Posey expected to sit out today after getting hit in the helmet

Backup catcher Nick Hundley is expected to get most of the action while Posey is on the disabled list.

The Giants won their home opener Monday against the Arizona Diamondbacks 4-1, but not before young starting pitcher Taijuan Walker threw a 94-mph fastball that hit star player Buster Posey square on the helmet and silenced the crowd. Athletic trainer Dave Groeschner sprinted toward the plate and Bochy was right behind. Posey was taken out of the game but he left under his own power and never lost consciousness.

Posey will be re-evaluated Tuesday, but manager Bruce Bochy said, "He's doing good, he's doing fine".

Posey (head) may be placed on the 10-day disabled list for precautionary reasons, Alex Pavlovic of NBC Sports Bay Area reports.

Justin Wilson (1-0) struck out one and walked one in the eighth and Francisco Rodriguez struck out two and allowed a hit in the ninth, earning his second save in three chances.

Moore helped salvage the day by holding the Diamondbacks to three hits in eight innings and, in the game's oddest moment, cleared the bases while batting in the fourth with a swinging bunt that traveled about 40 feet.

In fact, he made a point to reach out to Hundley in the third inning and said, "Make sure Posey knows - if he's alright, tell him I'm sorry".

Yasmany Tomas led off the fifth with his first home run of the season for Arizona.

Posey was hit in the back of the head with a fastball from Diamondbacks pitcher Taijuan Walker on Monday and is considered to possibly have a concussion.

"Well, it's one of the worst sounds you can hear in baseball, the ball hitting the helmet", Bochy said. He struggled to throw strikes at times, but he relied on the strikeout to get through his 5 1/3 frames.

"It's nearly an instinct to get up and shake it off", starting pitcher Matt Moore told the San Francisco Chronicle.

Cueto (2-0) was working on a three-hit shutout when he walked Jankowski with one out in the sixth and then allowed Myers' homer into the second-floor balcony on the Western Metal Supply Co. Posey said he was feeling well but the Giants weren't taking any risks. "We'll miss him", manager Torey Lovullo said. The last thing we wanted to do was get swept here and go 1-6 on this road trip.
