His most recently throwing session Tuesday was a simulated game that featured two 15-pitch "innings" against A's hitters.

Parker is still in the process of rehabbing from Tommy John surgery, but still likely remains a ways off from returning in a full capacity. The fact that he didn't suffer any setbacks during bullpen and live hitting sessions is a good sign, however, and he continues to make progress towards a return at some point this season.

Parker's bullpen session went well Tuesday and he will face live hitters Friday, the Bay Area News Group's Carl Steward reports.

Parker (elbow) is projected to return to the A's in June, reports Jane Lee of MLB.com.

Parker's 2014 Tommy John Surgery was the second of his career and manager Bob Melvin noted on Sunday that the team would be particularly careful with Parker because of that. It is unclear what role Parker will have once he does return, but with the A's likely to take a large amount of caution with him, it is difficult to see him providing much fantasy value in 2015.

Parker has lost his arbitration case with the Athletics and will receive a one-year, $850,000 deal, Jon Heyman of CBS Sports reports.

The combination of Parker's 2014 season lost to Tommy John surgery and mediocre 2013 season likely cost him his case, in which he filed for a $1.7 million salary. This was Parker's first go-around in arbitration, and will definitely earn more next year after he's able to pitch this season.

Parker is set to undergo the second Tommy John surgery of his career on Monday. He won't be a factor again for the Athletics until the early part of the 2015 season. It's a brutal blow, but that good news is that he's still just 25 years old.
