Jed Lowrie led the way in Motown, enjoying a four-hit night that helped the A's bypass the Angels and claim sole possession of third place in the American League West.
Lowrie homered for the second time in as many days and also notched the go-ahead single in the ninth following a pinch-hit double from Matt Joyce. The veteran infielder, who later scored on a Dustin Fowler single, reached base in all five plate appearances.
"Pretty good night," A's manager Bob Melvin said, grinning. "We've seen Jed have some pretty good nights. He went through one little stretch there where he had a little bit of a slump going, but he's been as consistent as anybody in the American League this year."
The A's, who overcame a three-run deficit in the final innings of Tuesday's opener, have scored the winning run in the eighth inning or later in seven of their 13 wins this month. Lowrie has been front and center in many of them; Tuesday's ninth-inning knock gave him 15 go-ahead RBIs on the season.
Lowrie, routinely orchestrating a hitting clinic, fouled off the first two pitches he saw from right-hander Shane Greene, falling in an 0-2 hole before working his way back to 2-2, ultimately driving a fastball up the middle.
"That's something that you learn with experience, and having the determination to stay within that approach I think makes the situations easier to handle," Lowrie said. "It doesn't mean that you're always going to have success, it just means you know what you're trying to do."
The A's scripted their latest heroics in support of starter Frankie Montas, who was roughed up for six runs and eight hits in just three innings, after allowing two runs or fewer in four of his first five outings.
Oakland came to life in the fourth against Tigers starter Blaine Hardy, taking advantage of a two-out error with consecutive doubles from Mark Canha and Jonathan Lucroy that brought in three runs to cut Detroit's lead in half. After the Tigers responded with a run in the home half of the inning, the A's returned for the fifth with more ammunition, striking for back-to-back home runs.
A two-run homer from Chad Pinder was followed by a solo shot off the bat of Lowrie. Their efforts helped extend the A's ongoing modern Major League record for consecutive games with a home run to 27.
"As soon as [Lucroy] hits the ball down the third-base line and it's 6-3, our guys felt good again," Melvin said. "Whenever you're down big early like that, you know you're gonna have to fight back and score a couple of runs to give yourself some momentum. There were a lot of big hits in the game."
Likely All-Star Blake Treinen secured his 19th save with a scoreless ninth, following key contributions from Chris Hatcher and Emilio Pagan -- each chipping in two innings -- and Ryan Buchter, who left the bases loaded in the eighth.
"We've been putting together such good at-bats on a consistent basis that it didn't feel like we were out of it," Lowrie said. "This team has so much power, we can make a big comeback in a matter of a couple innings, and you saw that tonight."
MOMENTS THAT MATTERED Buchter, activated from the DL on Monday after being sidelined for two months, found himself in quite the pickle in the eighth inning. After offering up a one-out double to Jeimer Candelario, Buchter was ordered to intentionally walk Nicholas Castellanos ahead of Victor Martinez. Buchter managed to strike out Martinez, before walking Niko Goodrum to load the bases in a tied game. The lefty immediately fell behind, 2-0, before firing three straight strikes to squash the threat.
"Talk about a tough walk," Melvin said. "Castellanos has been their best guy, but Victor Martinez has caused a lot of pain over the years here. To walk Castellanos knowing Victor was coming up was a tough thing to do, but matchup-wise at the time, not only do you have a chance to get a double-play ball but you keep their hottest hitter from potentially driving in the go-ahead run."
SOUND SMART The A's have won seven consecutive meetings with the Tigers and 13 of the past 18 since June 2, 2015 -- including nine of 12 at Comerica Park.
HE SAID IT "He's an excellent hitter, almost top tier. He's a guy that you can't fall into patterns, you have to be careful with what you throw him. I mean, he's not a guy that's going to generally make you pay by hitting a home run, but having him on base isn't fun either. He's a tough hitter to face, and you try to limit the damage." -- Hardy, on Lowrie
UP NEXT Right-hander Chris Bassitt will be recalled from Triple-A Nashville on Wednesday for a start against the Tigers, who will counter with righty Mike Fiers (5-4, 4.29 ERA) in the 4:10 p.m. PT matchup at Comerica Park. Bassitt last pitched for the A's on Friday, surrendering five runs (four earned) on six hits in 5 1/3 innings against the White Sox.
