SAN DIEGO (AP) — Jordy Mercer homered and matched a career high with four of Pittsburgh's 16 hits Monday night, leading the Pirates to a 10-3 romp over the San Diego Padres.
Neil Walker added three hits and three RBIs, and Josh Harrison also had three hits to help Pittsburgh win for the ninth time in 13 games.
Charlie Morton (2-7) tied a career best with nine strikeouts in five innings. He allowed two runs and three hits in winning for the first time in five road starts this year.
Three relievers finished the five-hitter after 4 hours, 4 minutes — the longest nine-inning game in Padres history.
Mercer scored four times from the No. 8 spot in the batting order and went 4 for 5 to raise his average 20 points to .219. He entered with one home run and seven RBIs in 146 at-bats.
Tim Stauffer (2-2) lasted only 2 2-3 innings, his second consecutive disappointing start since being inserted into the rotation because of elbow injuries to Andrew Cashner and Robbie Erlin.
The Pirates broke open the game with three runs each in the seventh and eighth. The big blow was Walker's two-run double in the seventh, propelling Pittsburgh to its sixth win in the last nine road games.
Four times in the previous six innings the Pirates loaded the bases but scored only one run. They stranded a season-high 16 runners.
The teams combined for 12 walks and six hit batters.
Through the first four innings, Morton didn't allow a run or hit — although the Padres reached on an error, two walks and two hit batters.
