He did, and it turned out to be the right choice.
Gonzalez, playing right in Boston's injury-riddled outfield, drove in the tiebreaking run to help lift the Red Sox to their 14th win in 19 games, a 6-4 victory over the Detroit Tigers on Wednesday night.
"Keep him in, let him stay in, have (Kevin) Youkilis go to third (from first), I don't know," Valentine said, smiling when asked what his plan usually is to get the slow-footed Gonzalez out of the outfield.
Valentine said at one point he was talking with bench coach Tom Bogar about lifting Gonzalez in the sixth, but then said, "No, he's going to come up again."
Boston currently has six outfielders on the disabled list.
Gonzalez had a pair of doubles for Boston, his second coming after he had a ball bounce out of his glove for the tying hit.
"We joke around and say, 'Who's going to play the Little League game and get the six-inning pull?' " said Gonzalez, mostly a first baseman.
Miguel Cabrera went 4 for 5 with three doubles and drove in a run for Detroit, which has dropped the first three of a four-game series at Fenway Park.
With the Tigers trailing 4-3 in the seventh, Jon Lester was pulled after he fanned the final batter he faced -- Quintin Berry -- and Albers entered with a runner on second. Danny Worth reached on an infield hit before Cabrera looped one down the right field line that bounced off Gonzalez's glove as he attempted a sliding catch near the short wall, tying the game.
"After we tied it up, we got two real quick outs in that inning then they end up getting that run," Tigers manager Jim Leyland said. "That's tough."
The Tigers had built a 3-0 lead against Lester with a run in the first and two in the third before Boston rallied with four after two outs in the fourth against starter Drew Smyly.
"We knew the second time around what he had already," Middlebrooks said. "He showed us what he had so the second time around we knew what to expect."
The Red Sox entered the game leading the majors with homers (24) and extra-base hits (61) against left-handed pitching. After being held to just an infield single, they added to those numbers with their big fourth.
After Smyly got the first two batters on a fly to the track in center and a strikeout, Boston collected five consecutive hits -- highlighted by the two-run homers by Ortiz and Middlebrooks. Ortiz hit a shot into the center field bleachers -- his 12th of the season -- and Middlebrooks had a line drive into the first row of the seats above the Green Monster.
"You definitely want to keep it in the yard," Smyly said. "Just (the) two-run home runs, it's hard to win like that."
Lester gave up four runs, 10 hits, struck out seven and didn't walk anyone over 6 2/3 innings.
"We just haven't been able to get that big crusher hit," Leyland said. "We had some really good at-bats against Lester."
Smyly allowed four runs on eight hits in six innings.
Lester, coming off his second-worst start of the season when he lasted only four innings and gave up seven runs in a loss to Tampa Bay last Friday, gave up three straight singles to load the bases before Delmon Young's run-scoring grounder made it 1-0.
Worth had a sacrifice fly and Prince Fielder a run-scoring grounder to make it 3-0 in the third.
