Piazza takes knee to head while playing first

SAN JUAN, Puerto Rico -- New York Mets catcher Mike Piazza
found out there are collisions at first base, too.

Piazza, starting at first for the first time with the Mets, was
knocked down by the Montreal Expos' Peter Bergeron in the third
inning of Sunday's game.

Bergeron bunted to pitcher Tom Glavine, who threw to the outside
of first base. Piazza reached into foul territory in an attempt to
grab the ball, which got away, and he just avoided being run over
by Bergeron, who continued on to second.

Piazza appeared to be brushed in the head by Bergeron's knee and
stayed on the ground for about 30 seconds. But Piazza remained in
the game after being checked on by the team's trainer and manager
Art Howe.

Mets left fielder Cliff Floyd left the game in the first inning
because of a strained right thigh.
