| PR | Name | Team | Games | Win | L | Save | IP | K | H | BB | ER | ERA | FV/ip |
| 1 | Eric Gagne | LOS | 77 | 2 | 3 | 55 | 82.1 | 137 | 37 | 20 | 11 | 1.2 | 7.86 |
| Over 52 saves 2 seasons in a row. 137 strikeouts last season in 82 innings. |
| 2 | Keith Foulke | BOS | 72 | 9 | 1 | 43 | 86.2 | 88 | 57 | 20 | 20 | 2.08 | 6.86 |
| Coming off the best year of his career, Foulke switches coasts and heads to Boston. |
| 3 | M. Rivera | NYY | 64 | 5 | 2 | 40 | 70.2 | 63 | 61 | 10 | 13 | 1.66 | 6.9 |
| Until proven otherwise, Rivera is still among the best in the game. |
| 4 | E. Guardado | SEA | 66 | 3 | 5 | 41 | 65.1 | 60 | 50 | 14 | 21 | 2.89 | 6.56 |
| Still not an absolute lock to be the closer in Seattle, but hard to argue he won't be the man. |
| 5 | Troy Percival | ANA | 52 | 0 | 5 | 33 | 49.1 | 48 | 33 | 23 | 19 | 3.47 | 6.18 |
| May be starting to age. |
| 6 | Billy Wagner | PHI | 78 | 1 | 4 | 44 | 86 | 105 | 52 | 23 | 17 | 1.78 | 6.3 |
| Drops a couple notches due to injury concerns. |
| 7 | Isringhausen | STL | 40 | 0 | 1 | 22 | 42 | 41 | 31 | 18 | 11 | 2.36 | 5.81 |
| Only made 40 appearances, but did have lowest ERA of his career. |
| 8 | J. Borowski | CHN | 68 | 2 | 2 | 33 | 68.1 | 66 | 53 | 19 | 20 | 2.63 | 5.8 |
| The pressure is off in Chicago. The bullpen is stacked. |
| 9 | A. Benitez | FLA | 69 | 4 | 4 | 21 | 73 | 75 | 59 | 41 | 24 | 2.96 | 5.03 |
| The Marlins still have an excellent pitching staff, so Benitez should get plenty of save opps. |
| 10 | John Smoltz | ATL | 62 | 0 | 2 | 45 | 64.1 | 73 | 48 | 8 | 8 | 1.12 | 7.27 |
| Keep an eye on Smoltz in spring training as he recovers from surgery. |
| 11 | Matt Mantei | ARI | 50 | 5 | 4 | 29 | 55 | 68 | 37 | 18 | 16 | 2.62 | 6.91 |
| Sold pick. Strikes out a lot of batters. |
| 12 | Rob Nen | SF | 0 | 0 | 0 | 0 | 0 | 0 | 0 | 0 | 0 | 0 | 0 |
| Unclear how good Nen will be this season after missing 2003. But its clear its his job in SF. |
| 13 | Octavio Dotel | HOU | 76 | 6 | 4 | 4 | 87 | 97 | 53 | 31 | 24 | 2.48 | 4.21 |
| With Wagner gone all eyes are currently on Dotel. Pressure season. |
| 14 | Billy Koch | CHA | 55 | 5 | 5 | 11 | 53 | 42 | 59 | 28 | 34 | 5.77 | 3.85 |
| Horrible season last year. Mgmt and fans hoping for a rebound. |
| 15 | Jorge Julio | BAL | 64 | 0 | 7 | 36 | 61.2 | 52 | 60 | 34 | 30 | 4.38 | 5.32 |
| Will have DeJean potentially stealing a save here and there this season. |
| 16 | B. Looper | NYM | 74 | 6 | 4 | 28 | 80.2 | 56 | 82 | 29 | 33 | 3.68 | 4.96 |
| Whats good enough for the Marlins is better for the Mets. |
| 17 | M. MacDougal | KAN | 68 | 3 | 5 | 27 | 64 | 57 | 64 | 32 | 29 | 4.08 | 5.11 |
| First season as closer was generally a big success for MacDougal. |
| 18 | T. Hoffman | SDG | 9 | 0 | 0 | 0 | 9 | 11 | 7 | 3 | 2 | 2 | 3.56 |
| In case Hoffman doesn't regain his form, the Padres also have Beck. |
| 19 | B. Wickman | CLE | 0 | 0 | 0 | 0 | 0 | 0 | 0 | 0 | 0 | 0 | 0 |
| Wickman's job to lose. However, out of all RP comebacks (Nen, Hoffman), this is toughest. |
| 20 | D. Graves | CIN | 30 | 4 | 15 | 2 | 169 | 60 | 204 | 41 | 100 | 5.33 | 1.93 |
