Notes: Scheppers ahead of schedule

ARLINGTON, Texas -- Tanner Scheppers threw a bullpen session Friday and is ahead of schedule in his recovery from elbow issues that plagued him last season, according to Texas Rangers GM Jon Daniels.

Scheppers, who was the club's opening day starter, didn't return in the 2014 season after being diagnosed with an inflamed right elbow in early June.

Scheppers was one of the Rangers' better setup men in 2013 but was moved to the rotation in spring training. He started four games before shifting back to the bullpen -- where he will find himself in 2015 -- and finished his season 0-1 with a 9.00 ERA in 23 innings.

Lewis negotiations ongoing: Daniels said the club has exchanged contract numbers with the agent for free agent Colby Lewis. Lewis and the club both appear open to reuniting. Lewis finished 10-14 last season and was much better in the second half, showing the club he was fully recovered from hip and elbow surgeries.

Darvish MRI: Rangers ace Yu Darvish will return to the U.S. in November for an MRI on his elbow. Darvish made his last start on Aug. 9 and was shut down for the rest of the season because of mild inflammation. If all goes well with the MRI, Darvish will resume his normal offseason pitching program.

Coaching staff update: The Rangers will try to finalize the coaching staff in the next two weeks. Daniels said he expects the staff to be in place before the GM meetings, which are in early November. Jeff Banister has met with pitching coach Mike Maddux, hitting coach Dave Magadan and bench coach Tim Bogar about their statuses for 2015. Magadan has met with two other clubs about employment, and Bogar is trying to decide if he remains whether he will be a good fit. Maddux would like to stay with the Rangers. Banister remained on the Pirates' staff in 2011 after he was passed over for their managerial gig in favor of Clint Hurdle.
