Olney On Jaso, Kubel, Upton

The latest from ESPN.com's Buster Olney…

• If the Mariners’ attempt to acquire Justin Upton had been successful, Seattle would have traded John Jaso to Oakland as part of the deal, Olney reports (on Twitter). Instead, Upton blocked the proposed trade and the A's acquired Jaso in a three-way trade with Washington.
• The Diamondbacks continue to weigh offers for Upton and Jason Kubel, Olney reports (Twitter links). The Diamondbacks want to deal one of the outfielders sooner rather than later and they feel as though there’s a good chance of getting “suitable value” for Kubel if they decide to deal him.
• Rival executives view the Orioles as a possible match for Kubel, Olney reports (Twitter links). In Olney's view the Rays are another potential destination for Kubel.
• The 2002 Braves and the 1995 Indians had some of the best outfields in baseball history, Olney wrote at his Insider-only blog today.
