucson, joined the Diamondbacks and started at second base for Orlando Hudson on Friday in Baltimore, his first time back in the majors since 2004. Ojeda, 32, went 2 for 4 with a two-run homer.
--A reporter for the Associated Press published a detailed scouting report Arizona had on Yankees hitters when he found the sheet lying on the floor of the Diamondbacks' dugout. Manager Bob Melvin didn't sound upset that the information became public.
"If someone goes inside (the clubhouse) and takes something..." Melvin said. "But if one of our players has a cheat sheet and it's left out there, I don't see a problem with that. If they find it, they find it. ... You can probably find those scouting reports in everybody's dugout."
--RHP Mike Schultz was designated for assignment to clear room on the 40-man roster for infielder Augie Ojeda.
--2B Orlando Hudson did not start Friday's game against the Orioles after jamming his left ankle Thursday against the Yankees. He hit a pinch-hit, three-run homer Friday against Baltimore.
BY THE NUMBERS: 31 -- OF Eric Byrnes' streak of reaching base in consecutive games via a hit or a walk, which he did from May 5 to June 9, tied Matt Williams' streak from 1999-2000 for fourth place in club history.
LHP Randy Johnson (tightness in buttocks muscle) was placed on the disabled list June 15, retroactive to June 10.
2B Orlando Hudson (jammed left ankle) left the June 14 game. He didn't start the June 15 but hit a home run as a pinch hitter.
LHP Doug Slaten (sore right wrist) was struck by a ball before the June 12 game, and he didn't pitch June 12-13. He returned to action June 14.
3B Chad Tracy (rib cage strain) went on the disabled list on May 16. He was activated June 10 and was in the starting lineup against Boston.
OF Jeff DaVanon (left ankle, right shoulder surgery) opened the season on the disabled list. He was still bothered by a sore right shoulder in early June, and there was no timetable for his return.
