| No. Name | Pos. | B-T | Ht. | Wt. | Age |
| 16 Willy Aybar | IF | S-R | 5-11 | 200 | 25 |
| DH against lefties, also a durable infielder as evidenced by stint subbing for Evan Longoria, scored two of Rays' three runs in Game 7 of ALCS |
| 5 Rocco Baldelli | OF-DH | R-R | 6-4 | 200 | 27 |
| Still can't play every day due to mysterious fatigue symptoms, but two ALCS hits were big ones - three-run homer, RBI single |
| 50 Grant Balfour | RP | R-R | 6-2 | 192 | 30 |
| Struggled in ALCS after brilliant first round and memorable showdown with White Sox's Orlando Cabrera; must rediscover control |
| 8 Jason Bartlett | SS | R-R | 6-0 | 185 | 28 |
| Errors in last two ALCS games uncharacteristic for defensive whiz acquired in offsesason Delmon Young trade |
| 53 Chad Bradford | RP | R-R | 6-5 | 205 | 34 |
| The only Rays acquisition before the trade deadline, submariner has surrendered one run in 22 career playoff games |
| 13 Carl Crawford | LF | L-L | 6-2 | 215 | 27 |
| Led Rays with 10 hits against Boston; still getting feel for his swing after stint on the DL |
| 15 Cliff Floyd | DH | L-R | 6-4 | 230 | 35 |
| Rays' emotional rock back in World Series 11 years after Marlins' improbably first title |
| 22 Matt Garza | SP | R-R | 6-4 | 205 | 24 |
| MVP of ALCS has established his big-game credentials, but probably won't get a start until Game 3 |
| 26 Gabe Gross | OF | L-R | 6-3 | 220 | 28 |
| A woeful 1-for-16 in playoffs but a reliable defender in right field and clutch in late-game plate situations in regular season |
| 41 Michel Hernandez | C | R-R | 6-0 | 215 | 30 |
| On roster because Shawn Riggans isn't ready to return, but doesn't figure to get off the bench barring an injury to Dioner Navarro |
| 39 J.P. Howell | RP | L-L | 6-0 | 175 | 25 |
| Team MVP in the eyes of some, could get more multiple-inning looks against balanced Phils lineup |
| 1 Akinori Iwamura | 2B | R-R | 5-9 | 176 | 29 |
| Leadoff man, who forced the final out that gave Rays the AL pennant, could be more important in non-DH games |
| 36 Edwin Jackson | RP | R-R | 6-3 | 210 | 25 |
| Team leader in regular-season wins, pitched well enough in two ALCS relief appearances to get a look |
| 19 Scott Kazmir | SP | L-L | 6-0 | 190 | 24 |
| Came up huge on road in Game 5, will look to set the tone in World Series at Tropicana Field |
| 3 Evan Longoria | 3B | R-R | 6-2 | 210 | 22 |
| Third pick overall in 2006 draft; eight RBIs in ALCS tied rookie record for any playoff series |
| 57 Trever Miller | RP | R-L | 6-3 | 200 | 35 |
| Limited usage so far; Price's emergence could keep it that way, but extremely tough against lefties |
| 30 Dioner Navarro | C | S-R | 5-9 | 205 | 24 |
| Switch-hitter who has improved all-around game immensely; struggled at plate after hot Division Series, will look to rebound |
| 23 Carlos Pena | 1B | L-L | 6-2 | 215 | 30 |
| Reached base in 40 percent of ALCS plate appearances; vocal leader and one of the faces of franchise |
| 38 Fernando Perez | OF | S-R | 6-1 | 195 | 25 |
| Didn't get a hit but scored two big runs against Red Sox; could be invaluable as pinch-runner and late-game outfield substitution |
| 14 David Price | RP | L-L | 6-6 | 225 | 23 |
| Top pick overall in 2007 draft out of Vanderbilt; breathtaking Game 7 performance should lead to larger role |
| 33 James Shields | SP | R-R | 6-4 | 215 | 26 |
| Two quality starts netted two losses against Boston in Games 1 and 6 thanks mostly to erratic bats |
| 21 Andy Sonnanstine | SP | L-R | 6-3 | 185 | 25 |
| A change of pace from rotation's flamethrowers; came up big in sole ALCS start, just as he had in first round |
| 2 B.J. Upton | CF | R-R | 6-3 | 185 | 24 |
| Building national reputation perhaps moreso than any teammate; four homers, 11 RBIs led Rays' offensive attack vs. Red Sox |
| 35 Dan Wheeler | RP | R-R | 6-3 | 22 | 30 |
| Shaky at times in second round, remains likely choice to close, along with Price, based on situation |
| 18 Ben Zobrist | IF-OF | S-R | 6-3 | 196 | 27 |
| All-around backup who looked more comfortable at the plate as the season went on; should see more action in games in Philly |
