In Pittsburgh, Jim Morrison's two-run single in the ninth inning beat Los Angeles and gave the Pirates their 10th victory in 11 games.
The Pirates, leaders in the NL East, were 6 1/2 out less than two weeks ago.
In the ninth, Lee Mazzilli was safe on shortstop Bill Russell's throwing error. Two outs later, Bill Madlock singled off Steve Howe (3-5) for his 1,500th career hit. Jason Thompson walked, loading the bases.
Morrison, who'd already had two hits, pulled Howe's first pitch foul deep down the left field line. Then he hit a liner into left field. The third base coach, Joe Lonnett, didn't hesitate to send Madlock, and the throw was up the first base line.
"Sure, I wanted him to send Madlock," Manager Chuck Tanner of the Pirates confirmed. "If it's the tying run, I say no. But if it's the winning run, I say bring him."
When Madlock scored, Howe kicked his glove 30 feet into the air.
"It was a fast ball, but it wasn't where I called it or where I wanted it," Dodgers' catcher Steve Yeager said of Howe's final pitch.
Morrison, a utility player, is hitting .364.
