Rival executives believe the Texas Rangers will make a trade for one of the "Tier 1" starting pitchers, like Milwaukee Brewers right-hander Zack Greinke and Philadelphia Phillies left-hander Cole Hamels, reports Buster Olney of ESPN.

They will be an intriguing entity in this summer's market, and some rival executives believe they will make a big play for one of the Tier 1 starting pitchers, like Zack Greinke or (perhaps) Cole Hamels.

While Olney says it’s "far too early to write off Roy Oswalt," he notes that the veteran has generated almost as many extra-base hits (14) as strikeouts (16). Also, due to the uncertainty surrounding Neftali Feliz and his contribution for the remainder of the season, Texas could pursue a front-line starter.

An executive that Olney spoke with said that the fact that 2012 could be Josh Hamilton’s final year with the Rangers could also factor into the club’s decision to "pursue a big move."

Olney concludes that really big moves, such as the Cliff Lee trade, have become part of the Rangers’ pedigree under general manager Jon Daniels.
