Suppan has made seven starts for us, with Game Scores ranging from 58 (his next-to-the-latest start) to 29 (his latest start). He's gone 35 innings in those 7 starts, although as pointed out above, he was limited in his first couple of starts since he'd been in the bullpen most of the year with Milwaukee; he went 8 2/3 innings in his first two starts, which means he's gone 26 1/3 in his last five - including six innings in each of his last two starts.
His peripherals are pretty bad, though, and the argument could be made that he's been lucky to do as well as he's done.
As for run support, the Cards have scored 16 runs in his 7 starts, while allowing 26 - 20 of those runs were charged to Suppan; six were charged to the bullpen.
So while it's true that Soup hasn't pitched particularly well for us, it's also true that he's gotten lousy run support - you aren't going to win many games averaging 2.28 runs per game no matter who is on the mound.
As for Hawksworth, he's also made seven starts - the first of which was his emergency start against the Dodgers on June 7. He joined the rotation for real on June 26 and in his six starts since then, has thrown 32 2/3 innings, posting Game Scores ranging from 57 to 24. he's pitched into the 80's or 90's in terms of pitch count in each of his last five outings, and was doing OK for awhile, but seems to have regerssed in his last two starts.
Run support: The Cards have scored 32 runs in Hawks' six starts since he joined the rotation, while allowing 31. Hawksworth has allowed 19 of those runs - including ten over his past two starts - while the bullpen allowed 12 (this includes the infamous Colorado meltdown in which Hawksworth allowed 2 runs while the bullpen allowed 10).
So Hawks has pitched better than Soup, and the Cards have scored more runs for him - and they've won 3 of his 6 starts since he joined the rotation (should have been four but for the meltdown) while they've only won 2 of Soup's 7 starts, again due as much to lousy run support as much as lousy pitching.
But - I am concerned about those last two starts by Hawksworth; he'd allowed just nine runs in his first four starts, but has allowed ten runs in his last two. That's not a good trend; indeed, it could be an indication that the league has "figured him out".
Either way, the sitatuion screams for us to get another starting pitcher, and I'm going to be terribly disappointed - but not a bit surprised - if the team decides to count on a Lohse comeback instead of making a deal. I almost hope Lohse is awful tonight in Memphis to remove that temptation.
