Carlos Quentin tweaked his groin running the bases in Sunday's loss to the Rockies and is considered day-to-day.

The oft-injured outfielder is likely to miss a game or two while the injury heals, but it doesn't appear he will require a trip to the disabled list.

Padres activated OF Carlos Quentin from the 15-day disabled list.

Quentin missed the first six weeks of the 2014 regular season with a knee injury. He didn't hit very well on his minor league rehab assignment but has excellent career numbers away from Petco Park and is worth rostering in most standard mixed fantasy leagues.

Carlos Quentin (knee) is likely to be activated Tuesday.

Quentin is traveling to Cincinnati on Monday to meet up with the Padres after sitting out the first six weeks of the 2014 regular season because of a knee injury. He was just 3-for-18 (.167) on his minor league rehab assignment but is worth rostering in most mixed fantasy leagues. The oft-injured outfielder has an .855 OPS in his last 286 major league games.

Carlos Quentin (knee) went 2-for-4 and belted his first home run on his minor league rehab assignment at Triple-A El Paso on Friday.

Quentin started in left field in the game and improved to 3-for-14 (.214) on his rehab assignment. He's expected to rejoin the Padres at some point next week.

Carlos Quentin (knee) will begin a minor league rehab assignment with High-A Lake Elsinore on Saturday.

He will need three or four games before being ready to return to the Padres lineup. While he is a terrible bet to remain healthy and in the lineup for the Padres, fantasy owners should take advantage of his power while he is on the field.

Carlos Quentin (knee) could begin a rehab assignment over the weekend if he continues to progress.

Quentin has been doing baseball activities -- running, taking batting practice, shagging fly balls -- in Arizona in recent days, and the next step is a rehab assignment. He'll travel to San Diego tomorrow to find out if he's ready. If so, he'll start at High-A Lake Elsinore. A return in early-to-mid May appears to be in the cards.

Carlos Quentin (knee) will run, take batting practice and shag fly balls at the Padres' spring training complex Monday.

Quentin has recovered pretty slowly after injuring his left knee late in spring training, but it appears he's close to beginning a rehab assignment. The veteran outfielder seems to be on track for a return around the middle of May.

Carlos Quentin (knee) took batting practice on Monday.

Quentin had hit in the indoor cages for the previous five days, but this was the first time he's hit on the field. "It's a good first step for him," said Padres manager Bud Black. "When this happens, then it's a good sign for Carlos and the club." Quentin still needs to do some running and increase the intensity of his workouts before he'll be cleared for a rehab assignment. It seems unlikely that he'll be ready before the end of April.

Carlos Quentin (knee) has been taking swings in the cages, and could be cleared for live batting practice as early as next week.

The veteran slugger is making slow progress in his recovery from a left knee injury. At this point, it's unlikely to expect a return before the end of April.

Padres manager Bud Black announced Sunday that Carlos Quentin (knee) will last beyond the minimum 15 days.

The earliest date that he's eligible to return would've been April 9, but it now appears that it will be at least mid-April before he returns to the Padres lineup. He's been no stranger to the disabled list in his career, and remains very difficult to trust in all fantasy formats.

Padres placed OF Carlos Quentin on the 15-day disabled list with a left knee injury.

Knee problems continue to plague Quentin, who appeared in just 86 games in 2012 and 82 games in 2013. He's still a decent fantasy stash because of his power potential, but there is no timetable yet for his 2014 debut.

Padres manager Bud Black said Friday that Carlos Quentin (knee) could begin the season on the disabled list.

Quentin is dealing with some soreness in his left knee, which is actually his "good" knee. The Padres open up the season Sunday night, so a decision on the outfielder's status will have to be made soon. Quentin has averaged just 84 games played in his two years with the Padres.

Carlos Quentin (knee) was a late scratch from Wednesday's Cactus League game.

Quentin is dealing with a bit of soreness in his left knee, and the Padres saw no reason to push it this late in spring. It's not the same knee that Quentin had surgery on in September. Quentin will be re-evaluated on Friday, but at this point it doesn't seem like the kind of thing that will threaten his spot as an Opening Day starter.

Carlos Quentin went 1-for-2 with a solo home run on Tuesday against the D'Backs.

Quentin victimized Randall Delgado in the second inning, debuting in the Cactus League in style. The outfielder underwent knee surgery in September, but he is hoping to cross the 500 plate appearance plateau for the first time since 2010.

Carlos Quentin (knee) will make his Cactus League debut on Tuesday.

The Padres have brought Quentin along slowly this spring following last September's right knee surgery, which was his third operation on the knee in 18 months. Quentin has said that he's feeling much better now than when he reported to spring training last year, but the injury-prone veteran outfielder is always going to be a poor bet to stay healthy.

Padres manager Bud Black said Sunday that Carlos Quentin's (knee) Cactus League debut is "right around the corner, in a couple days."

Quentin had right knee surgery in September, which was his third operation on the knee in 18 months. However, he said last month that he's feeling much better now than when he reported to spring training last year. As always, he's a poor bet to stay healthy this season.

Carlos Quentin said Wednesday that his right knee feels much better now that it did heading into spring training last year.

Quentin had an operation on the knee in September, which was his third in 18 months. The outfielder has played in just 168 games over the last two seasons and is always going to be a health risk, but he believes the latest surgery combined with a more upright batting stance will give him a better shot to stay on the field.

Carlos Quentin said that he feels "a lot better" about surgery this past week on his right knee than he did about the previous two operations on the knee.

Quentin said he already "feels so much better" and thinks the operation, as well as "my new standing taller stance" will make a difference for him going forward. "I didn't realize how much torque I was putting on my right knee with my old stance from the squat," the outfielder added. "I'd swing without moving my right foot, which transferred everything to the knee."

Carlos Quentin underwent surgery Tuesday to have debris and floating particles removed from his right knee.

The good news is that he didn't need microfracture surgery, which was a possibility. However, it's the third time Quentin has had his right knee operated on, so whether or not he ever will feel totally normal again is up in the air. The Padres expect him to be ready to go for the start of spring training.

Carlos Quentin will undergo his season-ending knee surgery on Tuesday.

It will be the third operation on the slugger's chronically injured right knee. Assuming all goes well and Quentin has a healthy offseason, he should be ready to go for the start of the 2014 season.
