I looked through the box scores and so far through 37 games, our DH is hitting .197 with an OBP of .269 with 12 RBI and 17 runs.
Assuming all my maths is correct, TCQ has seen ~24% of the PA and is hitting .151, .242 OBP 4 runs, 17 RBI; Jones ~21% of PA is .258, .303, 3 runs, 3 RBI; Kotsay with ~19% is hitting .080, .233, 3 runs, 2 RBI; Pierre ~19%, .296, .344, 6 runs, 0 RBI; PK 9%, .133, .133, no runs, no RBI.
I didn't look at how other teams DHs stack up, but I'm pretty sure those numbers have got to be at the bottom of the list.
