Willy Garcia has surgery to repair broken jaw

BOSTON — Willy Garcia, who suffered a violent blow to the side of his head in a collision with teammate Yoan Moncada on Monday night, has a fractured jaw in addition to the concussion that put him on the disabled list.

The Sox announced Thursday that a CT scan taken Wednesday in Chicago on the right fielder revealed a fractured right jaw. Garcia had a plate inserted into his jaw Thursday and is expected to miss four to six weeks, which very well could mean his season is over.

Garcia and Moncada, playing second base, converged on Darwin Barney’s short fly ball near the right-field line during the sixth inning of a Sox 7-6 victory. Garcia attempted to make a sliding catch, and Moncada, trying to avoid contact by jumping over him, struck Garcia with his right knee. The crowd at Guaranteed Rate Field gasped when a replay showed the hard contact causing Garcia’s head to snap from side to side.

“From the initial injury, we thought it was [a concussion],’’ manager Rick Renteria said Thursday. All of us are happy that it wasn’t his skull. That would have obviously been much more serious. Not that the blow he took wasn’t serious, but he’s going to be OK.’’

Moncada was back in the Sox lineup against the Red Sox Thursday after missing two games.

Davidson still out

Matt Davidson, hit by a pitch from the Jays’ Marcus Stroman Tuesday, was out a second straight day with a bruised right wrist. Davidson still has swelling but said he had better movement in the wrist. He continues to receive treatment.

“I got hit pretty good in a sensitive area,’’ Davidson said. “There is just swelling we are getting out of there. And it is moving better as every day goes by. But it still doesn’t feel comfortable.’’

Renteria said Davidson is day-to-day, but it seemed almost certain he would miss at least one more game. Davidson, the team leader in home runs with 22, stood in on pitcher’s bullpen sessions trying to maintain some timing.

• Avisail Garcia (sprained right thumb) is on the trip and began hitting off a tee.

Sox’ farm system is No. 1

MLB Pipeline and Baseball America came out with their midseason farm-system rankings and rated the Sox No. 1 and No. 2, respectively.

The Sox climbed from third to first on the MLB Pipeline list, compiled by prospects guru Jim Callis, who had the Sox third during the preseason. The Sox have eight of the top 67 on his list: Moncada (1), outfielder Eloy Jimenez (7) right-hander Michael Kopech (12), outfielders Luis Robert (26) and Blake Rutherford (45) and right-handers Reynaldo Lopez (59), Lucas Giolito (60) and Dylan Cease (67).

The Sox also would have had the No. 58 player, Fernando Tatis Jr., but they traded him to the Padres in the deal that brought James Shields to the South Side.

The top 10 teams: Sox, Braves, Padres, Yankees, Rays, A’s, Phillies, Brewers, Astros, Dodgers.

Baseball America rates the Braves first, Sox second and the Phillies third.
