Oliver was 2-3 with a 6.44 ERA in 18 games this year, including
eight starts. The left-hander hasn't pitched since June 30, the
longest layoff of his career not related to an injury.
Opponents were hitting a lofty .319 against Oliver. He's allowed
91 baserunners in 56 2-3 innings.
Houston general manager Gerry Hunsicker, in Arizona for a
two-game set against the Diamondbacks, welcomed the addition. Mike
Gallo was the only left-hander in the bullpen.
"It's always good to add another lefty," Hunsicker said.
"Some of the teams, looking ahead at who we have to play, have
some good left-handed hitters. That's been one of the weaknesses of
"Gallo has not been as effective as he was a year ago, and
maybe this will take the pressure off him," he said.
Oliver is set to join the Astros on Friday when they host
Milwaukee. Hunsicker said he might wait until then to make a move
to clear a roster spot for Oliver.
"We're going to need some time to decide," Hunsicker said.
Oliver, 33, is 86-79 with a 5.08 ERA since starting his major
league career in 1993 with Texas. He's also pitched for St. Louis,
Boston and Colorado.
Wright, selected by Colorado in the first round of the 1993
draft, signed with the Rockies for the rest of the season. He went
8-6 with a 4.21 ERA in 18 starts for the Royals' Triple-A Omaha
farm club this year.
"It's just awesome to be back here," Wright said. "I've got a
lot of friends still here and a lot of friends that I've played
against. So it's pretty exciting."
Wright went to spring training with the Chicago Cubs as a
non-roster invitee before signing a minor league contract with the
After he was released Wednesday, he flew to Los Angeles and
underwent a physical, then had a bullpen session Thursday before
Colorado's 4-2 loss to the Dodgers. He is scheduled to start
Saturday night at Arizona in place of right-hander Denny Stark, who
was placed on the 15-day disabled list Tuesday because of a groin
"If we were going to have a tryout, we would have had it
somewhere else. We wouldn't have had it in the bullpen at Dodger
Stadium," manager Clint Hurdle said with a grin. "If he doesn't
fall down, he'll start Saturday."
Frederick was 3-2 with five saves and a 0.99 ERA in 20 games at
Syracuse. Before that, he went 2-0 with one save and a 1.27 ERA at
New Hampshire of the Double-A Eastern League, striking out 26 and
walking five in 21 1-3 innings.
File, brought up from the minors in June 3, was 0-0 with a 5.48
ERA in 14 games with Toronto.
File gave up a three-run homer to Gary Sheffield on his first
pitch after relieving Wednesday night in the Blue Jays' 10-3 loss
to the New York Yankees. He was charged with two runs and six hits
in 2 1-3 innings.
To make room on the 40-man roster, Toronto transferred catcher
Bobby Estalella from the 15-day disabled list to the 60-day DL.
Durbin began the season with the Indians and went 3-4 with a
10.70 ERA in 10 outings, including two starts.
The 26-year-old was sent to Buffalo on May 29. In nine starts
for the Bisons, he had a 3-3 record and 3.46 ERA.
Robertson, acquired from the Houston Astros for two minor league
outfielders in a trade just before the season began, is going to
Buffalo for the third time this year.
In two stints in Cleveland this season, he had a 12.21 ERA in
eight relief appearances.
Right-hander Craig Dingman was optioned to the Mud Hens to make room for Patterson on the 25-man roster.
Patterson had been placed on the 15-day disabled list June 28
with bursitis in his right shoulder. In 32 games with Detroit this
season, he is 0-4 with a 3.98 earned run average and two saves.
Dingman was 2-1 with a 5.03 ERA in 15 games for the Tigers.
Sanchez went 0-2 with a 7.53 ERA in three starts for the Reds,
who designated him for assignment Sunday. He cleared waivers but
refused an outright assignment to Louisville.
Sanchez has also pitched for Florida, the Cubs and Colorado. He
was part of a move that backfired on July 2, when the Reds called
him up from Louisville to start the first game of a series against
the Cleveland Indians.
The Indians were only 9-17 against left-handers at the time but
rolled to a 15-2 victory by piling up nine runs in the first five
innings off Sanchez and left-hander Mike Matthews.
