Jun 29 2025Cannon didn't factor into the decision Sunday against the Giants, allowing one run on three hits and three walks over three innings. He struck out four. ROTOWIRE RECOMMENDS: A lower-back strain kept Cannon on the shelf for over three weeks, and the 24-year-old was on a pitch count Sunday in his first start back. He threw just 69 pitches. Cannon has struggled with control this season, having walked three or more batters in six of his 13 appearances. He'll take a 4.59 ERA and a 55:24 K:BB through 66.2 innings into his next start, which is scheduled to come next weekend at Coors Field.
Jun 28 2025Manager Will Venable said after Saturday's game that Cannon (back) will start for the White Sox on Sunday against the Giants, Jack Ankony of SI.com reports. ROTOWIRE RECOMMENDS: Venable said pregame that Cannon could potentially start Sunday's game, but Venable left no doubt in the matter with his postgame comments. It'll be Cannon's first MLB appearance since being placed on the 15-day injured list June 3 due to a lower back strain. The 24-year-old made one rehab start, throwing three scoreless innings with Triple-A Charlotte on Tuesday. Cannon threw 48 pitches in the outing, so some sort of pitch limit should be expected.
Jun 23 2025Cannon (back) has been sent to Triple-A Charlotte to begin a rehab assignment, Bruce Levine of 670TheScore.com reports. ROTOWIRE RECOMMENDS: Cannon expects to require just 1-to-2 rehab starts with Charlotte before rejoining the White Sox's rotation. The right-hander has been sidelined for the entirety of June with a lower-back strain.
Jun 13 2025Cannon (back) is expected to go on a rehab assignment soon, Kyle Williams of the Chicago Sun-Times reports. ROTOWIRE RECOMMENDS: Cannon has been on the shelf since June 13 due to a back strain but is ready to begin ramping things up. It's unclear how many rehab outings he will need before being activated from the 15-day IL, but a late June return seems plausible.
Jun 3 2025The White Sox placed Cannon on the 15-day injured list Tuesday with a lower-back strain. ROTOWIRE RECOMMENDS: Cannon attempted to pitch through the injury Monday against the Tigers but didn't fare well, allowing five runs over just three innings. He'll be eligible to return June 18, but it's unclear at this point whether he will be ready to go by that date.
Jun 2 2025Cannon is expected to be evaluated for a lower-back injury over the next few days, Kyle Williams of the Chicago Sun-Times reports. He took his seventh loss of the season Monday against the Tigers, surrendering five runs on four hits and three walks while striking out five over three innings. ROTOWIRE RECOMMENDS: Cannon did his best to push through the back issue, but it was evident he didn't have his best stuff. "Bothered me a little bit out there, but I chose to go out there and try to compete, work through it a little bit," said the 24-year-old after the appearance, per Scott Merkin of MLB.com. "We'll kind of assess in the coming days and see if we can figure out a solution." It's currently unclear if he'll be able to make his next turn through the rotation, which would tentatively line up for Saturday against the Royals.
May 28 2025Cannon (2-6) took the loss Tuesday as the White Sox fell 6-4 to the Mets, coughing up five runs on nine hits and a walk over 5.2 innings. He struck out four. ROTOWIRE RECOMMENDS: Four of the hits off Cannon went for extra bases, including first-inning homers by Pete Alonso and Jared Young. It's the first time since April 10 that Cannon has been taken deep more than once, and the first time since April 21 the right-hander has been charged with more than three earned runs. Despite Tuesday's stumble, he'll take a respectable 4.15 ERA, 1.35 WHIP and 46:18 K:BB through 60.2 innings into his next outing, which is lined up to come at home early next week against the Tigers.
May 26 2025Cannon (back) will start Tuesday's game against the Mets, Kyle Williams of the Chicago Sun-Times reports. ROTOWIRE RECOMMENDS: Cannon was expected to toe the rubber for Saturday's matchup against the Rangers, but he was scratched due to lower-back tightness. Instead, the right-hander will make his next turn through the rotation Tuesday. Cannon is enjoying an impressive month so far, posting a 2.74 ERA and 1.13 WHIP with a 15:0 K:BB across 23.0 innings (four starts).
