The Seattle Mariners have “checked in” with the San Francisco Giants and San Diego Padres about their available pitchers, tweets Jon Morosi of MLB Network.

The Mariners are just 2 ½ games out of the second wild-card berth and general manager Jerry Dipoto is believed to be shopping for starting pitchers. Seattle ranks 22nd in the majors in starter’s ERA and the rotation currently includes rookies Sam Gaviglio and Andrew Moore.

One available option on the Giants could be veteran Jeff Samardzija, who is generating a “fair amount of interest,” according to Henry Schulman of the San Francisco Chronicle.

As for the Padres, veterans Clayton Richard, Jhoulys Chacin and Trevor Cahill have been mentioned as possible trade bait. There also appears to be plenty of interest in Padres' relievers.