| Back to the bullpen. Graves doesn't strike out many batters, but he's proven effective as a closer. |
| 21 | Danny Kolb | MIL | 37 | 1 | 2 | 21 | 41.1 | 39 | 34 | 19 | 9 | 1.96 | 6.09 |
| Kolb is one to watch. Too bad he doesn't play for a better team. |
| 22 | F. Cordero | TEX | 73 | 5 | 8 | 15 | 82.2 | 90 | 70 | 38 | 27 | 2.94 | 4.63 |
| Too inconsistent to rank much higher at this point, but he does have power. |
| 23 | Justin Speier | TOR | 72 | 3 | 1 | 9 | 73.1 | 66 | 73 | 23 | 33 | 4.05 | 3.57 |
| The closing role is open in Toronto, Speier could be the guy. |
| 24 | Rocky Biddle | MON | 73 | 5 | 8 | 34 | 71.2 | 54 | 71 | 40 | 37 | 4.65 | 5.29 |
| The main closer for the Expos, but there will be fewer games to close this season. |
| 25 | Lance Carter | TAM | 62 | 7 | 5 | 26 | 79 | 47 | 72 | 19 | 38 | 4.33 | 4.68 |
| The Devil Rays have a pretty solid bullpen-- 3 guys. Carter is tops, but will be pressed. |
| 26 | A. Rhodes | OAK | 67 | 3 | 3 | 3 | 54 | 48 | 53 | 18 | 25 | 4.17 | 3.33 |
| Likely to be the A's closer. |
| 27 | F. Rodney | DET | 27 | 1 | 3 | 3 | 29.2 | 33 | 35 | 17 | 20 | 6.07 | 2.93 |
| The Tigers really like Rodney. But don't forget that he is a Tiger. |
| 28 | Sal. Torres | PIT | 41 | 7 | 5 | 2 | 121 | 84 | 128 | 42 | 64 | 4.76 | 2.77 |
| The Pirates bullpen is wide open. Torres may move back out of rotation and into closing role. |
| 29 | S. Chacon | COL | 23 | 11 | 8 | 0 | 137 | 93 | 124 | 58 | 70 | 4.6 | 2.95 |
| Closing role is open in Colorado, Chacon may move out of rotation into the role. |
| 30 | Open | MIN | 0 | 0 | 0 | 0 | 0 | 0 | 0 | 0 | 0 | 0 | 0 |
| Departure of Guardado leaves a hole for the Twins. |
| 1 | Ugueth Urbina | Free | 72 | 3 | 4 | 32 | 77 | 78 | 56 | 31 | 24 | 2.81 | 5.55 |
| The best free agent reliever available. |
| 2 | Tim Worrell | PHI | 76 | 4 | 4 | 38 | 78.1 | 65 | 74 | 28 | 25 | 2.87 | 5.82 |
| Will get a few saves in Philly, but Worrell will be number 2 behind Wagner. |
| 3 | Mike DeJean | BAL | 76 | 5 | 8 | 19 | 82.2 | 71 | 86 | 39 | 43 | 4.68 | 4.06 |
| Could get a few saves filling in for Julio. |
| 4 | Rod Beck | SDG | 36 | 3 | 2 | 20 | 35.1 | 32 | 25 | 11 | 7 | 1.78 | 7.02 |
| May have to be the Padres closer if Hoffman's return proves ineffective. |
| 5 | Jose Mesa | PHI | 61 | 5 | 7 | 24 | 58 | 45 | 71 | 31 | 42 | 6.52 | 4.53 |
| No team seems to be interested in Mesa. |
| 6 | M. Williams | TAM | 68 | 1 | 7 | 28 | 63 | 39 | 66 | 41 | 43 | 6.14 | 3.95 |
| Part of 3 fairly decent closers in Tampa Bay who will all share some of the role. |
| 7 | J. Jimenez | CLE | 63 | 2 | 10 | 20 | 101.2 | 45 | 137 | 32 | 59 | 5.22 | 2.88 |
| Wickman is not a lock for a healthy return. But a possibility in Cleveland is not worth much. |
| 8 | Danys Baez | TAM | 73 | 2 | 9 | 25 | 75.2 | 66 | 65 | 23 | 32 | 3.81 | 4.53 |
| Part of 3 fairly decent closers in Tampa Bay who will all share some of the role. |
| 9 | S. Williamson | BOS | 66 | 5 | 4 | 21 | 62.2 | 74 | 54 | 34 | 29 | 4.16 | 5.28 |
| Foulke in. |
| 10 | B. Fuentes | COL | 75 | 3 | 3 | 4 | 75.1 | 82 | 64 | 34 | 23 | 2.75 | 3.84 |
| If not Chacon, maybe Fuentes. Does have power. |
