LOUISVILLE, Ky. -- Bobby Petrino isnt concerned about his No. 7 Louisville Cardinals being rusty after getting some rest.If anything, the Cardinals coach said the bye-week practices have been as intense as previous workouts that helped them surge from their preseason Top 25 ranking into the national title discussion. Louisville begins the second half of its season Friday night against Duke, looking to bounce back from their disappointing 42-36 loss at Clemson and return to the playoff picture.Louisville (4-1, 2-1 Atlantic Coast Conference) hosts the Blue Devils (3-3, 0-2 ACC) in their first home game since drubbing then-No. 2 Florida State 63-20 nearly a month ago. That signature win vaulted the Cardinals to No. 3 and sparked talk of them running the table in the conference before they fell just short against the Tigers on Oct. 1.Louisville needs a lot of help from other teams to unseat Clemson and possibly win the Atlantic Division, but the goal is winning out to stay in consideration for the four-team playoff. Judging from the Cardinals practice habits, theyre eager to start another run.Weve got a lot of pride on this team, Petrino said. Its always hard when you lose a hard-fought contest, but were working as hard as we can on bouncing back. Theyve shown a lot of resiliency, have come to practice and worked hard. ... That gives us a chance to get to where we know how to play and really excel here in the last part of the season.Though favored by 35 1/2 over the Blue Devils, the Cardinals are wary of Dukes penchant for meeting big challenges this season.Duke upset Notre Dame 38-35 on the road last month and beat improved Army 13-6 last week. While heavy rain from Hurricane Matthew no doubt factored into the Black Knights gaining just 165 yards rushing, the Blue Devils defense did their part in holding Army more than 200 yards below its FBS-best 374-yard average per game to gut out a tough win.However, Duke coach David Cutcliffe acknowledged that stopping Louisville and Heisman Trophy contender Lamar Jackson will be a whole different challenge. Especially with the Cardinals recharged after a week off.I havent seen anybody with the weapons and the completeness this Louisville team has, Cutcliffe said. Theres a reason theyre playing as well as they are. So, that combination has been lethal for them. Weve got our hands full.---Here are other things to watch as No. 7 Louisville returns to action against Duke:LAMAR STILL LEADS: Louisvilles dual-threat sophomore quarterback continues to lead the nation in several offensive categories despite the week off. Jackson is No. 1 with 14 rushing touchdowns, 168 points responsible for and 16 points per game. Hes also second in total offense with 462.6 yards per contest.MILESTONE NEAR: Duke rushing leader Jela Duncan is probable despite leaving against Army with a leg injury after gaining 40 yards on 10 carries. His 354 yards rank 10th in the ACC and hes 54 shy of becoming the programs sixth player to reach 2,000 career yards.BALL HAWK: Louisville cornerback/return man Jaire Alexander has been a force on defense and special teams. He leads the Cardinals with three interceptions after picking off two at Clemson along with forcing a fumble. The sophomore also leads the ACC in punt return average (15.5 yards) and returned one 69 yards for a TD against FSU.SHORT-WEEK PROBLEMS: Duke coach David Cutcliffe says the quick turnaround means the Blue Devils have yet to review film of last weeks Army game. Theyll do that during next weeks bye, and it helps that the following opponent -- Georgia Tech -- also runs a version of the triple option used by the Black Knights.500 CLUB: A Louisville victory would mark the programs 500th in 98 seasons of play against 450 losses and 17 ties.---AP Sports Writer Joedy McCreary in Durham, North Carolina, contributed to this report.---AP College Football: collegefootball.ap.orgCheap Vapormax China .

And while the Chicago Cubs even kept closer Aroldis Chapman in longer than usual on the way to the title, managers dont expect the 2016 postseason to change the way bullpens are managed.The postseason management of the bullpen is extremely different than the regular season management, incoming Colorado Rockies manager Bud Black said Monday. But what does work (is) if you have those types of relievers that have multi-inning performance, who can throw parts of innings and continue, thats very valuable.Miller pitched two innings or more in seven appearances, and Chapman went 2 2/3 in Game 5 of the World Series -- mostly out of necessity. Cleveland manager Terry Francona conceded at the time he wouldnt be able to use Miller like that during the regular season.Terry is right: You cant do that during the regular season, youre going to blow somebody out, Yost said. But in the playoffs, its a lot easier to do. You got to understand, Andrew Miller, these guys dont grow on trees. They are few and far in between, guys that are that durable that can pitch like he did, especially down the stretch.Millers example isnt changing how teams approach the offseason, either. Boston Red Sox general manager Dave Dombrowski said his priority was getting an eighth-inning guy, filling a specific role in front of closer Craig Kimbrel, and did so by acquiring right-hander Tyler Thornburg from the Milwaukee Brewers.Manager John Farrell considers it important to define roles over 162 games.If you look at our usage over our last couple of years the one thing that we have had is that one guy other than the closer where weve used (him) at the highest-leverage point in the seventh or eighth inning, Farrell said. Ideally, yeah, you can give the seventh, eighth and ninth inning to three different relievers and let it run out regardless of where you are in the lineup and what the score is on the winning side. I think our main goal is to identify a guy that its not so much a matchup situation.Franconas theoryy -- an evolving one around baseball -- is that the three biggest outs arent always the final ones.dddddddddddd Theres still value in closing, but if the heart of the order is up in the seventh, eighth or even the sixth inning, that could be the spot for a team to use its best reliever.While playing bullpen bingo became popular in the postseason, Philadelphia manager Pete Mackanin doesnt think its practical during the regular season. It just requires depth and talent, which the Phillies now have more of after signing Joaquin Benoit.The deeper you are in a bullpen the easier it is to go to a real good stopper type pitcher in the sixth or seventh or fifth inning like they were able to do in the World Series, Mackanin said Tuesday. Over the course of a six-month season certainly its harder to do, but the deeper you are in the bullpen the easier it is.Stacking a bullpen with two or three closer types like the Indians gives them a leg up in employing that strategy.I think what teams are trying to do or what successful teams have done have had a seventh- or eighth- or ninth-inning guy, and all three of them can pitch in the ninth inning, Yost said. All three of them can close. When you have that, man, thats a huge advantage late in the game.Even though the new MLB collective bargaining agreement didnt include the addition of a 26th player to rosters, New York Mets general manager Sandy Alderson said theres a trend toward using more bullpen arms. Phillies GM Matt Klentak thinks more off days built into the schedule will help teams if they want to lean more on top relievers, who have more value thanks to the lessons of recent postseasons.As an industry, were appreciating the value that those players can bring, Klentak said, a day after the Giants gave closer Mark Melancon a $62 million, four-year deal, the richest ever for a reliever. During the postseason, as we watched the games and we saw these managers using their elite arms in the higher leverage situation but in earlier innings, we talked a lot internally in the office about whether we thought that was something that might become more mainstream during the regular season. ...I think the fact that some teams had some success with that in October would lead us to think that a lot of managers will probably try that.---AP Baseball Writer Ronald Blum and Sports Writer Howard Fendrich contributed.
