Pence's two-out RBI single in the ninth inning lifted the Houston Astros to a 4-3 win over the Los Angeles Dodgers. But Pence called an 11-pitch walk by Sanchez earlier in the inning the key to the game.
"Outstanding at-bat," Pence said. "That does a lot more than the box score will ever show. Whenever you work an at-bat like that with that many pitches with two strikes down in the count you have to think of it like running 11 sprints for the pitcher. Then you get on base it's kind of deflating."
The Astros trailed 3-1 entering the ninth inning before Bourn tied it with his two-out, full-count double down the right-field line that scored two against Kenley Jansen (1-1), the hard-throwing rookie who is the latest pitcher the Dodgers have given a shot to close games.
Bill Hall started the rally with a one-out single and Sanchez walked with two outs. They advanced on a double steal to put the tying runs in scoring position for Bourn.
"I told [Sanchez] as soon as he got to first base to watch me," Hall said. "I was thinking about taking off because I knew he was throwing some pitches without even taking a look at me and I knew if we could get to second and third we were going to have a good chance for Mike to get that hit and score two runs."
By the time Pence came to the plate, Jansen had already thrown 36 pitches in the inning.
"He was just making me exhausted out there," Jansen said of Sanchez. "I was trying to catch my breath. It was a tough at-bat."
Dodgers manager Don Mattingly said he still has confidence in Jansen despite Monday's struggles.
"He threw the ball good tonight," he said. "It was that kid, Sanchez, that had a good at-bat against him. He kept on throwing strikes, but he kept fouling balls off. He walks him and gets Bourn up there. The biggest thing today is that he didn't get ahead in the count."
Hall, who was 0-for-11 entering the game, went 4-for-4 with a pair of doubles.
Houston manager Brad Mills was glad to have Pence at the plate with the game on the line.
"He's the guy we want up there, no doubt," Mills said. "He's going to give a big at-bat every time."
Jeff Fulchino (1-2) pitched 1 2/3 scoreless innings for Houston.
Andre Ethier broke a 1-all tie with a two-out pinch hit single in the seventh inning. His hit to shallow center field scored Navarro and gave Los Angeles a 2-1 lead. Bourn thought he'd grabbed the grounder, but instead ran past it for an error that allowed Russell Mitchell to score and Ethier to take second base.
Ethier did not start on Monday after leaving Sunday's game with various injuries after crashing into a fence chasing a fly ball. Navarro hit a ground-rule double to the corner of right field before Houston intentionally walked Mitchell with starting pitcher Clayton Kershaw on deck.
After Mitchell took second, Ethier came out to pinch hit and sent Kershaw to the dugout.
