However, as stated above, this is more about his opponent than anything else. Cosart starts on Saturday against the Rays, a team that has compiled a .242/.316/.363 line this year. They have a .302 wOBA and 94 wRC+. Those aren't league-worst numbers, but they don't exactly scream of the 1927 Yankees, either. If you're looking for some last-minute help this weekend, Cosart can provide a dose. Both Jackson and Matsuzaka, though, are preferable.
