While acknowledging this as probably too much of a generalization, I think baseball games are won (or lost) by either pitching or hitting. Based on earned run average, I think that when a MLB pitching staff gives up more than four runs it did not do its job. During the Cub’s recent ten game winning streak their pitchers gave up more than four runs only once. Now the Cubs have lost three in a row, and in every one the pitchers gave up more than four runs. Worse, they have given up six or more runs in each game, therefore not giving their hitting much of a chance to win.

The Cubs do currently have a winning 17-12 record due to the fact that of the 24 games played in April, Cub pitchers held opponents to four are fewer runs in 16 games. It appears to be the case that the huge number of their pitchers on IL is catching up to the Cubs.

If the pitching trend continues and given how well the other teams in the NL Central are playing, the Cubs will end up with a losing record for the season and not make the playoffs.
