Getty Images supplies the following caption to this photo:Davey Lopes Lopes played for the Cubs from 1984-86.Even though at first glance, you might think that was a photo from the 1984 NLCS, I can definitively tell you it not. Why Because the Padres didn start wearing that style of road uniform until 1985.All right, so it from 1985 or 1986. Garvey played in all 12 Cubs/Padres games at Wrigley Field those two years, but we can eliminate the last series because Lopes had been traded to the Athletics right before that set began.That leaves nine games. Six of them were in early May and the ivy is not that full in early May.That leaves three games: Monday, July 8 https://www.baseballstoreonline.com/Brailyn_Marquez-298, 1985, Tuesday, July 9, 1985 and Wednesday, July 10, 1985.Lopes pinch-hit in the July 8 game and did not reach base. He didn play in the July 9 game.So this has to be from the July 10 game. Lopes played left field that afternoon and had a really good day  3-for-3 with a double, home run Jake Marisnick Pillow Cover, walk and three RBI.He doubled in the first inning, so it can be that at-bat. He walked in the second, but that pushed a runner to second base, so it would seem to me that he wouldn have been taking a lead where the pitcher would have thrown over in that plate appearance. He hit the home run in the seventh with a man on base. At the time, it tied the game. Keith Moreland followed with a homer to give the Cubs a 4-3 lead.The remaining at-bat was a single by Lopes with one out in the fifth, scoring a run. Here where the shadow gives you a clue. This is a July game, starting at 1:20, running 2:23, so it ended just before 3:45. The middle innings would have happened around 2:30-2:45 and the shadow in left field seems to be similar to what you see at that time of year.One of two things is being shown in this photo. Either it a throw over to keep Lopes close, or... he was doubled off first base when the next hitter, Moreland, hit a ly ball to shortstop . I inclined to think it the latter. Lopes had a very good year for the Cubs in 1985, hitting in 325 PA https://www.baseballstoreonline.com/Ildemaro_Vargas-316, with 11 home runs and 47 stolen bases in 51 attempts. To this day that the single-season record for steals for a player 40 years old or older . It also ranks as the eighth-most in a single season for any Cub since 1900.Lopes and Garvey were Dodger teammates for 10 seasons from 1972-81 and played in four together.
