First home victory since Aug. 1 and just their fourth since the All-Star break. I had forgotten what Randy Newman’s I Love L.A. sounded like. By now, you know Martin homered twice and the boys went 3 for 9 with RISP, and that all three hits came with two outs. You also know they improved to 61-59 and avoided falling to .500 for what would have been the first time since April 6, when they were 2-2. And that they stayed in fourth place, 6 1/2 behind the D-backs. What you do NOT know is something I uncovered before the game. Mark Sweeney’s baserunning gaffe in last night’s game happened after 9 p.m., our time, which meant it was after midnight Brooklyn time, which meant it happened on Aug. 15 Brooklyn time, which meant it happened on the 81st anniversary of the time the Dodgers committed one of the all-time baserunning gaffes at Ebbets Field when they got three men on third base at the same time, with two of them called out. All of which led to the famous joke: “The Dodgers have three men on base.” “Oh yeah? Which base?”
