Dane Dunning SP

Dunning (elbow) was added to the White Sox's 40-man roster Wednesday.

Dunning is working his way back to health after undergoing Tommy John surgery back in March. He likely won't get back into game action until the middle of the 2020 campaign and will need some more time in the minors, as he's yet to reach Triple-A and has only made 11 starts at the Double-A level.

Dunning (elbow) threw a bullpen session Monday, James Fegan of The Athletic reports.

The session was Dunning's first since undergoing Tommy John surgery back in March. A typical recovery timeline would have him back in game action sometime during the middle of the 2020 season.

Dunning (elbow) has started light throwing out to 45 feet, Scott Merkin of MLB.com reports.

Dunning, who underwent Tommy John elbow surgery in March, will continue light throwing for the next two months. The right-hander is hoping to be throwing bullpen sessions by the time spring training arrives in 2020.

Dunning (elbow) underwent Tommy John surgery Monday, Daryl Van Schouwen of the Chicago Sun-Times reports.

Dunning was shut down with forearm discomfort earlier in camp, though it was decided surgery was necessary Monday. Coming off a sprained elbow to close 2018, Dunning will now face a long rehab process and miss the entire 2019 season and likely the beginning of the 2020 season as well.

Dunning (forearm) will meet with Dr. James Andrews on Monday to determine whether he'll need Tommy John surgery, James Fegan of The Athletic reports.

Dunning had recently been shut down for two weeks with what was originally diagnosed as forearm discomfort. It sounds as though the issue may be worse than that, and when Dr. Andrews is involved, the situation generally isn't good. A clearer prognosis should emerge following the visit.

Dunning (forearm) will not throw for the next 7-to-10 days, Daryl Van Schouwen of the Chicago Sun-Times reports.

Dunning was shut down earlier in the week after experiencing forearm discomfort. Fortunately, it was determined after further evaluation that the right-hander wouldn't require surgery; instead, he'll rest and receive treatment for at least the next week before picking up throwing thereafter. The White Sox figure to handle Dunning with care moving forward after a sprained elbow cut short his 2018 campaign.

Dunning is experiencing forearm discomfort, Bruce Levine of 670TheScore.com reports.

It's a discouraging development for Dunning, a player whose 2018 campaign ended prematurely in June due to a sprained elbow. Forearm issues are often the first diagnosis for an injury which is eventually deemed to be a serious elbow issue.

Dunning (elbow) is throwing pain-free, James Fegan of The Athletic reports.

Dunning's season ended in June thanks to an elbow sprain, but he's back to throwing side sessions with no pain after a lengthy period of rest and rehab. The young right-hander, who posted a 2.71 ERA, 1.19 WHIP and 10.4 K/9 across 86.1 innings (15 starts) in the minors prior to getting hurt, should be ready to go by the start of spring training barring any setbacks.

Dunning suffered a moderate elbow sprain during Saturday's start with Double-A Birmingham and will be placed on the minor-league disabled list.

The good news is that Dunning will not require a surgical procedure, but he will be shut for 6-to-8 weeks while undergoing a program consisting of rest and rehab. Following that timeline, he will begin a throwing program, so it's unlikely that the prospect will be back in action with Birmingham this season since the Rumble Ponies conclude their regular season Sept. 3 and the organization won't want to rush him back into action.

Dunning left his start for Double-A Birmingham on Saturday with right elbow soreness, James Fegan of The Athletic Chicago reports.

This is obviously a troubling development for one of the White Sox's top prospects. Dunning will undergo an MRI in the next few days to determine the severity of the injury. Even if everything checks out OK, Dunning will likely be out for a while as the organization has every reason to be cautious. Dunning has posted a 2.71 ERA, a 1.18 WHIP and a 100:26 K:BB in 15 starts between High-A and Double-A this season.

Dunning was promoted to Double-A Birmingham on Thursday, James Fegan of The Athletic Chicago reports.

Dunning has impressed through four starts with High-A Winston-Salem this season, compiling a 2.59 ERA, 0.95 WHIP and 31:3 K:BB across 24.1 innings, so the White Sox will see how he responds to the stiffer competition at Double-A.

Dunning allowed two hits and struck out eight over 6.1 innings for High-A Winston-Salem on Wednesday.

Dunning has come out strong for the Dash, having allowed one run while striking out 16 over 11.1 innings in two starts. The White Sox have several elite prospects, so guys like Dunning get lost in the mix. He pitched well at this level in 2017, and it shouldn't be too long before he's promoted to Double-A Birmingham.

The White Sox reassigned Dunning to minor-league camp Friday.

Dunning received a non-roster invite to spring training and allowed seven earned runs over nine innings with four strikeouts this spring. The 23-year-old earned the invite with stellar 2017 season between Low-A Kannapolis and High-A Winston Salem, delivering a 2.94 ERA and 168:38 K:BB over 144 innings (26 starts), and is likely to start the 2018 season at Double-A Birmingham.

Dunning has been invited to the White Sox's major-league camp this spring, James Fegan of The Athletic Chicago reports.

In his second year of pro ball, Dunning established himself as a future rotation piece by posting an impressive 2.94 ERA and 168:38 K:BB across 26 starts (144 innings) between Low-A Kannapolis and High-A Winston-Salem. Spring training should prove to be a good test for Dunning, who is expected to open the 2018 season with Double-A Birmingham.

Dunning allowed one hit while striking out nine in a seven-inning shutout for High-A Winston-Salem in his final start of the season Sunday.

Dunning retired the final 13 batters faced and brought his strikeout total to 168, 11th in the minor leagues. The 22-year-old right-hander made quick work of the Low-A South Atlantic League while pitching for Kannapolis, earning a promotion to High-A just four starts into the season. The advanced level was a bit more challenging, but Dunning finished 6-8 with a 3.51 ERA and 135 strikeouts over 118 innings after his promotion.

Dunning, 22, has a 3.03 ERA and 71:25 K:BB in 62.1 innings since being promoted to High-A.

Dunning hasn't skipped a beat since being bumped up a level. Opposing batters are hitting just .239 against him, and the 6-foot-4 righty has been inducing more than his fair share of groundballs. Dunning was a reliever in college but has shown no signs of struggling with his shift to the starting rotation.

Dunning was promoted to High-A Winston-Salem, Colleen Kane of the Chicago Tribune reports.

Dunning cruised through the South Atlantic League with a 0.35 ERA, two walks and 33 strikeouts over 26 innings for Low-A Kannapolis. He's the forgotten third pitcher in the Adam Eaton trade that brought the more heralded Lucas Giolito and Reynaldo Lopez back to Chicago, but has been the best performer of the bunch. Dunning isn't going to light up the radar gun, but he can locate the fastball, has a three-pitch mix and pounds the zone (69.5 percent of pitches are strikes).

Dunning was traded to the White Sox on Wednesday, FanRag Sports' Jon Heyman reports.

He was the third piece in a package that sent Adam Eaton to the Nationals. Dunning was used as a reliever at Florida due to the Gators' depth in the rotation, but he is a legitimate starting pitching prospect. He features a mid-90s fastball, a potentially plus changeup and a slider that could develop into a useful third pitch. The White Sox were reportedly quite high on Dunning during the draft process, so it is not surprising he was included in this deal. Look for him to be assigned to Low-A, with a chance to move quickly, as is often the case with pitching prospects in the White Sox's system. Lucas Giolito and Reynaldo Lopez headlined Chicago's return package.
