SAN FRANCISCO -- Rangers manager Bruce Bochy has always been known for his management of the pitching staff long before he got to Texas. 

And while his management during Saturday night’s game against the Giants wasn’t exactly planned, it worked out all the same. 

Bochy said Texas starter Andrew Heaney had a little bit of a cold earlier this week in Oakland and was unable to complete his bullpen. Bochy and pitching coach Mike Maddux knew Heaney's stamina coming off that bug might not have carried him deep into the game.

Instead, the Rangers bullpen and offense carried them to a 9-3 victory over the Giants at Oracle Park to secure a series win and a winning Bay Area road trip. 

Bochy quickly recognized that Heaney didn’t have it and gave him the quick hook after just 1 1/3 innings. The lefty faced nine batters, gave up three hits and walked two, ultimately ending his scoreless streak at a career high 15 2/3 innings by allowing one run in the first inning.

He then turned it over to right-hander Grant Anderson and the bullpen for the rest of the night. 

“When Mike and I talked about it, [Heaney] couldn't take a 'pen and he was pretty washed out,” Bochy said. “So we were a little concerned about him in tonight's game, and watching him, we just knew he wasn't quite himself. He was battling out there. He did get a big strikeout, but where they were in the order, we had Anderson ready. We went ahead and made that move.”

Anderson entered the game for Heaney with the bases loaded and one out in the second inning and quickly induced a 3-6-1 double play to escape the jam. The rookie tossed 2 2/3 innings and allowed just one run -- a home run from Michael Conforto -- to keep the Giants at bay.

Anderson said he and all the right-handed arms in the bullpen knew that if Heaney got pulled early, they would be the first ones up. He got the call, and took full advantage of it.

Bochy noted that while it was just the second inning, it was a tie game at the time, so the double-play ball from Anderson may have actually saved Texas from letting the game spiral out of control.

“This kid, he's got no fear,” Bochy said of Anderson stepping up. “He wants to be out there. He's got a great way about him. He showed that the first time I brought him in in Detroit [in his MLB debut]. He has shown that you know, during the times he's been here. He's just got a little different look with the sidearm, and with how they were stacked up, it was a good matchup for him tonight.”

Anderson and a trio of relievers behind him in Chris Stratton, Josh Sborz and Brock Burke combined for 7 2/3 innings, while allowing just two runs among them. For a group that has struggled through much of the season, it was a quality night for an unplanned bullpen day.

“I just didn't pitch well, you know what I mean?” Heaney said. “I knew I had a short leash and I put us in a situation there early where Boch had to go to the bullpen. I’m not happy about how it started, but obviously, Grant, Strat, Sborz and Burke did a great job coming in and getting the job done and finishing up the game. Again, I'm not happy about how I started the game, but obviously really happy that those guys picked me up and the hitters did what they did and we got the win.”

While the bullpen stole the show, the Rangers offense exploded for nine runs on 16 hits against Giants pitching. Texas had multi-hit nights from six batters, including utilityman Ezequiel Duran, who was a home run shy of the cycle.

It all propelled Texas to its 70th win of the season, making it the fastest of any season in franchise history to reach that mark.

“It was a team win all around,” Anderson said. “ I came in for Andrew and picked him up. Strat came in for me and picked me up, and the offense kind of did that all night, which is what they've done all year. That's what makes a good team a good team, when everybody plays their part and everybody grinds through the game and gets the win.”
