SAN DIEGO — The Indians and the Tigers have emerged as the most aggressive teams in talks with the Rockies about their ace pitcher, Ubaldo Jimenez. Of course, the Rockies want to extract a price that thus far several teams have decided not to pay.

For a time this week the Reds were the most prominent rumor, but starting pitchers Homer Bailey and Travis Wood, and either top catching prospect Devin Mesoroco or 100 mph-plus mph lefty Aroldis Chapman was too rich a ransom for a team below .500. The Yankees and Red Sox have made inquiries, and how aggressively you believe depends on which tweet or report you trust most.

The latest report from Fox Sports’ Ken Rosenthal has the Tigers willing to include righty prospect Jacob Turner, with Major League pitchers Rick Porcello and Max Scherzer being mentioned as possibly heading to the Mountains. The Indians have talked about not being willing to mortgage the future. However, there are at least indications that two prized pitching prospects, lefty pitcher Drew Pomeranz (at Double-A Akron) and righty pitcher Alex White (at Triple-A Columbus, but headed to Akron on a rehab assignment for a right middle finger injury) are in play. The Indians will not deal prized prospects for rental players, but Jimenez would be under club control through 2014.

The Rockies have shown no inclination to come down on their high price of Major League pitching and a top-of-the-line young player or prospect.

Jimenez is set to pitch for the Rockies on Saturday against the Padres.

In other trade-related news, the Rockies have been willing to discuss everyone except shortstop Troy Tulowitzki, outfielder Carlos Gonzalez and first baseman Todd Helton. Right fielder Seth Smith, who has proven to be a solid gap-to-gap hitter against right-handed pitching, is drawing the interest of multiple teams. The Rockies also are expected to see if they can find a taker for onetime top Draft pick Ian Stewart, a third baseman having a woeful offensive year.
