Hmmm...looks like the Tigers were wise to this, and stacked their lineup with bench/platoon lefties - Josh Anderson, Jeff Larish and the switch-hitting Ramon Santiago, specifically. Not surprisingly, these three guys hit Cahill hard. Detroit offensive stats from the innings Cahill pitched:
C Granderson - L: 0-0 ; 2 BB ; 1 R
J Anderson - L: 1-2 ; 3B ; 2 RBI
C Thomas - L: 0-2
M Cabrera - R: 0-2
M Ordonez - R: 1-2 ; 2B ; 1 R
J Larish - L: 2-2 ; 2 R
G Laird - R: 1-2 ; 1 RBI ; 1 R
R Santiago - B: 1-1; 3B ; 1 RBI ; 1 R
A Everett - R: 1-1 ; 1 RBI ; 1 R
So what does this tell us? Lefties were a combined 4-7 against Cahill with two walks, two triples, 4 runs and 3 RBIs. OBP: .667 , SLG: 1.142 , OPS: 1.809. Righties were a combined 3-7 with one double, 2 RBIs and 3 runs (2 RBIs not counted here as they came off Casilla as inherited runners when Santiago hit a home run in the 3rd). OBP: .428 , SLG: .571 , OPS: .999. Cahill was bad, in general, in this start, but was particularly murdered by the lefties, a rather poor group of whom absolutely teed off on him.
Looking at Cahill's previous starts, this appears to be the first time that an opposing team really stacked its lineup with platoon lefties against Cahill, and the results weren't pretty. It also appears that Cahill was off, in general, yesterday, so I dunno what kind of trend this forebodes. Nevertheless, I wouldn't be shocked to see Trevor get a steady diet of lefty platoon hitters until he proves he can get those guys out, which probably isn't a good thing for his season going forward.
