Otherwise, he will just continue to tease the Red Sox Nation with his displays of power as a right-handed batter.

Carlos Guillen has played for two teams over the past five seasons, but one thing he brought to Detroit from Seattle is his inability to match his left-handed production on the right-handed side of the plate. While the gap between his two OPS's is not as glaring as some of the others on this late, there is no denying the 12% decrease.
There is no huge discrepancy in any one category of Guillen's splits, but the accumulation is enough to warrant him putting his switch-hitting career on hold indefinitely.

As RHB: .386 OBP/.493 SLG/.879 OPS in 515 at-bats
Ray Durham barely made this list, coming in at a 10% differential, but working under the logic that what he did over the past 2,097 at-bats is probably indicative of his split for his career, maybe his career numbers would be higher than they are.
It is probably too late to convince him to stop his switch-hitting now; maybe someone should have told him to stop when he first began.
