At the very least, consider FF.
Slowey's really struggled on the road this season, with an ERA of 6.11 (12 ER in his last 7.2 road IP). He's also 1-1 with an 8.56 ERA in his last three starts.
This Rzepczynski cat can pitch. He's a lefty who had a 3.67 ERA in 2009 and struck out 60 in 61.1 IP, only allowing 51 hits. This is his 2010 debut.
Not sure if I trust the Jays pen enough to take this one the distance, but FF might be worth seriously considering -- especially since the Twins have never seen him before.
