The Rays announced that Cobb, who remained conscious the whole time, was taken to Bayfront Medical Center in St. Petersburg for further examination. Rays spokesman Rick Vaughn later said all tests were normal and that Cobb suffered a mild concussion.
Luke Scott, Matt Joyce and Evan Longoria homered for the Rays, who had lost five of six. Alex Torres (2-0) replaced Cobb and struck out four over 1 2-3 scoreless innings. Fernando Rodney pitched the ninth for his 14th save in 19 opportunities.
Joyce hit a solo homer off Jeremy Guthrie (7-4) in the fifth that put the Rays up 4-2.
RED SOX 5, ORIOLES 4
BALTIMORE (AP) — Mike Carp and Jonny Gomes homered to back an effective pitching performance by John Lackey, and the Boston Red Sox beat the Orioles to end a five-game losing streak in Baltimore.
After dropping the first two games of the series, the Red Sox fell into a 2-0 hole before bouncing back. Carp's home run snapped an 18-inning scoring drought in the fourth, and Gomes made it 5-2 in the sixth with a solo shot that chased Baltimore starter Freddy Garcia (3-4).
Boston leads Baltimore by 2 1/2 games in the AL East.
Lackey (4-5) gave up two runs, seven hits and a walk in seven innings to improve to 12-4 against the Orioles.
Former Oriole Koji Uehara struck out the side in the eighth and Andrew Bailey gave up a two-run homer to Matt Wieters in the ninth before securing his eighth save.
BLUE JAYS 6, RANGERS 1
ARLINGTON, Texas (AP) — Adam Lind and Colby Rasmus both hit two-run homers and the Blue Jays won their fourth game in a row, beat the sliding Rangers.
Even with the unexpected early return of second baseman Ian Kinsler from his rehabilitation assignment, the Rangers' season-long losing streak reached five games. All of those losses are at home, and they've dropped 10 of 14 overall to fall out of first place in the AL West.
Lind put the Blue Jays ahead to stay in the first, when his seventh homer of the season ricocheted high off pole down the right field line. Rasmus hit his 12th homer, and second in two games, in the fourth to make it 4-0.
Those homers accounted for all four runs off Josh Lindblom (0-2), who went six innings on his 26th birthday.
R.A. Dickey (6-8) gave up one run in 5 2-3 innings.
ANGELS 6, YANKEES 2
ANAHEIM, Calif. (AP) — Erick Aybar homered and drove in two runs, and Albert Pujols added two more RBIs in the Angels' victory over the Yankees on Saturday night that sent New York to its fifth straight defeat.
Tommy Hanson (4-2) recorded a season-high eight strikeouts while pitching five-hit ball into the seventh inning for the Angels, who have won three straight after a four-game skid. Josh Hamilton had an RBI double, and Aybar hit an early homer before delivering a tiebreaking RBI single in the sixth.
Brett Gardner had an RBI triple for the Yankees, who matched their worst skid of the season. Mark Teixeira also left in the fourth inning with an aggravated right wrist.
Howie Kendrick had three hits and drew a bases-loaded walk in the seventh for the Angels.
ASTROS 4, WHITE SOX 3
HOUSTON (AP) — Jason Castro and Chris Carter homered in the fourth inning to give Houston the lead and the Astros held on for a win over the White Sox.
The game was tied at 1-1 when Castro launched a solo homer into the bullpen in right-centre to start the fourth inning. Carter's one-out homer clanged off the foul pole in left field to extend the lead to 3-1 and leave starter John Danks (1-3) shaking his head.
Brandon Barnes's double drove in a run in the fifth inning to make it 4-1.
Adam Dunn hit his 18th homer to start the seventh and Gordon Beckham's ground-rule double made it 4-3.
Harrell (5-7) allowed seven hits and three runs with a season-high seven strikeouts in 6 2-3 innings.
Danks yielded five hits and four runs in six-plus innings.
MARINERS 4, ATHLETICS 0
OAKLAND, Calif. (AP) — Henry Blanco hit a sixth-inning grand slam in his Seattle debut to break a scoreless tie, Felix Hernandez pitched seven strong innings to win his third straight decision, and the Mariners beat the Athletics.
The 41-year-old Blanco, a .184 hitter with no home runs coming into the game, was an unlikely candidate to deliver the decisive hit for Seattle. The Mariners signed him Friday, three days after his release by Toronto. He became the oldest Mariners player with a slam.
Hernandez (8-4) struck out five of Oakland's initial eight batters and seven through four innings on the way to eight Ks.
Michael Morse had two doubles among his three hits, including one in the sixth before Blanco's drive stayed just inside the left-field foul pole.
TWINS 6, TIGERS 3
MINNEAPOLIS (AP) — Trevor Plouffe had three hits, including a two-run homer, in his return to the Twins lineup, and Sam Deduno held Detroit in check over seven innings in Minnesota's victory.
Plouffe, back after missing 22 games because of a concussion and left calf strain, was a triple shy of the cycle. He drove in three runs in support of Deduno, who has allowed only five earned runs in his last five starts.
Deduno (3-1) gave up two runs and seven hits to win his third straight decision since being recalled in May. Glen Perkins added his 16th save in 18 chances.
After missing his previous start with shoulder stiffness, Anibal Sanchez struggled with pitch location and only lasted 3 2-3 innings for Detroit. Darin Downs (0-2) gave up three runs and five hits in relief of Sanchez, and took the loss.
NATIONALS 7, INDIANS 6
CLEVELAND (AP) — Anthony Rendon hit his first major league home run following Nick Swisher's ninth-inning error to propel the Nationals to a win over Cleveland.
Two pitches after his foul popup fell between the Indians' first baseman and second baseman Jason Kipnis, Rendon homered into the Nationals' bullpen off Vinnie Pestano (1-2) to stun the Indians and the crowd of 33,307.
Swisher and Kipnis both drifted into foul territory and it appeared either could have made the catch, but neither player appeared to call for it and the ball fell to the ground. Swisher was charged with the error.
Drew Storen (1-1) pitched the eighth for the win while Rafael Soriano worked the ninth for his 18th save. Mike Aviles doubled with two outs, but first baseman Adam LaRoche made a leaping catch of Michael Bourn's line drive to end the game.
