ARLINGTON -- Khris Davis looked downright giddy as he circled the bases a second time at Globe Life Park on Sunday afternoon. The newly minted member of the 40-homer club had every reason to be.
The A's slugger also had reason to want more.
"It's pretty cool," Davis said. "I'm proud of myself. At the same time, we still have a couple more weeks, so I don't know why 45 isn't out of the question."
"We have 13 games left," A's manager Bob Melvin said, "so I know he's not looking for a day off tomorrow."
Not since 2000 had the A's employed a 40-homer player before Davis totaled two in the A's series-clinching 5-2 victory over the Rangers to reach the mark. His previous career high was 27, set with the Brewers last year.
Davis, 28, is obliterating another prior career high, too, heading back to the Bay with 99 RBIs in tow -- 30 more than he's tallied in any of his other three seasons, even while playing his home games in the ultimate pitcher-friendly confines of the Coliseum.
"He's really comfortable here," Melvin said. "He likes it here, gets along great with the guys. A lot of power hitters don't really want to come to Oakland, based on the fact it's a little tougher to hit the ball out of the park, but I don't think that crosses his mind."
The left fielder is one of only four players in the Majors with at least 40 homers this season and, with 13 games to play, could easily surpass Jason Giambi's total of 43 with the A's in 2000 -- even after waiting until his 14th game of the season to notch his first one.

Sunday's blasts, giving him 10 against Texas this season, more than any other opponents in Rangers history, perfectly showcased Davis' incredible power, with one being sent to left, and the other to right for an opposite-field shot.
"It's impressive," Melvin said. "I told him 45 was more impressive than 40, though."
Just eight times have the A's seen a 40-homer season from one of their own since the club moved to Oakland in 1968.
"That fuels me," Davis said. "It's easy getting here, but staying here is the hardest part. It's cliché, but true."
