Hoffman was diagnosed with a right shoulder impingement Thursday, Mark Sheldon of MLB.com reports.

EDGE Analysis

Hoffman was placed on the 10-day injured list Thursday, but his shoulder injury won't require surgery. The right-hander is heading back to Cincinnati to be further examined, and a better idea of his return timetable could come into focus once his visit with the medical staff is complete.

Hoffman (shoulder) was placed on the 10-day injured list Thursday.

EDGE Analysis

Hoffman left his start Wednesday against the Nationals with right shoulder soreness, and the issue is evidently serious enough to cause him to miss at least one start. His expected return date is not yet clear. The righty is pitcher better than usual this season after finally escaping Coors Field, but his 4.61 ERA and 1.59 WHIP are still not particularly impressive. Cionel Perez was called up in a corresponding move.

Hoffman exited Wednesday's start against the Nationals with right shoulder soreness, Bobby Nightengale of The Cincinnati Enquirer reports.

EDGE Analysis

The 28-year-old struggled with his command Wednesday and issued five walks before being lifted with the injury after 1.1 innings. Hoffman's availability for his next turn through the rotation is in question due to the injury.

Hoffman was removed from Wednesday's start against the Nationals with an apparent injury, Bobby Nightengale of The Cincinnati Enquirer reports.

EDGE Analysis

The 28-year-old threw only 20 of 46 pitches for strikes while walking five batters over 1.1 innings before exiting with the athletic trainer. It's unclear if the unspecified injury will affect Hoffman's next turn through the rotation.

Hoffman (3-3) earned the win Friday against the Brewers after tossing five innings of one-run ball, giving up two hits and four walks while fanning seven.

EDGE Analysis

Hoffman has given up at least one run in each of his nine starts this season, but at the very least he ended a streak of four straight outings allowing at least two runs while recording his first win since April 16. The right-hander has posted a 6.13 ERA this month, which is a marked increase of the 3.33 ERA he had in five April appearances.

Hoffman allowed five runs (two earned) on five hits and three walks with five strikeouts in four innings versus Colorado on Sunday. He did not factor in the decision.

EDGE Analysis

The 28-year-old got through three innings with little trouble, but Colorado struck for five runs in the fourth. Hoffman didn't help his cause much, as his throwing error led to a run. The right-hander has gone five starts without a win, and he's failed to reach the fifth inning in his last four outings. He has a 4.67 ERA, 1.53 WHIP and 32:18 K:BB across 34.2 innings. He lines up to face Milwaukee in next weekend's series.

Hoffman (2-3) took the loss Tuesday, allowing three runs on four hits and two walks over four innings as the Reds were downed 7-2 by the Pirates. He struck out four.

EDGE Analysis

For the third straight start, Hoffman failed to get past four innings as he tossed 46 of 75 pitches for strikes. The right-hander will take a 4.70 ERA and 27:15 K:BB through 30.2 innings into his next outing.

Hoffman (2-2) took the loss in Tuesday's 9-0 mauling at the hands of the White Sox, giving up four runs on five hits and a walk over 2.1 innings. He struck out four.

EDGE Analysis

The right-hander needed 63 pitches (36 strikes) to record only seven outs in his shortest start of the season. Hoffman will carry a 4.39 ERA and 23:13 K:BB through 26.2 innings into his next outing.

Hoffman allowed three earned runs on one hit and five walks while striking out three across four innings of work Tuesday against the Dodgers. He did not factor into the decision.

EDGE Analysis

Hoffman threw only 38 of his 73 pitches for strikes and walked multiple batters in both the first and fourth innings. He managed to hold the Dodgers scoreless through three innings, but led off his final frame with two walks and then surrendered a home run to Will Smith. Now through 24.1 innings on the campaign, Hoffman has maintained a solid 3.33 ERA but has only a 19:12 K:BB. He's projected to draw the White Sox on Monday for his next turn through the rotation.

Hoffman was charged with two runs (one earned) on four hits and one walk while striking out four over five innings in a no-decision against the Diamondbacks on Thursday.

EDGE Analysis

This one ended up a 14-11 Diamondbacks win in 10 innings, but the starters were effective through the first half of the game, with Hoffman getting the better of Taylor Widener. Hoffman was able to largely overcome the shaky defense behind him, lowering his ERA to 2.66 through 20.1 innings with the Reds. Hoffman threw 88 pitches in this game after reaching 91 pitches in his previous start. He has allowed just two homers on the year even with three of his four starts coming at home in Cincinnati. Up next is a tough road test against the Dodgers.
