No, not that one.
This one.

We'll see, but I suppose it can't hurt. With Foulke on the DL for who knows how long, I guess they decided they needed a LOOGY after all.
RED SOX ACQUIRE LEFTHANDED PITCHER
JAVIER LOPEZ FROM CHICAGO WHITE SOX FOR RIGHTHANDER DAVID
RISKE
BOSTON, MA – The Boston Red Sox today
acquired lefthanded pitcher Javier Lopez from the Chicago White Sox in exchange
for righthanded pitcher David Riske. Executive Vice President/General Manager
Theo Epstein made the announcement.
Lopez, who is 2-1 with a 0.55 earned run
average with 12 saves in 26 appearances for Triple-A Charlotte of the
International League, will be in uniform for tonight’s game with the Twins in
Minnesota. He
will wear uniform #48.
The 28-year-old lefthander, who has pitched
in 171 major league games with Colorado and
Arizona, is
tied for fourth in the International League in saves and is tied for eighth in
appearances. He has held lefthanded hitters to a .171 (6-35) batting average and
has a groundball/flyball ratio of 64/25 (72%), the latter ranking second best in
the International League and fourth best in all of professional baseball (MLB
and minors) among pitchers with at least 30 innings
pitched.
Lopez has not allowed a run in his last 9.1
innings over eight appearances with the Knights beginning May 25 and has earned
saves in his last five and six of seven appearances.
Signed by the White Sox as a free agent in
December 2005, Lopez is 6-4, 6.09 with three saves in his major league career
with Colorado (2003-05) and Arizona (2005). In his
big league career, he has allowed just 22% (26 of 118) of inherited runners to
score while holding lefthanded batters to a .246 batting average.
The lefthander was 4-1 with a 3.70 ERA in a
career best and club rookie record 75 appearances with the Rockies in his rookie season in 2003. He issued just two
earned runs in his first 30 appearances that season. Lopez appeared in 64 games
with Colorado in 2004 and last season was 1-1
in 32 contests with the Rockies and
Diaamondbacks while also pitching in 27 games at Triple-A
Tucson.
A fourth round selection of Arizona in the 1998 First-Year Player Draft, Lopez was
picked by Boston
in the Rule 5 Major League Draft in December 2002. The Red Sox traded Lopez to
Colorado in
March 2003.
Riske is 0-1 with a 3.72 ERA in eight
relief appearances with the Red Sox this season. He was on the disabled list
from April 12-May 22 with a lower back strain. The righthander had been acquired
from Cleveland
in a six-player trade on January 27, 2006.
