BALTIMORE — Grady Sizemore will never forget his first opening day with the Boston Red Sox.

His teammates, however, can’t wait to put the memory of the game behind them.

The defending World Series champion Red Sox failed to capitalize on several scoring opportunities, and a home run by Sizemore wasn’t enough to prevent a 2-1 loss to the Baltimore Orioles on Monday.

After missing two seasons recovering from knee surgery, Sizemore, an Everett native, marked his return from a 922-day absence with a second-inning single for his first hit since September 2011. The three-time All-Star for Cleveland later hit his first homer since July 15, 2011, which also came at Camden Yards.

“Today was very exciting,” Sizemore said. “I couldn’t wait to get to the ballpark.”

The single was particularly gratifying, because it came on his first at-bat.

“Having gone through what I’ve gone through, it was nice to get that moment,” Sizemore said.

His homer created a 1-1 tie in the fourth inning, but that would be the extent of the Boston offense. The Red Sox got nine hits and drew three walks, but they stranded 12 and went 0 for 10 with runners in scoring position.

PITTSBURGH — Barry Bonds drew a mixture of boos and cheers while presenting current Pittsburgh center fielder Andrew McCutchen with the 2013 NL MVP award. Bonds was the previous Pirates player to win the honor, earning the second of his record seven career MVP trophies in 1992.

“It feels good to be back where it all started,” Bonds said. “We had some great times here.”

Notes

• Catcher Yan Gomes and the Cleveland Indians completed a $23 million, six-year contract after his breakout season last year. Gomes’ deal includes club options for 2020 and 2021 that could bring the total to $42 million over eight years — or even $48 million with escalators.

• Toronto Blue Jays star Jose Reyes left the season opener at Tampa Bay after his first at-bat because of a tight left hamstring.

• Right-hander Joe Blanton rejoined the Oakland Athletics on a minor-league contract and will begin the season in the rotation of the Class AAA Sacramento River Cats.

• The Boston Red Sox put right fielder Shane Victorino on the 15-day disabled list because of a strained right hamstring. Jackie Bradley Jr. was recalled from Class AAA Pawtucket and Daniel Nava started in right field against the Orioles.

• Colorado Rockies right-hander Tyler Chatwood will be placed on the disabled list Tuesday and will miss his scheduled start Wednesday at Miami because of a strained left hamstring. Right-hander Jordan Lyles will be recalled from Class AAA Colorado Springs to take Chatwood’s turn.

• Major League Baseball’s average ticket price rose 2 percent this season to $27.93, the steepest rise since a 5 percent hike in 2009, according to the Team Marketing Report’s survey.
