Closer Report: Dedicated Dodger

The good news, if you're a Kenley Jansen owner, is that the Dodgers' closer should be able to return by mid-September. He's been sidelined since August 27, due to an irregular heartbeat.

The scarier news, if you're Jansen himself, is that you'll need to undergo a surgical procedure in the off-season in order to correct the arrhythmia. Details here from the Los Angeles Times:
The heart procedure Jansen is considering is called cardiac ablation, which typically inserts a small catheter through a vein and through to the heart, where an electrical charge is used to destroy the problem areas of the heart.
"If I do the surgery I will be off the [blood thinning] medicine, so that would be good for me," Jansen said.
So it's no big deal, really. They'll just correct the problem by threading a tube into his heart, then frying whatever isn't working. Problem solved.
Tip of the cap to Jansen for his commitment to return this season, and we wish the big man an easy recovery, free of complications. He's been a monster for fantasy purposes (13.7 K/9, 0.88 WHIP), delivering an easy profit for early investors. While we wait for him to reclaim the ninth, Brandon League and Ronald Belisario will handle the end-game for LA.
As soon as Kenley is back, he'll return to his favored position in the index below …

Vinnie Pestano picked up a pair of rogue saves over the holiday weekend, while Chris Perez was attending the birth of Dale Thayer's kid. Or something. (I might be mixing up my player blurbs. They all kinda blend together at this point in the season). Pestano then returned to the eighth on Tuesday, pitching a clean frame while facing the top of Detroit's order, striking out two. In the process, he lowered his ERA to 1.96 and his WHIP to 1.02. He's been a holds-league warrior.
Throwing hasn't been the issue for Huston Street — he reportedly tossed a bullpen session on Tuesday — but, as Padres manager Bud Black reminds us, "He has to get comfortable fielding his position, covering first, fielding the bunt." Street is still dealing with a tweaked left calf, an injury suffered while covering first to close out a save against the Pirates. Luke Gregerson has the ninth in Street's absence.
Red Sox manager Bobby Valentine — who we should probably just call the interim manager at this point — told reporters that Alfredo Aceves will be stretched out in the final weeks. (He probably didn't mean the right-hander would be tortured, Inquisition-style, but maybe we can't rule that out, given their history). Aceves might see a start before the end of the season. Andrew Bailey now has the closer's role for Boston; he converted a save opportunity on Tuesday night vs. the Mariners.
