LOS ANGELES — Before Brandon Marsh went to the on-deck circle in the sixth inning at Dodger Stadium on Saturday night, Don Mattingly stopped him. “Give me a look,” Mattingly said to Marsh, which meant Philadelphia’s interim manager was thinking about pinch-hitting for his cleanup hitter and one of the few competent producers in his lineup. Marsh understood. So, he looked back after Bryce Harper had drawn a walk to load the bases.He saw Edmundo Sosa, his friend and teammate, coming out of the dugout Saturday night to replace him.“As a competitor, as a player, you want that at-bat,” Marsh said. “No matter how tough it is. … I would still like to have confidence in myself there, but you know, I’m riding with Donny. And we made the decision. And it worked out in the end.”But not at first. In the last 20 years, the Phillies had pinch-hit for their cleanup hitter in the sixth inning or earlier for a non-injury or non-blowout reason only two times. Sosa, facing lefty Alex Vesia, struck out on four pitches — and none of them were in the strike zone. The rally fizzled without a run. The Phillies still trailed, and the move reeked of desperation from Mattingly, who is desperate because his team cannot score runs.Then, in the eighth inning, Sosa batted against another lefty reliever with the tying run on base. He smashed a dramatic two-run homer to left field for what proved to be the game-winning runs.“Yeah,” Mattingly said. “I knew that was going to happen, right?”The 4-3 win over the Los Angeles Dodgers clinched a winning road trip to California, and it was an absurd baseball game. Mattingly knew the truth. “I guess, lucky right there,” he said. Sosa swung at two more pitches out of the zone to begin that eighth-inning at-bat. He should have never seen a pitch to hit from Tanner Scott, who had not permitted an earned run since April 24.He did. And he pimped it.
