OAKLAND -- The A’s wrapped up their home schedule on Sunday afternoon with their best record at the Coliseum since 2013, but nobody in their clubhouse actually believes it was the final home game of the year.

An 8-3 loss to the Rangers and missing a chance for a three-game sweep was not how the A’s envisioned closing out their regular season at home. The loss, however, was softened because the Rays also lost earlier in the day, leaving Oakland’s American League Wild Card lead at two games. They are on track to host that pivotal winner-take-all matchup.

The A’s went 33-11 over their last 44 home games to finish 52-29 at home this season, but 52-27 at the Coliseum. They began the season with two games in Japan as the designated home club, losing both to the Mariners. A win on Sunday would have given them their highest win total at home since winning 57 in 2003, but the 52 wins for '19 still puts the A’s in good company with the seventh-best home record in Oakland history, capping their third consecutive season with a winning record at home.

“We’ve played great here for the entire season,” said A’s manager Bob Melvin of the home success, which included 10 walk-off victories. “All the walk-offs and dramatics here, it would have been a little more apropos if we finished it off with a win today, but we didn’t, so that’s a little disappointing.”

While 52 wins in 2013 were enough to capture the AL West crown, the A’s are hoping that same mark will be enough to hang on in the Wild Card race with six road games left.

“This time of year, you take a series win, but we’re more just trying to win every game that we can and not give one away,” Melvin said. “That will be our thinking the rest of the way.”

A’s starting pitchers have found the Coliseum to be a paradise for most of the year, entering the day with a combined 3.51 ERA at home. So it was uncharacteristic when Tanner Roark took the mound and surrendered a home run to Shin-Soo Choo on the first pitch of the game. The right-hander was in danger of a first-inning exit before getting out of it with four runs allowed.

Roark settled down in the second, but he allowed his career-high fourth homer of the game in the third to Willie Calhoun, who also homered in the first frame. The righty was pulled after allowing five runs on six hits and one walk over three innings, digging the A’s a deep hole in his shortest outing of the year.

“Just a rough outing altogether,” Roark said. “They put good swings on bad pitches. I left balls over the middle of the plate a lot, and they got hit hard and far.”

The early struggles came as a surprise to Melvin as Roark had pitched into at least the sixth inning in six of his first eight starts with Oakland, but one start does not undo the stability Roark has been able to bring since arriving from the Reds at the Trade Deadline.

“A lot of times, when you have a chance at a good starter, it’s early in the game, and they got him before he could get into his rhythm,” Melvin said. “They hit some balls out of the ballpark and had him on the run. But this doesn’t minimize our feeling about Tanner. He’s been great for us.”

Semien continues MVP push

Melvin has been making a push for Marcus Semien to garner some attention in the AL MVP Award voting over the last few days, and the shortstop helped himself out Sunday by etching his name alongside some legendary players.

Semien finished the day 2-for-5 with a pair of doubles and an RBI. He scored his 120th run of the season in the fifth, tying Jose Canseco for second-most runs scored in Oakland history and surpassing Rickey Henderson, who scored 119 runs in 1982 and '90. With six games remaining, Semien stands a chance to break the Oakland record of 123, set by Reggie Jackson in '69.

Semien also surpassed Henderson for most homers in a season from the leadoff spot in franchise history on Sept. 16.

“You feel like nobody would ever even touch Rickey’s numbers. I couldn’t have forecasted it,” Melvin said of Semien’s latest accomplishment. “It’s just been an amazing ascend, and [Semien] understands the history of this organization. At some point in time after the season is over, he’s going to realize what he did.”
