SAN FRANCISCO -- A lot seemed to be going right for left-hander Alex Wood as he breezed through his first five innings against the Tigers on Wednesday afternoon at Oracle Park. He was working at his usual crisp pace, he was missing bats with his slider and he appeared to be on the verge of rebounding from last week’s clunker at Atlanta with his third quality start of the year.

But Wood’s outing ultimately ended on a sour note.

With the game tied at one and a runner on third with two outs in the sixth, manager Gabe Kapler walked to the mound for a brief conference with Wood, who wasn’t ready to give up the ball. Kapler decided to stick with the 31-year-old veteran, but the move ended up backfiring.

The next batter, Eric Haase, crushed a down-and-in slider to left field for a go-ahead two-run shot, lifting the Tigers to a 3-2 win that secured a split of this two-game interleague series at Oracle Park.

“These are the days that are just extremely frustrating,” said Wood, who dropped to his knees after throwing his 93rd and final pitch of the game. “I felt really good. I thought it was the best my slider has been in a long time, if not on the year. To have that happen at the end really sucked, to be honest. It’s really frustrating.”

Wood has proved vulnerable when facing hitters a third time through the order, though Kapler felt comfortable leaving him in to face Haase based on how well he’d thrown for most of the afternoon.

“He looked good up until that point,” Kapler said. “He had just gotten a ground-ball double play. He was feeling pretty strong, efficient and effective. I wanted to make sure that’s where his brain was, and it was.”

Wood, who was coming off his shortest start of the season after giving up six runs over one-plus innings against the Braves last Thursday, made some mechanical adjustments between outings that helped him get his slider back on track, and he was encouraged by his ability to generate nine of his 13 swing-and-misses with the pitch. He walked away with a respectable line, giving up three runs on seven hits over 5 2/3 innings, but his overall results (5.03 ERA) still aren’t up to his standards.

“It’s something to keep building off of moving forward, but it’s time to start getting some good lines to match up with how I’m feeling because it just hasn’t matched up all year,” Wood said. “It’s been extremely frustrating.”

The Giants’ bats couldn’t pick Wood up, recording only seven hits and going 2-for-9 with runners in scoring position to fall to 2-3 through their first five games of this homestand against the last-place Reds and Tigers. The defeat sealed a 13-13 June for the Giants, who suffered eight one-run losses this month.

Evan Longoria launched his third home run in his last five games to put the Giants on the board in the first inning, but they didn’t score again until the seventh, allowing a couple of bases-loaded opportunities to go to waste in the process.

“I think it’s as simple as getting one more big at-bat,” Kapler said. “Sometimes you have a big moment and we have an opportunity to break the game open and we don’t do it. Obviously, with all the confidence that we have in our hitters, we know that it’s in there. We just haven’t been able to string them together.”

One silver lining for the Giants was the return of LaMonte Wade Jr., who returned to the lineup for the first time since May 18 after missing 36 games with a nagging left knee injury. Wade slotted into the leadoff spot and went 1-for-5 with a single, but it wasn’t enough to jolt the offense on Wednesday.

San Francisco will need more consistent production from its offense moving forward, though Wood said he feels the pitching staff outside of Logan Webb and Carlos Rodón can also do more to put the club in a better position to win.

“I think it starts with our staff,” Wood said. “Webby and ’Los have put up their lines, and I think the rest of us need to step our [game] up and start having the lines match up with how we’re feeling. Putting up some zeros and finishing starts with zeros on the board or one run on the board. A lot of those one-run games are on us. We’ve just got to come out and keep grinding and get after it.”
