So I went through each game and pulled the starters' numbers. Wins and losses are the Astros actual wins/losses.
Here are my findings:
Month W L WHIP ERA K/BB
April 8 19 1.74 6.08 1.62
May 10 18 1.63 5.23 1.34
June 12 15 1.19 3.09 3.29
July 6 18 1.50 5.04 1.34
August 8 21 1.39 4.19 1.76
September 5 5 1.30 4.16 1.95
Our starters' average strikout to walk ratio is an awful 1.75. For reference, Yu Darvish sits at 3.67 and Max Scherzer sits at 4.48.
As you can see, the Astros most competitive month was June, and it was mainly due to the starting pitching. In June, the starting pitching was very good, with a K/BB ratio of 3.29. Unfortunately, this doesn't tell us much as the starting rotation included Bud Norris, Lucas Harrell, and Erik Bedard. Lyles was 3-4 with a 3.20 ERA for the month however.
With June being the outlier, we can see an improvement trend. Hopefully we'll see this trend continue for the duration of the season and into next. I think the key indicator is the K/BB ratio. If they can keep driving that up, I think we'll see a vastly improved team next year.
Since August 1st, the starters Lyles, Cosart, Obie, Peacock, Clemens, and Keuchel have an ERA of 3.54, a WHIP of 1.27, and a K/BB of 1.95 (I took out the trash starts of Harrell and Bedard). While these numbers don't exactly jump off the page, I think they are pretty competitive for being a rotation of rookies.
Anyways, I was just interested in seeing how the Astros starters were doing this year. Hope this provides some key info. These numbers might not be 100% correct...I keyed in the data myself last night.
