ST. PETERSBURG, Fla. (620 WDAE) -- Alex Cobb fell flat in his chance to give the Tampa Bay Rays a second straight win, as he allowed seven run and could not get through the fifth inning as the Seattle Mariners defeated Tampa Bay 7-4 Saturday.

Cobb allowed the first batter to reach in four of the five innings he worked, with the Mariners taking the lead in the second inning, the only frame Cobb retired the first batter of the inning.  Cole Gillespie's first home run gave Seattle a 1-0 lead.

Tampa Bay countered in the bottom of the second, as James Loney homered to tie the game at 1-1.  Yunel Escobar then drew a walk, and Logan Forsythe's single moved the 

Rays shortstop to third base.  Ali Solis then picked up his first major league RBI as his sacrifice bunt brought in Escobar to make it a 2-1 game.  The Mariners took the lead for good in the fourth, as Dustion Ackley singled to start the inning.  After a flyout by Gillespie, a grounder by Brad Miller went off Cobb's glove and in to right field for a base hit, moving Ackley to third base.  Willie Bloomquist then singled in Ackley to tie the game, and Endy Chavez lifted a fly ball to center, scoring Miller to break the tie.

Cobb's afternoon would come to an end an inning later, as Robinson Cano singled to lead off, moved to second on a walk to Kyle Seager, and took third on a single by Mike Zunino.  Ackley then cleared the bases with a double off the wall in center field.

Cesar Ramos would allow Ackley to score three batters later on a double by Bloomquist.

Tampa Bay got back to withing three runs in the eighth, as Desmond Jennings doubled with one out, and scored on a two-run blast by Evan Longoria, hit seventh of the year.

Tampa Bay will look to rebound Sunday, when Chris Archer (3-2, 4.00 ERA) takes on Felix Hernandez (8-1, 2.57 ERA).  Coverage on WDAE starts Sunday morning at 11:30 with the Suncoast Hyundai Dealers Inside Pitch.  First pitch is scheduled for 1:40.

NOTES: Kirby Yates, called up Saturday when Josh Lueke was designated for assignment, make his major league debut in the sixth inning, pitching 1 2/3 scoreless innings.
