AL West Notes: Astros, Walker, Ackley, Mariners

Astros general manager Jeff Luhnow and his staff have narrowed their list of possible selections for the first pick in this year's Rule 5 Draft to roughly 10 players, writes Evan Drellich of the Houston Chronicle. One possibility on their list is Pirates right-hander Zack Thornton. The 25-year-old pitched to a 2.63 ERA with 10.8 K/9 and 1.4 BB/9 across three levels in 2013, topping out at Triple-A. Here's more out of the AL West in the midst of the calm before the storm that is the Winter Meetings…

• Two general managers told Jon Heyman of CBS Sports that they wouldn't part with Taijuan Walker in a package to land David Price (Twitter link). Last week, it was reported that the Mariners could push for Price but that Walker would need to be included in any trade.
• The Mariners have received a lot of interest in Dustin Ackley, tweets Jon Heyman of CBS Sports. As Heyman notes, Ackley had a solid finish to his 2013 season, batting .290/.360/.412 over his final 65 contests.
• Heyman also tweets that the Mariners' targets include David Price, Nelson Cruz, Joaquin Benoit and Corey Hart. Hart was drafted by General Manager Jack Zduriencik when Zduriencik was with the Brewers.
• The record for the highest payout through the arbitration process is $10MM, but one person familiar with the process tells Bill Shaikin of the Los Angeles Times that Angels outfielder Mike Trout could get $15MM in his first go 'round through arbitration, $20MM in his second year, and $25MM in his third trip through the process.  Even for a star of Trout's caliber, those numbers seem lofty.
