Most major league teams will be adding a players Saturday as the roster limit expands from 25 to 40.
The Seattle Mariners are one of the teams that has no plans to do so.
Seattle, a 9-1 loser in the opener of a homestand against the Los Angeles Angels on Friday, will wait until after the minor league season ends on Monday.
The one player the club had thought about bringing back right away, first baseman Mike Carp, was held out of a rehab game Wednesday with a flare-up of his groin problem, then played just five innings for Class AAA Tacoma on Thursday. It was his first game at first base after a couple of starts as the designated hitter. He was back at DH on Friday.
Manager Eric Wedge wants to have Carp play a full game at first base, which could happen Saturday or Sunday.
The other veteran who might have been targeted for a quick return to the big leagues, right-handed pitcher Shawn Kelley, was hit by a ball on his elbow Wednesday. While not thought to be seriously hurt, Kelley will get some time to heal.
When they add to the roster, the Mariners are likely to promote several other position players who have been with the big-league club this season, including outfielder Casper Wells, first baseman/third baseman Alex Liddi, outfielder Carlos Peguero, and several pitches, among possibly Erasmo Ramirez, Hector Noesi, Chance Ruffin and Forrest Snow.
