26 Shelby Miller SP

Miller (elbow) completed a live-batting practice session Wednesday, Steve Gilbert of MLB.com reports.

Miller had previously been limited to throwing side sessions, so the fact that he's now facing hitters amounts to a step forward in his recovery. The right-hander is still probably multiple weeks away from kicking off a minor-league rehab assignment, but remains on track to return from the 60-day disabled list at some point in June or July.

Miller (elbow) threw his sixth bullpen session Friday since undergoing Tommy John surgery in May 2017 and is aiming to return from the 60-day disabled list in June, Steve Gilbert of MLB.com reports.

Miller tossed 35 pitches Friday, estimating that he threw at about 80 percent effort. The righty noted that he's been pleased with how his curveball, fastball and cutter have looked during his sessions thus far, but he has yet to incorporate a splitter into his pitch mix. The Diamondbacks will shut Miller down from throwing for the next five days as part of a pre-planned rehab regimen, but he'll get back on the mound again late next week.

Miller threw his fifth bullpen session of the spring Tuesday, incorporating breaking balls for the first time, Jack Magruder of FanRagSports.com reports.

Miller is working his way back from May Tommy John surgery. The standard recovery timetable would see Miller returning to the big leagues at some point in June or July. He could be a factor down the stretch for the Diamondbacks and for fantasy owners, though with xFIPs of 5.06 and 4.84 in the last two years, he's both an injury risk and a performance risk.

Miller (elbow) was able to throw a 15-pitch bullpen session Tuesday, Jody Jackson of Fox Sports Arizona reports.

This marked the first bullpen session for Miller since undergoing Tommy John surgery last May. He is expected to miss the first couple months of the 2018 season while continuing his recovery, but there hasn't been any clear timetable for his eventual return at this point. Expect a better picture once he's able to increase activity.

Miller (elbow) was placed on the disabled list Monday, Jack Magruder of FanRagSports.com reports.

Placing Miller on the disabled list was a procedural move for the Diamondbacks, who had to make room on their roster for the newly-signed Jarrod Dyson. Miller underwent Tommy John surgery in May, and is currently without a timeframe for his eventual return. The righty started just four games last season, over which he threw for a 4.09 ERA and 1.45 WHIP.
