Tigers finding a way to get it done

Sorry Sori: Back on April 22, Cubs outfielder Alfonso
Soriano(notes)
bruised his knee running into the outfield wall. He did not go on the DL,
though he said the left knee hasn’t felt the same since.
After going 0 for 4 Friday against
the White Sox, striking out three times, Soriano is batting just .231. He has
14 home runs, but just a .294 on-base percentage, appalling for a leadoff
hitter.
Ari Kaplan, the Cal Tech-trained
statistical analyst who has consulted for a number of teams and has his own
website, ariball.com, suspects that the knee injury may have caused
Soriano to change his approach at the plate, namely that he is swinging much
more at low-and-away pitches outside of the strike zone. Of the 45 times he has
swung at such pitches since being hurt, he has missed 33. Before his injury, he
swung and missed just once at a pitch low and away.
“An injury on the lower left side
[knee, leg, foot] does not necessarily limit a player’s power or bat speed at
the plate,” Kaplan observes. “However, players may make different mental
adjustments by shifting weight off the back foot differently, which can affect
one’s power, bat speed, and selection of pitch types and locations to swing at.
“In Soriano’s case, he stands close
to the plate with a wide stance that centers the plate. There is no negative
connection between this injury and his ability to drive the ball. Before the
injury, he pulled the ball down the left-field line, with a few fly balls to
short right. After the injury, he is spraying the ball more to all fields – but
they are fly balls and popups more often than before. The ball is carrying
more, but resulting in fly-ball outs instead of hits.
“Since the injury, he has been
hitting line drives nearly half as often [13 percent vs. 22 percent before] and
ground balls more [43 percent vs. 35 percent before].”
How are pitchers adjusting? Since
mid-May, Kaplan notes, they are throwing him fastballs more often [45 percent
vs. 40 percent] possibly thinking that he can’t catch up to those pitches. He
is seeing fewer sliders and changeups, which is counter-intuitive to Soriano’s
history of trouble with such pitches.
