Watching Blake Beavan get lit-up by the Houston Astros last night was apparently too much for the Mariners to let go without a response. They were already dealing with consecutive beatings handed to Brandon Maurer and can’t afford to give away two games out of every five before they even take the field.

So, today, according to Ken Rosenthal at FOX, the Mariners have gone out and reached a deal to acquire veteran starter Aaron Harang, 34. He was acquired by the Rockies from the Dodgers just five days ago and then immediately designated for assignment.

The Rockies were on-the-hook for $2.75 million of Harang’s salary and only acquired him so they could offload Ramon Hernandez’s $3.25 million contract to the Dodgers in that trade. Harang also has a $2 million buyout for 2014 attached to his deal, meaning he’s still guaranteed $4.75 million by the Mariners — hence the additional cash the Rockies sent over in the deal.

The Mariners, I’m told, have also thrown in a minor league pitcher not on the 40-man roster. The Rockies only want to clear money with this move. They don’t want to have to take a player off their current 40-man roster to accomodate any trade return for Harang.

Harang was 10-10 with a 3.61 ERA in 179 2/3 innings for the Dodgers last season. He’s here to help the Mariners get through their fifth starter spots until some reinforcements are ready down on the farm. Don’t expect anything big out of Harang. At this stage of his career, he’s just an arm the team hopes gets hit less hard than the beating its young guys are taking.

Erasmo Ramirez and Jeremy Bonderman are both a distance away from being MLB-ready and the Mariners, as mentioned, can’t keep giving games away two of every five days. The closest the team has to an MLB-ready replacement in AAA is Danny Hultzen, but the team may be loathe to expose him to the big leagues too soon.

What does this mean for the future of Beavan and Brandon Maurer? Well, the Mariners could go a few ways with this.
