Buehler could be moved to the bullpen prior to his next scheduled start, Chris Cotillo of MassLive.com reports.

Buehler has struggled with his command all season, but his performance has gone even further downhill of late. He has a 6.5 BB/9 and a 1.72 WHIP across his last five starts, and he's failed to complete at least five innings three times in that span. Richard Fitts would be a candidate to take Buehler's rotation spot, as would Kyle Harrison, Payton Tolle or Connelly Early.

Lorenzen didn't factor into the decision Thursday against the Rangers, allowing four runs (three earned) on nine hits and a walk across 4.1 innings. He struck out six.

While Lorenzen's final line could've looked much worse, the right-hander still failed to make it through the fifth inning after throwing 89 pitches. Overall, it was a step backwards for Lorenzen after he held the White Sox scoreless across four innings in his previous outing, which was his first following a month-long stint on the IL. Lorenzen sports a 4.50 ERA through 20 starts (108 innings) this season with a 1.34 WHIP and 94:32 K:BB.

Corbin did not factor into the decision in Thursday's 6-4 loss to the Royals, allowing four runs on seven hits and two walks over 3.2 innings. He struck out two.

Corbin's struggles continued Thursday -- the left-hander has failed to make it through five innings in any of his last four starts, posting an 11.48 ERA in that span (13.1 innings). Overall, the 36-year-old Corbin sports a 4.61 ERA with a 1.41 WHIP and 101:42 K:BB across 24 starts (123 innings) this season. He'll look to get back on track in his next outing, currently slated for next week at home against the Angels.

Yankees manager Aaron Boone said Thursday that Yarbrough (oblique) will make at least one more rehab start, Max Goodman of NJ.com reports.

He's made two rehab starts thus far, with the last one coming with Triple-A Scranton/Wilkes-Barre on Wednesday, when he allowed two runs while striking out three over 3.1 innings. Yarbrough got his pitch count up to 50 in that outing and will continue to build up his stamina in case he's needed in the Yankees' rotation. As things stand right now, however, he might be destined for long relief once he rejoins the big club.

Urena (0-1) took the loss Thursday against the A's, allowing six runs on seven hits and two walks over five innings. He struck out three.

All six of the A's runs of Urena came in the second inning, when the right-hander allowed six consecutive men to reach base with two outs. The veteran Urena had been pitching well for the Twins prior to Thursday, allowing just three earned runs over 12.2 innings in his first three appearances. Overall, Urena sports a 5.00 ERA with a 1.47 WHIP and 20:13 K:BB across 36 innings between the Twins, Dodgers, Blue Jays and Mets this year.

The Astros activated France (shoulder) from the 60-day injured list and optioned him to Triple-A Sugar Land on Thursday, Matt Kawahara of the Houston Chronicle reports.

France has completed his rehab from shoulder surgery, but the Astros have elected to keep him at Sugar Land where he's been on a rehab assignment. The righty will provide rotation depth in the minors.

Bido earned the save in Thursday's 8-3 win over Minnesota, allowing a run on two hits while striking out four over three innings.

It's the first save for Bido in his three-year MLB career. The right-hander has been decent in a long-relief role of late, posting a 3.18 ERA across 17 innings in his last seven appearances. Overall, Bido sports a 5.37 ERA with a 1.58 WHIP and 49:25 K:BB through 65.1 innings this season.

The Red Sox recalled Fitts from Triple-A Worcester on Thursday.

Fitts has been used exclusively as a starter in the majors and minors this season, but the Red Sox will shift him to relief to see if his stuff might play up in shorter stints. The righty holds a 4.83 ERA and 34:13 K:BB over 41 innings during his time with Boston this season.

The Yankees signed Blackburn to a one-year contract Thursday.

Blackburn was recently cut loose by the crosstown Mets but has quickly landed on his feet with a new major-league deal. He has struggled during his time at the big-league level this season, posting a 6.85 ERA, 1.65 WHIP and 18:8 K:BB in 23.2 innings. Blackburn will presumably work in long relief for now and offers the flexibility to enter the rotation, should a need arise.

Hancock has moved to the bullpen at Triple-A Tacoma and allowed one run on two hits and one walk over one inning of work in his first relief appearance there Wednesday.

The bottom-line results weren't there for Hancock, but he averaged 97.4 mph with his four-seamer in the outing. That's a substantial velocity uptick from the 94.7 mph he's averaged this season during his time as a starter with the Mariners. It's not clear whether this is a permanent move to the bullpen for Hancock, but he could turn into a weapon in relief with his stuff playing up in shorter bursts.
