SAN DIEGO -- Cory Luebke will miss at least one start after experiencing soreness in his left elbow in the fourth inning of his start Friday against the Giants at AT&T Park.
Luebke won't go on the disabled list, though it's unclear when he will reappear in the starting rotation.
Jeff Suppan, 37, will be officially added to the 25- and 40-man roster before he starts Wednesday for the Padres against one of his former teams, the Brewers.
"We're going to push Cory back a few days. We're being a little cautious," Padres manager Bud Black said before Tuesday's game. "He's feeling much better. We are feeling confident that this will be just one start."
Luebke said he first noticed the tightness during his start against the Giants. He allowed two runs over six innings on his way to his third victory of the season. Luebke (3-1) has a 2.61 ERA over his five starts and has been one of the few bright spots for the 7-17 Padres.
"It's early [in the season] so we're trying to stay on top of it," Luebke said. "I've been lucky in that I have never had anything wrong with my arm. Hopefully, this will be the last of it."
In March, Luebke signed a contract extension that guarantees him $12 million and could earn him as much as $27.75 million and could keep him with the team through 2017.
Luebke has been receiving treatment on the elbow from the training staff since late Friday and said he was encouraged with the way it was feeling Tuesday afternoon.
"It feels significantly better than it felt Friday," Luebke said.
Suppan set for big league return Wednesday
SAN DIEGO -- Jeff Suppan found it mildly amusing Tuesday when he was reminded that the start that he will be making Wednesday for the Padres comes against the Brewers, a team he spent four seasons with from 2007-10.
"I'm trying to go about it as if it's business as usual," Suppan said. "That's probably something I will think about after."
Suppan, 37, will make his first Major League start since Oct. 3, 2010 on Wednesday as he replaces Cory Luebke, who is dealing with a sore left elbow.
The Padres will make an official roster move before Wednesday's game to add Suppan to the 25- and 40-man roster. The likely move would be moving outfielder Kyle Blanks (shoulder surgery) from the 15-day disabled list to the 60-day DL.
Suppan signed a Minor League contract with the team right before Spring Training and had a 5.87 ERA in three appearances before being sidelined with a strained right triceps. He made two starts in extended spring workouts in Arizona followed by two more starts with Triple-A Tucson, where he had a 12.15 ERA in 6 2/3 innings.
San Diego manager Bud Black said Suppan is to the point where he can throw upwards of 90 pitches on Wednesday.
"I've always been the type of pitcher who goes pitch to pitch," Suppan said. "I got up to 65 [in Tucson] and I feel good, my injury [triceps] feels good."
Suppan has a career record of 138-143 and an ERA of 4.69 in 16 Major League seasons with the Royals, Cardinals, Red Sox, Brewers, D-backs and Pirates. He spent the entire 2011 season pitching in Omaha, the Royals' Triple-A affiliate.
Padres ready to leave gloomy April behind
SAN DIEGO -- So long, April. Good riddance.
With a loss to the Brewers on Monday, the Padres wrapped up a disappointing month of April as the team finished the first full month of the regular season with a 7-17 record.
The 7-17 starts ties the 1994 team for the worst April in franchise history. The Padres were 9-17 a year ago in April after winning the only game they played in March. That team went on to finish 71-91.
The Padres did finish April with a 3.53 team ERA, limiting opposing batters to a .224 average.
