A three-run home run by LF Jose Ruiz in the top of the sixth inning provided the winning run for the Acereros (Steelers).

The game was tied 1-1 going into the sixth. CF Eliezer Ortiz opened the scoring with a home run in the bottom of the third for the Rieleros (Railroaders), and 3B Olmo Rosario hit a long home run over the center field fence. Rieleros starter RHP Fredy Quintero was replaced by LHP Jose Sanchez after Quintero walked Rosario to start the sixth inning. Sanchez only faced two batters. He walked the first one, DH Brett Harper. (He was obviously having control problems.) The second batter he faced was Ruiz, and the result was the home run.

Ruiz' home run seemed to wake up the Rieleros offensively. DH Saul Soto led off the bottom of the sixth with a double. The next batter, 3B Danny Richar, drew a walk, and Soto and Richar moved to third and second on a wild pitch by Acereros starter RHP Jose Oyervidez. The next batter, C Carlos Rodriguez, hit a fly ball that was very close to being a three-run home run, but was a sacrifice fly instead. Richar moved to third. The next batter hit a popup that wasn't deep enough for Richar to come home, and he was stranded on third when a ground out ended the inning.

The Rieleros (Railroaders) of Aguascalientes entered this game one game out of the Mexican League playoffs. They played tonight like they want that playoff spot, but came up short in extra innings.

The starter for the Rieleros, Dominican Republican RHP Lorenzo Barcelo, has good credentials for playing in this league; he pitched 66 innings for the White Sox during 2000-02. He was upstaged by Acereros (Steelers) starter RHP Josh Lowey of Fort Walton Beach, FL, who played college ball at Mercer, then played several seasons of independent league ball before going to the Acereros last season. Lowey pitched six innings, allowed two runs on six hits, struck out nine. When he left the game, the Aceros had a 7-2 lead.

The lead didn't hold up. The first reliever for the Acereros, Juan Ramon Noriega, was charged with three runs on three hits, didn't record an out, and the Acereros lead was 7-5 after seven innings. (A sacrifice fly by 1B Jesus Castillo was just short of a three-run home run.) Rieleros relievers Emmanuel Torres and Jose Sanchez were able to keep the Acereos off the board in the top of the eighth. (The scoreboard in Estadio Alberto Romo Cavez doesn't show pitch speeds, but Torres was throwing some serious heat.) The Rieleros then took an 8-7 lead in the bottom of the eighth on a leadoff home run by 3B Danny Richar, followed by RBI singles by RF Carlos Ibarra and pinch-hittehr Omar Mendoza. Ibarra scored the go-ahead run, and it was the result of a defensive mistake. On his base hit, the Acereros threw home, even though the run had scored long before the throw. Ibarra was able to move to second on this throw, putting him in scoring position for Mendoza.

The USA won the first-ever women's baseball gold medal at the Pan American Games in Ajax, Ontario, defeating Canada 11-3 in the final. The game drew a capacity crowd of 5,224.

RHP Marti Sementelli, who played baseball and softball at Montreat, played a key role in this. She made two appearances, both in the preliminary round. She pitched the final inning of a 10-6 win over Venezuela, allowed no hits, walked one. She started the final preliminary round game against Canada, which the USA won 3-1. She pitched six shutout innings, scattered seven hits, struck out three, walked one, and got the win. She had to pitch her way out of a bases loaded and no outs situation in the fifth inning, and escaped with a pair of popups and a strikeout.

This game decided first place in the preliminary round, which meant that the USA got the next day off while Canada had to play Venezuela to get into the gold medal game. USA Coach Jonathan Pollard said, "Marti is probably our most experienced vet on this team with the exception of [Malaika] Underwood. No moment is too big for her which is why we had her going against Canada because we knew she could handle situations like that.”

Sementelli, of Sherman Oaks, CA, made 15 relief appearances for the Cavaliers in 2012, her freshman year. Her numbers were 0-1 (two saves), 5.94 ERA, seven strikeouts, and four bases on balls in 16 2/3 innings pitched. She switched to softball for the remainder of her time at Montreat.

Story from USA Baseball: WNT advances to gold-medal game with 3-1 win over Canada

Canada won its second straight gold medal in baseball in the 2015 Pan American Games, played in Ajax, Ontario.

In both 2011 and 2015, alumni of NAIA schools played a key role in Canada's win. The 2011 team had four players who played at NAIA schools, and RHP Chris Kissock of Lewis-Clark State played a key role for that team (story).

The 2015 edition included two NAIA alumni, LHP Jeff Francis of British Columbia and RHP Jared Mortensen of LSU-Shreveport. Francis got two saves during the preliminary round, retired all six batters he faced, struck out two of them. He was called upon to start the gold medal game against the USA. He went seven innings, allowed four runs (two of them on a home run by DH Patrick Kivlehan [Mariners organization, Rutgers]) on eight hits, struck out seven, and walked one. He got a no-decision; the game was tied 4-4 when he left it. Canada ultimately won the game 7-6 in ten innings; the tying and winning runs came on a bad pickoff attempt followed by a throwing error.
