EDGE Analysis

Nathan, who is recovering from Tommy John surgury, is scheduled to pitch again for Triple-A Iowa on Wednesday. The Cubs may move him up by the weekend as a means of figuring out what the have heading into the Trade Deadline. Nathan last pitched Sunday, and struck out one batter over a scoreless inning.

Nathan (elbow) pitched one shutout inning at Triple-A Iowa on Thursday, striking out two batters along the way.

EDGE Analysis

Nathan has now thrown 7.2 innings between Double-A Tennessee and Triple-A Iowa while rehabbing his elbow. During that time he's allowed two runs, both of which were home runs. The Cubs have yet to say when they plan to end his rehab assignment, but the expectation is that Nathan could be joining the Cubs' bullpen in the near future.

Nathan (elbow) is eligible to return from the disabled list July 16, Carrie Muskat of MLB.com reports.

EDGE Analysis

Nathan has been pitching at Double-A Tennessee while rehabbing his elbow. Thus far, he's pitched 5.2 innings across six games, during which he's allowed two runs and struck out six batters. While his official return date has yet to be set, Cubs' Manager, Joe Maddon, has indicated that Nathan's performance at Tennessee is encouraging the team to believe the 41-year-old righty will be a solid contributor when he eventually returns.

Nathan (elbow) will begin his rehab assignment with Double-A Tennessee, Gordon Wittenmyer of the Chicago Sun-Times reports.

EDGE Analysis

Nathan signed a major league deal with the Cubs in mid-May, as has been recovering from Tommy John surgery that forced him to miss all of last season. The 41-year-old could be a huge boost to the club's bullpen if he can work his way back from the injury, and could join Chicago around the All-Star break if he is effective and everything goes according to plan.

Nathan (elbow) is working out at Chicago's Arizona complex, Patrick Mooney of CSNChicago reports.

EDGE Analysis

Nathan, who is returning from Tommy John surgery that forced him to miss the 2015 season, is still knee-deep into his rehab program. At 41 years old, age has to be considered a factor in whether he can return to big-league form again, but the veteran closer has had success in the majors as recently as 2014 when he saved 35 games for Detroit. Nathan working out in Arizona indicates that he's serious about making a major league return but that likely doesn't have a chance of happening until sometime after the All-Star break.

Nathan (elbow) signed a major league contract with the Cubs on Tuesday.

EDGE Analysis

Nathan is still in the process of recovering from Tommy John surgery, but the Cubs decided to take a flier on the veteran reliever and sign him for bullpen depth. The 41-year-old had been an effective closer, saving 35 games as recently as 2014, but it's unclear when (or if) he'll return to appear in the Cubs bullpen. The Cubs moved him to the 60-day disabled list to avoid making any moves to their current 40-man roster.

Nathan (elbow) continues to work out in hopes of pitching in 2016, Jon Heyman of CBS Sports reports.

EDGE Analysis

It was announced in February that Nathan would attempt to pitch again, and this serves as confirmation that his pursuit continues. It's not exactly clear where Nathan stands in his recovery, or where he may end up, but his workouts are reportedly going well, so he could still see action in an MLB game at some point this season.

Nathan (elbow) is progressing through workouts this winter with the hope of pitching in 2016, Fox Sports' Jon Morosi reports.

EDGE Analysis

At age-41, Nathan is recovering from his second career Tommy John surgery. Most likely, teams interested in acquiring his services will be eyeing a return after the All-Star break, as it's reasonable to think that he'll need more than the typical minimum 12-month recovery window to get back on the mound in game situations after having the surgery in late April.

Nathan's club option for 2016 was declined Tuesday.

EDGE Analysis

Despite his age (40) and his recent injury history (missed almost the entire season after undergoing Tommy John surgery), Nathan has went on record saying he will pitch again in 2016. If he's able to recover he could be a valuable bullpen piece for any team, but his fantasy value will likely be dependent on where he signs during the offseason.
