Description: Athletics closer Sean Doolittle allowed a run in the ninth to blow a save in the American League Wild Card game against the Royals on Tuesday.
Insight: Doolittle did all he could but was not able to prevent the Royals from scratching out a run to tie. Pinch-hitter Josh Willingham hit a bloop single to start the inning. Pinch runner Jarrod Dyson took second on a sacrifice bunt, stole third and then scored on a sacrifice fly. Doolittle stayed in the game to pitch a scoreless 10th.
Description: Mariners general manager Jack Zduriencik said Tuesday that pitching prospect Danny Hultzen "should be" 100 percent for spring training according to MLB.com.
Insight: Hultzen is making his way back from rotator cuff surgery and threw his third and final instructional league outing Tuesday. He will be shut down until spring training. Hultzen was the No. 2 overall pick in 2011.
Description: The Red Sox have not decided whether they'll tender a qualifying offer to free agent closer Koji Uehara according to Brian MacPherson.
Insight: The problem is the one-year qualifying offer on this year's market is expected to be around $15.1 million. That is quite a hefty price for a 40-year-old closer that blew three saves after Aug. 21. We expect the Red Sox to try and bring Uehara back but will try and negotiate with him on the open market.
Description: Tigers closer Joe Nathan threw a perfect ninth inning to preserve a 3-0 lead and capture his 35th save of the season on Sunday.
Insight: The Tigers scored two runs in the bottom of the eighth to give Nathan a three-run cushion. Nathan ends the season with a 4.81 ERA, the 10th highest mark in the history of the league to have recorded 30 saves or more. Since July, his ERA has been under 3.50, but overall, there still isn't much confidence he will get the job done in the playoffs.
Description: Rangers reliever Neftali Feliz saved his 13th game of the season on Saturday as Texas defeated Oakland, 5-4.
Insight: Feliz did allow two base runners, but catcher Robinson Chirinos threw the first one out who was trying to steal second and Feliz stranded the second one at first base. Feliz has saved 13 out of 14 of his opportunities and has a 1.99 ERA in 31 2/3 innings this year.
Description: Mariners closer Fernando Rodney finishes day for Seattle's bullpen.
Insight: Nine relievers combined for the win against the Blue Jays, with Danny Farquhar getting the victory. Rodney did allow one run, but struck out two. He now has 47 saves on the year, with a 2.80 ERA. Elite stats from the closer position.
Description: Nationals pitcher Blake Treinen allowed four runs and eight hits in four 1/3 innings Thursday in the first game of a doubleheader against the Mets.
Insight: Treinen is simply a spot starter for Washington, who has already clinched the division and needed 18 innings from the staff on Thursday. He is likely done pitching this year and finishes at 2-3 with a 2.49 ERA in 50 2/3 innings.
Description: Reds closer Aroldis Chapman struck out the side for his 34th save.
Insight: He had to retire Ryan Braun with runners on the corners, to end the game. He did so by blowing Braun away with an 102 MPH fastball. Chapman has a 2.12 ERA, and has secured another monster season.
Description: Angels manager Mike Scioscia told the Los Angeles Times that he "will consider" Cory Rasmus for a playoff start.
Insight: This would have been way out of the question just a few weeks ago, but based on the Angels rotation beyond Jered Weaver, it is not out of the question. He has not gone more than four innings or thrown more than 59 pitches in any outing, so any playoff start he might receive will likely be pretty brief.
Description: Blue Jays pitcher Daniel Norris will make a spot start on Thursday versus the Mariners according to MLB.com.
Insight: It was supposed to be Marcus Stroman's start, but he is suspended and when he returns, Stroman will pitch out of the bullpen. Norris has allowed two earned runs, four hits and three walks in three 1/3 innings out of the bullpen in September.
Description: Royals closer Greg Holland locks down 43rd save of season.
Insight: The entire bullpen came up huge for Kansas City, as they went 3 2/3 scoreless innings of one-hit ball. Holland sealed the deal with a perfect ninth and two strikeouts along the way. He is an elite option at the closer position.
Description: Nationals closer Rafael Soriano allowed a run but converted the save against the Marlins on Sunday.
Insight: With closer Drew Storen unavailable, Soriano received the chance to pitch the ninth. Soriano gave up a leadoff double, which came around to score on a sacrifice fly, but Soriano preserved the one-run victory.
Description: Brewers closer Francisco Rodriguez's resurgence continued Saturday night.
Insight: He has been amazing all season, and that continued against the Pirates, as Rodriguez locked down his 43rd save. The 3.09 ERA is nothing to cry home about, as a closer, but in no way is it terrible.
Description: Pirates closer Mark Melancon has not been great in non save situations this season, since becoming closer.
Insight: He took the loss to the Brewers, giving a run in the ninth, dropping his record to 3-5. However, Melancon has been extremely reliable when Pittsburgh has the lead, with 31 saves a 1.96 ERA. He is an extremely dependable fantasy closer.
Description: Phillies reliever Ken Giles earned his first career save against Oakland on Saturday.
Insight: With Jonathan Papelbon serving a seven-game suspension, Giles was in line for the save. He went three up and three down, with one strikeout. The flame-thrower is the future at the closer position for Philadelphia.
Description: Tigers closer Joe Nathan walked another tight line, but was able to shut the door for his 33rd save against the Royals, on Saturday afternoon.
Insight: Kansas City was able to get guys guys on 2nd and 3rd with two outs, but Nathan got Raul Ibanez to ground out to first to end the game. While he has a nice number of saves, Nathan's 5.01 ERA continues to be extremely alarming.
Description: Angels closer Huston Street shut the door for his 39th save of 2014.
Insight: He has been fantastic all season. Street now has 15 saves pitching for the Angels, and a 1.26 ERA combined between with his time in San Diego and Los Angeles. He is an underrated fantasy closer, who pitches at an elite level.
Description: Brewers closer Francisco Rodriguez recorded his 42nd save of the year, shutting down the Cardinals in the bottom of the 12th to hold onto a 3-2 victory.
Insight: K-Rod nearly tossed up a game-tying home run to Johnny Peralta, but the fly ball died at the warning track and was caught. Rodriguez has had his struggles this year, but he is third in the National League in saves and has converted 42 out of 47 opportuntities.
