Having run out of relievers and being unwilling to use anyone else from his starting rotation, Padres manager Bud Black turned to Josh Wilson(notes) — his team's second-string shortstop — to pitch Sunday afternoon.

"I expected it in that type of game," Wilson said. "It was probably just a matter of time. I was ready."

Wilson came within a strike of wriggling out of a jam in the 18th inning, but he allowed a go-ahead three-run home run to Arizona's Mark Reynolds(notes) in the Diamondbacks' 9-6 victory at PETCO Park in San Diego.

"One pitch away," Wilson said. "I had Mark 0-2 there. I wish I could have thrown a strike before I got to 3-2."

Hitting against a position player isn't as easy as one might think, Reynolds said.

"It's tough because, No. 1, he's a position player and you don't want him to get you out. No. 2, you don't know what he's going to throw," said Reynolds, who came into the at-bat 0-for-6 with four strikeouts.

Reynolds, who leads the league in strikeouts, also set the major-league record for whiffs in a season, 204, in '08.

Let's go the video, plus more details about the longest game in the majors this season.

• Wilson grooved an 88-mph "cutter" on a 3-2 pitch to Reynolds, who lined it (VIDEO) into the seats in right field for his 14th homer.

"I don't know how long I could have lasted. I started getting tired toward the end of that inning," said Wilson, who threw 29 pitches, including 16 for strikes.

• The game took 5 hours, 45 minutes and was the longest by time and innings since the Padres beat the Reds 12-9 on May 25, 2008. That game lasted 18 innings, 5 hours and 57 minutes.

• Capping a five-run ninth to tie the score at 6-all with two outs, David Eckstein(notes) hit his first career pinch-hit homer, a three-run shot against Chad Qualls(notes) (VIDEO). It also was his first homer of the season and third since the start of the 2008 season.

• Eckstein, a li'l fella at 5-foot-5 or so, has 33 homers in 4,866 career plate appearances. He is famous, however, for hitting grand slams in consecutive games against the Blue Jays back in 2002 (the second of which was a game-ender — whee!).

• After the Padres used up their relievers, starter Chad Gaudin(notes) — who took the loss in Friday's series opener — got in some "side" work by pitching the 16th and 17th.

• Four D-backs relievers no-hit the Padres for nine extra innings. Leo Rosales(notes) came in with a 6.94 ERA, but pitched the final 3 1/3 innings for the victory.

• Arizona manager A.J. Hinch figured the D-backs were good for 22 innings before needing to use a position player on the mound.

• The pitching staffs combined for 29 strikeouts and 16 walks.

• The Padres left only seven men on base (the D-backs stranded 16).

• Henry Blanco(notes), one of the Padres catchers, played third base in the 18th.

• Padres infielder Chris Burke(notes) made the game's only error.

• Both starting catchers — San Diego's Nick Hundley(notes) and Arizona's Miguel Montero(notes) — played the whole game behind the plate.

• The Padres have played the two longest games in the majors this season; they took 5 hours, 14 minutes to beat Cincinnati 6-5 in 16 innings on May 16.

• Arizona's Justin Upton(notes) left the game in the 10th after aggravating an injury to his left shoulder.

• Edgar Gonzalez had the only multi-hit game for the Padres, going 2-for-7. Brian Giles(notes) (0-for-6) was the only starter (other than the pitcher) to go hitless, but Chase Headley(notes) (1-for-8) stuck out five times.

• Wilson entered the game at shortstop in the top of the 12th.

• He was claimed off waivers from the D-backs on May 14. Three days earlier, the D-backs used the 28-year-old right-hander in relief. He pitched a hitless inning of mop-up duty in a 13-5 loss against the Reds.

• Wilson's first relief career appearance — a scoreless inning — came in 2007 for the Devil Rays.

• Wilson's line: 1 IP, 3 H, 3 ER, BB, HR. ERA: 13.50. WHIP: 2.50. He also went 0-for-3 with a strikeout, dropping his batting average to .164.