May 24 2025Cannon was scratched from his scheduled start Saturday against the Rangers due to lower-back tightness, Scott Merkin of MLB.com reports. ROTOWIRE RECOMMENDS: The White Sox are currently listing Cannon as day-to-day, so there seems to be a chance he avoids spending time on the injured list. Bryse Wilson will take Cannon's place on the mound Saturday against a Rangers offense that owns the fourth-worst OPS in the majors (.651).
May 18 2025Cannon (2-5) allowed four runs (three earned) on four hits and struck out three without walking a batter over five innings, taking the loss Sunday versus the Cubs. ROTOWIRE RECOMMENDS: Cannon was pitching well until the sixth inning, when he allowed three straight batters (two hits, one error) to get on base. He allowed the go-ahead RBI double to Pete Crow-Armstrong, and Steven Wilson allowed two inherited runners to score to spoil what had been a promising outing for Cannon. This was his fourth outing in a row in which he didn't walk any batters, and it was the first time he's fallen short of covering six innings since April 16 versus the Athletics. Cannon is now at a 3.76 ERA, 1.31 WHIP and 42:17 K:BB over 55 innings through 10 appearances (eight starts). He's projected to make his next start at home versus the Rangers.
May 14 2025Cannon tossed six scoreless innings Tuesday against the Reds, allowing just four hits and no walks while striking out six. He did not factor into the decision. ROTOWIRE RECOMMENDS: Cannon had his best outing of the season and was one strikeout off from tying his career high. He's now gone four straight outings of at least six innings while allowing three runs or fewer and hasn't walked a batter in his last 21 innings. He lowered his ERA to a 3.60 after the stellar effort and lines up to face the Cubs this weekend at Wrigley Field.
May 13 2025The White Sox will deploy Cannon as a bulk reliever behind opening pitcher Brandon Eisert in Tuesday's game against the Reds, Jack Ankony of SI.com reports. ROTOWIRE RECOMMENDS: Cannon has started in seven of his eight appearances on the season, but he'll enter Tuesday's contest out of the bullpen once Eisert exits the contest after likely working the first inning or two. Though he doesn't make many bats miss, Cannon has performed well over his last five outings, going 2-2 with a 3.30 ERA and 1.37 WHIP across 30 innings.
May 7 2025Cannon (2-4) took the loss Wednesday against the Royals after allowing two runs on nine hits and no walks in 5.1 innings. He struck out one. ROTOWIRE RECOMMENDS: Cannon certainly didn't overwhelm the opposition, as he tied season worsts with nine hits and one punchout, but he still managed to deliver his second consecutive quality start. While the right-hander has yielded a staggering 18 hits over his past two outings, that hasn't stopped him from throwing six innings of two-run ball in both appearances. Cannon hasn't lent a free pass in either of these starts. He'll still be tough to trust for fantasy purposes in his next scheduled start against the Reds at hitter-friendly Great American Ball Park, where he'll carry a 4.09 ERA, 1.45 WHIP and 33:17 K:BB across 44 innings.
May 2 2025Cannon (2-3) allowed two runs on nine hits and struck out five without walking a batter over six innings to earn the win Friday over the Astros. ROTOWIRE RECOMMENDS: Cannon was back in a starting role after operating as a bulk reliever in his appearance versus the Athletics last Saturday. He wasn't dominant, but just two of the nine hits he allowed went for extra bases, and they were back-to-back doubles in the fourth inning that led to the Astros' first run. Cannon's two wins have come over his last two outings, and this was his first quality start of the season. He's pitched to a 4.26 ERA, 1.45 WHIP and 32:17 K:BB across 38 innings over seven appearances. The 24-year-old is tentatively projected to have his next outing on the road in Kansas City.
