The Yankees placed Cruz on the 15-day injured list Monday with a left oblique strain.

Cruz injured his oblique while warming up with a medicine ball in the weight room Sunday, Bryan Hoch of MLB.com reports. He'll undergo an MRI on Monday to determine the severity of the strain. Geoff Hartlieb was called up from Triple-A Scranton/Wilkes-Barre to take Cruz's spot in the bullpen.

The Athletics optioned Ferguson to Triple-A Las Vegas on Monday.

With nine holds and one save over his 36 appearances. Ferguson had been serving as one of the Athletics' higher-level relievers this season, but he'll end up losing his spot on the 26-man active roster after a rough June in which he turned in a 15.58 ERA, 2.54 WHIP and 10:8 K:BB across 8.2 innings. The 31-year-old righty will give up his spot to righty Justin Sterner, who was recalled from Las Vegas.

The Athletics recalled Sterner from Triple-A Las Vegas on Monday.

Sterner was unscored upon in 24 of his first 25 appearances in the majors this season but was sent down earlier this month after allowing nine runs (eight earned) across his last two innings. He could work his way back into some high-leverage appearances but will likely be used in the middle innings initially.

The White Sox outrighted Palisch to Double-A Birmingham on Sunday.

Palisch made one appearance for the White Sox earlier this month before being optioned to Birmingham, allowing two earned runs over an inning of work in his major-league debut. He's now off the White Sox's 40-man roster but will remain in the organization.

Kahnle worked around a hit to toss a scoreless eighth inning and earn a hold in Sunday's 3-0 win over the Twins.

After Detroit starter Tarik Skubal dazzled across seven scoreless innings, Kahnle served as the bridge to Will Vest, who ultimately secured his 13th save of the season in the ninth. Kahnle now has 11 holds this year to go along with eight saves of his own. The veteran righty also has a stellar 1.77 ERA and 0.79 WHIP through 35.2 innings. While Vest is the team's top closer for the moment, Kahnle isn't far behind, and his high-leverage role and strong ratios give him standalone fantasy value.

Vest struck out one over a perfect inning to earn the save in Sunday's 3-0 win over the Twins.

Vest retired the side on a tidy eight pitches (six strikes) to earn his first save since June 12 versus the Orioles. He had a pinkie finger injury between those saves, which led to a blown save June 15 versus the Reds, but he avoided the injured list and has since turned in three scoreless innings. Vest is up to 13 saves, two holds and three blown saves while posting a 2.37 ERA, 0.95 WHIP and 42:10 K:BB across 38 innings. Vest continues to hold an edge for saves over Tommy Kahnle, who worked the eighth inning Sunday.

Jansen allowed a run on two hits and a walk while striking out one over one inning to take a blown save in Sunday's 7-4 extra-innings loss to Nationals.

Jansen hadn't pitched since June 24, which was his return from a pectoral cramp that shortened his appearance the day before. Despite being fresh, the Nationals were able to scrape together the tying run with a Jacob Young RBI single in the ninth inning. This was Jansen's first blown save of the year -- he had converted his first 15 save chances, though he's occasionally struggled in non-save situations. The veteran closer is at a 4.40 ERA, 1.36 WHIP and 26:11 K:BB over 28.2 innings this season. Jansen has logged 25-plus saves in every full-length campaign since 2012, so one blown save is not going to be enough to cost him his role.

Hader picked up the save Sunday against the Cubs, striking out one during a perfect ninth inning.

Hader notched his fifth save over the last seven days, vaulting him into a tie with Robert Suarez for the most saves in MLB. In his last 14 appearances, Hader has a 1.98 ERA and a 22:1 K:BB across 13.2 innings.

Hoffman struck out the side in a perfect inning to earn a save over Boston on Sunday.

Hoffman made quick work of the Red Sox in the ninth inning, punching out the side on 14 pitches to finish the 5-3 win. He's now converted 18 of 22 save chances this season and picked up his first since June 10. Hoffman has produced an impressive 48:10 K:BB through 34.1 innings despite a 4.98 ERA.

VanWey (undisclosed) struck out a batter and allowed no hits and no walks over a scoreless inning of relief for Triple-A Sugar Land on Saturday after being reinstated from the 7-day injured list.

VanWey was out of action for Sugar Land for about a month before he was cleared to rejoin the Triple-A bullpen. The 25-year-old reliever was previously up with the Astros earlier this season and gave up six earned runs on 15 hits and three walks over 8.2 innings.
