Iowa's Arismendy Alcantara fielded the final out, a routine chopper to second, with all the concentration he had remaining after 13 innings.

He didn't want to spoil the game of his life.

"I said, 'Finally,'" Alcantara said. "I made sure of the catch first, then made the throw."

The play capped a 9-6 victory for the Cubs over the Sky Sox on Saturday in a marathon that saw Alcantara drive in the tying run with an infield single with two outs and two strikes in the ninth, then add a key insurance run with an RBI triple in the 13th.

The second baseman and a key part of the Chicago Cubs' future went 5 for 7 with three RBIs, and he scored the game's final run.

"Five hits in a game for the first time," said the native of the Dominican Republic, who is ranked by Baseball America as the No. 7 prospect in Chicago's system. "It feels pretty good."

The Cubs jumped to a 2-0 lead after three innings before the Sky Sox sprang to life for the first time in this series after being outscored 18-2 in the first two games. The teams exchanged leads in the fourth, five, sixth before, in the seventh, Colorado Springs went ahead on back-to-back home runs from Ben Paulsen and Michael McKenry, two of the five total home runs on a day in which the wind was howling out to left from the right field foul pole.

Manny Corpas worked 11/3 perfect innings in relief and Greg Burke followed with an eighth inning in which he struck out all three batters he faced - Iowa's No. 4, 5 and 6 hitters.

But Burke couldn't close it in the ninth when Logan Watkins led off with a single, Lars Anderson was hit by a pitch and Alcantara's shot to short wasn't handled by Paul Janish.

The offenses, which combined for 32 hits - 16 apiece - then went dormant for the first three extra innings.

The Cubs took the lead when Jonathan Mota singled a 3-1 Rob Scahill pitch up the middle to drive in Watkins with the go-ahead run.

Alcantara then provided insurance with his triple.

"It was a long day," Alcantara said. "When I hit it, I knew it would bring in a run. It was a long day, we had to go.

"It was a crazy day."

Crazy indeed, as the Sky Sox lost despite 15 strikeouts from their pitching staff, five extra base hits and a 4-for-6 performance from McKenry.

Christian Friedrich started for Colorado Springs, as the former No. 1 pick went 52/3 innings, giving up five earned runs and eight hits while striking out five and walking two. He gave up three solo home runs.

The game took 4 hours, 11 minutes to complete.
