The Browns may turn the New
York Yankees back this season and
cop the American league flag. but
the St. Louis team of 1924 stacks
up stronger by several victories than
that of 1.02:. which finished one
lone victory behind the Sew York:
era.
Sisler's boys showed their strength
recently whcn they ran through a
string of 13 game-3 with but two de-
teats.
Several big league clubs now have
or have boasted of. shifts in the
outfield and at first base, the play~
era being changed as righthandcrs
and southpaws pitch. Sislt-r has in-
troduced a. variation of this idea.
He has a third base shift. Robertson
a rookie. plays the far corner against
righthandcrs. Ellcrbc. who has had
considerabie experience the last
couple of seasons in the Brown in-
field. goes to thir-l against south-
paws.
The way the Browns are rumbl-
ing along these days lead: one to
believe that the Tigers and Indians
may find themselves out of second
money if the Yanks do cop. And
Sialer’s man right now seem to be
of championship caliber themselves:

And Hagen? “fell the date was
lucky for him last year so neither
