In flurry of moves, A's DFA former Giants reliever in middle of Bay Bridge Series

In flurry of moves, A's DFA former Giants reliever in middle of Bay Bridge Series

In a flurry of roster moves on Saturday, the Oakland A's called up top prospect Franklin Barreto, designated veteran reliever Santiago Casilla for assignment, and optioned starting pitcher Daniel Mengden to Triple-A after activating him from the DL. 

Barreto, 22, has split time between Triple-A Nashville and the big leagues in his second professional season. In 50 games in the minors, Barreto's batted .232 with 10 home runs and 28 RBI.

He's hit .212 with three homers and 10 RBI in 54 big-league plate appearances this season. Baseball America ranked Barreto the No. 43 prospect in baseball entering this season. 

The 37-year-old Casilla, who signed with the A's as a free agent in 2017, lost his job as the closer last season after blowing seven saves in 23 opportunities. In 31 1/3 innings this season, he posted a 3.16 ERA and 1.21 WHIP. 

Mengden, meanwhile, may get an opportunity to pitch with the Sounds over the All-Star Break. He last pitched for the A's on June 23, leaving after two innings with a sprained right foot. 

Oakland also swapped a pair of right-handed relievers, calling up J.B. Wednelken and and optioning Ryan Dull. 

A's notes: Oakland earns MLB-leading 11th win when trailing after seven

A's notes: Oakland earns MLB-leading 11th win when trailing after seven

OAKLAND — If it seems like the A's come back to win a lot of games, it's because they do.

Friday's victory over the Astros marked Oakland's 11th win of the season when trailing after seven innings, the most in all of Major League Baseball. On the flip side, the A's are a perfect 50-0 when leading after seven.

Oakland also leads MLB with a 26-10 record in one-run games; the Astros fell to 16-22 in such games.

--- The A's improved to 11-5 in extra inning games. The 11 extra-inning wins are tied with the Seattle Mariners for the most in the bigs.

--- Friday marked Oakland's first home win against Houston this season. The A's are now 1-6 against the Astros at the Coliseum and 5-9 overall.

--- The A's have won 18 of their last 22 games at home and are 36-24 at the Coliseum for the season.

--- Oakland snapped a 21-run scoreless streak after scoring two runs in the fifth inning.

--- Matt Olson hit the first walk-off home run of his MLB career. It was his second career walk-off hit.

--- Jed Lowrie has recorded multiple hits in four of his last five games, the first time he has done that since April. He is 9 for his last 21, with two home runs and four doubles.

--- Fernando Rodney has yet to allow an earned run in five appearances with Oakland. Overall, he has not allowed an earned run in his last 10 innings.

--- Khris Davis and Jonathan Lucroy are both 0 for their last 13. Lucroy went 0-for-3 with two strikeouts Friday night. Davis was 0-for-4, but did draw a walk.

--- Lucroy threw out his 23rd attempted base stealer of the season to lead Major League Baseball.

Matt Olson keeps A's magic alive with first career walk-off homer

Matt Olson keeps A's magic alive with first career walk-off homer

OAKLAND — Matt Olson doesn't remember a whole lot from his trip around the bases following his first career walk-off home run.

“I blacked out,” he laughed. “I remember chucking my helmet, and just yelling and jumping around with all the guys.”

That type of scene seems to be a nightly occurrence for these Oakland Athletics, now 39-13 in their last 52 games. From record comebacks to late inning histrionics, the A's have become arguably the biggest story in all of baseball.

“We play our best baseball late in games,” said manager Bob Melvin. “Even if we're down, we feel like we have a chance.”

Added Olson: “We've known that we're a very good team all along. We knew going into the year we were going to have a chance to make a run, so we're glad to finally get a little recognition for it. When we go out and win games like this, people will notice a little bit.”

People have certainly noticed, and not just a little bit. The A's have all but erased a 12-game deficit in the last two months, pulling within a single game of the defending World Series champions for first place in the AL West.

Even more incredible than that 39-13 record since mid-June is the way the A's have done it. 21 of those 39 victories have been of the comeback variety, and 15 have seen the winning run scored in the eighth inning or later.

“They're just confident they're always going to come back and have a chance if it's late,” Melvin said. “Success breeds confidence and we've had plenty of both late in games.”

“This team is capable of doing special things like that on a daily basis, and tonight showed that,” added starting pitcher Edwin Jackson. “That was a hell of a game, and I think that's an understatement.”

As Friday's game moved into the later innings, it began to feel like those Oakland heroics might not happen. The A's squandered a golden opportunity to at least tie the game in the eighth inning, failing to score with runners on first and second, and no outs. Olson struck out in a key spot that inning, but ultimately got a chance to redeem himself, and took full advantage.

“Oly's always one swing away from putting you ahead or hitting a home run,” Melvin said. “You saw what he did last year. Maybe he's not on the same pace this year, but he gets big hits for us, and everybody feels good when he's at the plate.”

“Definitely one of the cooler things I've done in my career,” Olson smiled. “It's the most juiced I've gotten on a field, for sure.”
