Both moves have worked out quite well for the Blue Jays.
The victory improved Toronto's record under Gaston to 14-12. One reason for his success has been the hitting of Lind, who is 27-for-78 (.346) with five homers and 22 RBIs in 22 games since his recall from Triple-A Syracuse on June 21.
"I struggled a little when I first came back, then I just turned myself over to the staff and put my future in their hands," Lind said. "I am a believer. When you say you have Cito Gaston as your manager ... even my friends said, 'You have a guy like that, you listen to him. He has got to know what he's talking about.'"
Alex Rios homered for the Blue Jays, who trailed 4-0 after three innings and 7-6 after five.
"It's just a good feeling to win like we did tonight, coming back the way we did," Lind said.
Toronto's comeback took some of the sting away from a poor performance by Shaun Marcum, making his first start in over a month after being sidelined with elbow soreness. Marcum gave up seven runs and eight hits, including three home runs, in 4 2/3 innings.
"He put some pitches up and was not as sharp as he is going to be," Gaston said. "I'm glad we came away with the win for his sake. I'm sure Shaun feels he let the team down."
Jesse Carlson (2-1) pitched 1 1/3 innings of one-hit relief and B.J. Ryan worked the ninth for his 19th save. Ryan gave up a two-out RBI single to Melvin Mora and then issued two walks to load the bases before retiring Ramon Hernandez on a fly ball.
Mora went 4-for-5 with a season-high five RBIs for Baltimore. In six games since the All-Star break, he is 12-for-24 with four home runs and 14 RBIs.
"In scoring position, I like the RBIs. I've been doing that all year long," said Mora, who took over the team lead in RBIs with 62.
Nick Markakis and Hernandez homered for the Orioles, who have lost 10 of 14.
The Blue Jays took the lead for good with a three-run sixth. After Fernando Cabrera (0-1) retired the first two batters, he gave up a single and a walk. Alberto Castillo entered, and Lind hit the left-hander's second pitch over the scoreboard in right.
"That was the pitch I wanted," Castillo said. "I just hung a slider and he is a good hitter and took a good swing. Just one bad pitch."
Rod Barajas added an RBI single in the eighth.
Orioles starter Garrett Olson allowed six runs and a season-high nine hits in 4 2/3 innings. The rookie has given up 18 runs in his last three starts.
"If he trusts his stuff and attacks the hitters maybe a little more aggressively, he'd probably find the outcome to be a little bit more positive for him," Orioles manager Dave Trembley said. "But that's something he's going to have to figure out on his own."
After Olson yielded five runs in the fifth, Mora hit a two-run homer and Hernandez added a solo shot in the bottom half to put the Orioles up 7-6. It would be Baltimore's final lead.
Markakis hit a two-run homer in the first, and a two-run double by Mora made it 4-0 in the third.
"When you're facing a guy like Marcum and you get the runs off him early, you think you're going to be in a situation where you're going to have a good chance to win the game," Trembley said. "But you take nothing for granted. We let them back in the game and we just couldn't stop them."
The Blue Jays got a fourth-inning run on a sacrifice fly by McDonald, but left the bases loaded for the second time.
That shortcoming was corrected in the fifth. After Rios led off with a homer, the Blue Jays loaded the bases with two outs for McDonald, who doubled off the left-field wall to chase Olson and put Toronto ahead 5-4.
McDonald came in with a .190 batting average and two RBIs in 36 games.
"Every time I get a chance to play, I try to do something to get myself back in the lineup," he said. "You always want to contribute, and I haven't been able to do that as much as I would have liked to."
Markakis went 1-for-2 with a homer and a walk against Marcum, improving his lifetime numbers against the right-hander to 8-for-17 with four walks, five homers and six RBIs. ... Eight of Lind's last 15 hits have gone for extra bases. ... Despite his poor outing, Olson lowered his career ERA against Toronto from 17.05 to 14.73.
