The Seattle Mariners might be the latest team to make a serious pitch for Oakland Athletics right-hander Sonny Gray.

Rumor Central

Mark Feinsand of MLB.com cites a source who suggests Mariners GM Jerry Dipoto "might be preparing to make a run" at Gray, one of the top starting pitchers available with the trade deadline one week away.

"(Dipoto) is going for it these next two years. If he is going for it, he might as well go completely in," says a source, who, according to Feinsand, has "knowledge of the team's thinking."

The Mariners are 2 1/2 games behind in the AL wild-card race and have not been to the postseason since 2001. Dipoto has been proactive in an effort to end that drought, sending several prospects to the Miami Marlins last week for reliever David Phelps and another prospect, outfielder Tyler O'Neill, to the Cardinals for reliever Marco Gonzales.

A report last week said the Mariners have "checked in" with the Padres and Giants about pitching help.

One primary obstacle to any deal for Gray is the prospects the A's would ask in return. Feinsand says the Mariners would likely have to include outfielder Kyle Lewis, a first-round pick in 2016, in any deal for Gray, who is under club control through the 2019 season.

The Astros, Brewers and Yankees are among the other teams that have been linked to Gray.

The 27-year-old Gray, who missed the first month of the season with a strained shoulder, is 6-4 with a 3.66 ERA in 15 starts, including a 1.62 ERA over his past five outings.
