After last night’s complete game shutout, Ryan Franklin has his ERA back down to 5.03. He’s going to reach 200 innings for the second straight year, and if he can finish the season with an ERA under 5.00, the M’s might be able to deal him.
He’s got some pretty bizarre home/road splits, though. Take a look at this:
Split ERA IP H R ER HR BB SO Home 3.92 85.0 82 41 37 16 32 51 Away 6.01 97.1 122 66 65 15 26 39
Obviously, he’s getting a huge boost from Safeco Field, which masks the fact that he’s a replacement level pitcher. But at home, he’s a three true outcomes pitcher, giving up lots of walks, lots of homers, and posting a decent enough strikeout rate. On the road, he’s the antithesis, throwing strikes, not missing bats, and giving up less longballs.

These are pretty bizarre splits. It doesn’t appear that he’s getting a boost from Safeco as much as he is from his defense at Safeco. The league average batting average on balls in play is about .300, so Franklin’s essentially getting a 3 % boost in not allowing hits at home. Whether that’s a park factor or the defense simply having a home field advantage, I have no idea.
Last year, Franklin was the beneficiary of tremendous defense behind him. This year, he’s gotten similar benefits but only while playing at home. When the team leaves Seattle, the defense has been league average, and he’s been exposed as a pitcher who relies completely on the contributions of his teammates.
In reality, the huge splits are probably explained away by sample size noise that would filter out over time, but it’s still interesting to me.
