We could have started Walter, who seems like a better option that 2 pen games every 5 days, but for some reason they put their trust in Jacquez and Llovera, before them it was Ort and Brasier, and ...
The one bright spot of this season was the play from multiple recent prospect call-ups: Bello, Casas, Murphy, Wong and Duran (not so recent on Jarren, but his maturation was.)
We also had some minor or brief help from the likes of Bernardino, EValdez and others.
We've used 28 pitchers, this year, not counting Reyes. We've used 23 over 6 IP and 20 over 11 IP. We've seen so many hit the IL, some predictable, that I'd need a couple pages to list them all.
It certainly a big reason we are struggling has been the amount of pitchers who have sucked or underperformed expectations, but we have seen 14 pitchers wtih 6+IP have an ERA under 4.60 (Sale at 4.58 was doing much better before going back on the IL.)
13 pitchers with 6+ IP have ERAs under 4.20, including 5 of our top 6 IP pitchers:
3.79 Bello (102 IP)
4.19 Pivetta (92)
3.62 Crawford (82)
5.05 Houck (68)
2.82 Wink (61)
9 of our top 13 pitchers by ERA were under 4.19.
8 of 13 below 3.80
7 of 13 below 3.63
The killers have been:
5.05 Houck (5th in IP)
4.58 Sale (7th, although he was coming around)
7.04 Kluber (8th)
5.23 Whitlock (9th)
These guys were widely viewed as among our best 4-5 starters going into the year. It's rather remarkable we have gotten this far with those results, and I bring this up to point to the idea that pitching depth from the farm has actually been a strength, not the weakness you claim it is.
Other stinkers down on the list of zIP:
5.40 Bleier (14th
6.26 Ort (15th)
7.29 Brasier (17th)
5.85 Jacques (18th)
7.36 Garza (19th)
6.55 Joely (21st)
That's about 120 IP of horrific pitching. Although some were mop-up innings, and 120 IP is only 12% of all IP, I have to think these 6 lost more than just a few games for us.
I'm not going to blame the need to use these guys on injuries, but one could. I do think we stuck with a few way longer than we should have.
The major reason our staff has sucked is those top 4 underperforming pitchers, which may wrongly include Sale, due to his first 3 starts. Many who took up the slack of those struggling pitchers, carried this team. It was our pitching depth, including the rise of our middle/long relief pitchers, who have helped us stay above .500, this year.
IP Rank Pitcher ERA
2. Pivetta 4.19 (has really improved since April)
3. Crawford 3.62
4. Paxton 3.60
6. Wink 2.82
10. Bernardino 2.72
11. Jansen 3.06
12. Martin 1.53
13. Murphy 1.59
16. Schreiber 3.57
20. Walter 3.07
6 of these 10 were considered "pitching depth" on opening day: Paxton, Crawford, Wink, Bernardino (added later), Murphy and Walter..
Although Murphy and Walter's sample sizes are rather small (43 IP combined), they have done a fine job when used and may help in the next 2 months.
