So far in 2007:
Game 1: 3 Ks in 9 IP
Game 2: 3 Ks in 6 IP
Game 3: 2 Ks in 5 IP
Game 4: 4 Ks in 7 IP
Game 5: 1 K in 3 IP (injury shortened)
Game 6: 3 Ks in 6 IP
Total: 16 Ks in 36 IP or 4.0 K/9.
His K/9 the past three years...
Sheets has been underwhelming in general, but his K numbers have been particularly disappointing. We're six games in and he's yet to punch out more than 4 in any of his starts. Last year, he struck out 4 or fewer batters in only 2 of his 17 starts--one of those starts he lasted only 1 inning before leaving because of injury. In the other, he left with one out in the third after giving up 7 runs to Houston (he then went on the DL immediately after the start).
I read earlier that he was disappointed in/worried about his Ks, so it's not likely that he's making more of an effort to induce ground balls or play to contact (a la Halladay).
This trend is a bit of a concern, as so much of Sheets' value has historically been tied up in his big strikeout potential. With the exception of opening day (in which he was masterful, but still only K'd three), he's actually been pretty average. Going into the season, I assumed only injuries would prevent him from being an elite SP. What gives?
