When last we looked in on the Pittsburgh Pirates, they had gone 17-9 in the month of July, putting them in good position to end their streak of 19 straight seasons with a losing (below .500) record. Based on the Pirates' game-by-game log, I created the following chart. It shows that, as late as August 8, Pittsburgh had 16 more wins than losses (63-47) and needed to win only slightly more than one-third of its remaining games to clinch the 82 wins necessary for a winning record. (You can click on the graphic to enlarge it.)
Since then, however, the Bucs have won only 5 games, while losing 13. I would say Pittsburgh still has a good chance to finish above .500, but now the team must win a little more than 40% of its remaining games.
Working in the Pirates' favor, they have 13 games left against the Cubs (7) and Astros (6), two of the worst teams this year. The floundering New York Mets are also on the schedule for four games.
Will the Pirates finally achieve a winning season? I have created a poll in the right-hand column, so you can let us know what you think.
