The Rays' playoff fate will be determined in the next three or four days, beginning with tonight's game against the Yankees at Tropicana Field.
The Rays, nine games out of a playoff spot on Sept. 3, now trail the Red Sox by just a game in the wild-card standings. Each team has three games remaining.
Tonight's 7:10 p.m. game marks the start of a three-game series against the AL East champion Yankees. The Rays' James Shields (15-12) will pitch against Hector Noesi (2-1).
Plenty of tickets remain in all price categories. They can be purchased at the stadium box office, by calling 888-FAN-RAYS or visiting raysbaseball.com.
The game will be televised by Sun Sports and carried on 620-AM radio.
The Red Sox end the regular season with three games against the last-place Orioles, who took three of four against Boston early last week.
MLB Network will show the Red Sox-Orioles game in the Tampa Bay market, starting at 7 p.m.
If the Rays overtake the Red Sox and win the wild card, they will open the best-of-five division series Friday at the Tigers or Rangers. If the Rays and Red Sox tie, they will play a one-game playoff Thursday at the Trop, with the winner traveling to Detroit or Arlington on Friday.
