ANAHEIM, Calif. —
Alvarez led off the 10th against Jepsen (0-2) with a double to center field over Trout’s head — seven innings after Trout had shifted over from left after an injury to Peter Bourjos.
A pair of one-out walks, one of them intentional to Walker, loaded the bases and brought up Travis Snider. He promptly lined a single to left that bounced over Shuck’s head for an error and all the way to the fence as all three runners scored.
“When those guys get guys on base, they take advantage. That’s why they’re playing as well as they are,” Jepsen said.
Grilli closed it out despite giving up five hits, including RBI singles by Alberto Callaspo, Shuck and Brendan Harris. The right-hander finally ended it by striking out Trout with the potential tying and winning runs at third and second.
“We pushed all the chips in and got what we needed to get from our guys — and at the end of the day, the gunslinger got it done,” Pirates manager Clint Hurdle said.
Mark Melancon (2-1) pitched a perfect inning for the win.
Pittsburgh starter Charlie Morton was charged with six runs — three earned — and four hits through 5 2-3 innings in his third start of the season. The right-hander missed the first 65 games while recovering from elbow surgery last June.
Pirates catcher Tony Sanchez, the team’s No. 1 draft pick in 2009, went 1 for 4 in his major league debut — as the designated hitter.
His first time up he hit a ground-rule double against Joe Blanton that struck the 18-foot wall in right field halfway up and became wedged at the bottom of the out-of-town scoreboard. The ball remained there until the end of the half-inning, when a maintenance worker climbed a ladder and plucked it out before giving it to Pirates right fielder Garrett Jones.
