CHICAGO -- Outfielder Cameron Maybin wasn't in Sunday's starting lineup and was likely unavailable to hit in the final game of the Padres' three-game series against the White Sox.
Maybin left Saturday's 4-2 victory with tightness in his right calf. According to manager Bud Black, it has been bothering him in recent days.
"Cam is doing a little better, but he's still a little sore," Black said. "So we're going to try and be cautious with this."
Maybin -- who was replaced Saturday by Chris Denorfia -- would have certainly been in Sunday's lineup against White Sox left-handed pitcher Chris Sale.
Maybin missed the first 25 games of the season while recovering from a ruptured left biceps tendon he injured making a diving catch in a Spring Training game in March.
Since returning from the disabled list on April 27, Maybin is hitting .303 with one home run. He hit that homer in a victory over the White Sox on Friday.
Will Venable got the start in center field on Sunday, a day after he tied his career high with four hits.
Padres mulling starter options for Tuesday
CHICAGO -- The Padres know that pitcher Tim Stauffer will start against the Pirates on Monday when the team returns to Petco Park.
The team also knows who will start Wednesday's game, Ian Kennedy.
What remains a mystery is who the team will tab to start Tuesday's game, the first time it has needed a fifth starter in a while.
With Andrew Cashner and Robbie Erlin on the disabled list, the Padres have leaned on Sunday starter Eric Stults, Stauffer, Kennedy and Tyson Ross. But they'll need a starter on Tuesday.
"The starter will come from within our organization," quipped manager Bud Black, who was not yet ready to divulge Tuesday's starter.
The candidates that make the most sense for the Padres are right-hander Odrisamer Despaigne, who is currently with Triple-A El Paso, and righty Jesse Hahn, who is with Double-A San Antonio.
Despaigne threw four innings on Tuesday in his Triple-A debut. Matt Wisler, who would have been another candidate, started Sunday for El Paso.
As for Hahn, who impressed the organization in Spring Training and made a late push for a spot on the Opening Day roster, Tuesday would be his normal day to start.
Hahn, 24, is 2-1 with a 2.20 ERA in 32 2/3 innings in the Texas League. He has allowed 29 hits, 11 walks and had 28 strikeouts. Opponents are hitting .242 against him.
Alonso finding groove at plate after slow start
CHICAGO -- On Friday, Yonder Alonso hit a two-run home run against the White Sox. On Saturday, he just about did the same thing, flying out to the warning track in right field in the eighth inning.
"I'm evolving a bit as a hitter," Alonso said. "Maybe some of those line drives are going out of the park."
Alonso has hit two home runs on this road trip and has three in his last nine games. He knows his game is still using all field and hitting doubles -- he had 39 of them in 2012.
At this point, Alonso is just happy to see some of his hits find anything but gloves. After a slow start, he believes he has found something -- something successful -- with his swing.
Alonso, who is hitting .211, has eight multi-hit performances during this 21-game stretch after he had two such games during his first 35 games this season.
"I think it was just a matter of time … and I was saying that in April," Alonso said. "It was just a matter of time before things got better. I kept hitting balls right at people. I just had to stay with it and trust what I was doing.
"I know the type of hitter I am. I know the player I'm going to be. I've always heard that if you're a good hitter, you're going to hit balls right at people."
