The following are the 10 games the Pirates have won in 2013 in which they had they lowest win expectancy percentage from fangraphs.
10. April 27, Pirates 5 Cardinals 3. Lowest WE: 15.4% (Trailing 2-0 in the 6th inning)
From the game recap "That gave the Cards a 2-0 lead heading into the seventh. They inserted Joe Kelly, and things quickly went haywire for them. First, Pedro Alvarez singled. Then, quickly and unexpectedly, Russell Martin hit an opposite-field, two-run homer to tie the game. It almost felt unreal, as if the Pirates had done little to deserve to be tied, but that's the power of the home run. In any case, though, Kelly didn't stop there. Clint Barmes singled, still with no outs. James McDonald, who pinch-hit because the Pirates had a short bench, couldn't lay down a bunt, but then Starling Marte walked. Trevor Rosenthal relieved Kelly after that and struggled to throw strikes, hitting Jose Tabata and then walking Andrew McCutchen to bring in the go-ahead run. Garrett Jones then recorded an RBI groundout to make it 4-2."
9. April 24, Pirates 5 Phillies 3. Lowest WE: 13.8% (Trailing 3-1 in the 7th)
From the game recap "Then, in the seventh, Alvarez homered off lefty Antonio Bastardo to make it 3-2. Then, in the eighth, the Bucs took a 4-3 lead after RBI singles by Travis Snider and Brandon Inge. Starling Marte tripled in a run in the ninth to give the Pirates insurance, and Jason Grilli pitched the ninth to get the save."
8. April 25, Pirates 6 Phillies 4. Lowest WE: 13.6% (Also Trailing 3-1 in the 7th)
From the game recap: "Then in the eighth, the Phillies brought in righty Phillippe Aumont, and HANG ON, TRAVIS SNIDER AND GARRETT JONES JUST LEAPT INTO THE RING CARRYING FOLDING CHAIRS. It was Jones whose blow was the most devastating, with a two-run double that put the Pirates up by two."
7. May 29, Pirates 5 Tigers 3. Lowest WE: 13.3% (Again Trailing 3-1 in the 7th)
From the game recap: "Sanchez had been striking out the Pirates all day, much like Rick Porcello did last night. But the Bucs, down 3-1, finally got to him in the seventh. Garrett Jones hit a one-out single, and Russell Martin walked. Then Pedro Alvarez doubled to center to bring home two runs, and Travis Snider brought home Alvarez with a double of his own. Then Snider moved up on a wild pitch, and Jordy Mercer brought him home with a perfect suicide squeeze."
6. May 21, Pirates 5 Cubs 4. Lowest WE: 10.8% (Trailing 3-0 in the 5th)
From the game recap: "Garza pitched five shutout innings, but it was his season debut, so the Cubs pulled him after 82 pitches. That worked out brilliantly for the Pirates. Hector Rondon entered and promptly loaded the bases, leaving with one out. James Russell then walked Pedro Alvarez to bring in a run. Then, after Gaby Sanchez flied out, Travis Snider pinch-hit for Clint Barmes, and homered just over the fence in right-center."
5. May 17, Pirates 5 Astros 4. Lowest WE: 10.6% (Trailing 4-1 in the 6th)
From the game recap: "So, on to the ninth! The Astros are using a pitcher named Edgar Gonzalez, whose last 12 months ... I'm not going to look it up, but I think it's involved playing in, let's say, Oklahoma City, Buffalo, Quad Cities, Bozeman, Tijuana, Mozambique and Pyongyang. He's allowed 11 runs in 12.2 innings in the majors this season. There is no reason whatsoever to think he's any good at all. The Astros have him pitching the ninth in a tie game. Starling Marte leads off with an excuse-me single to right. Travis Snider grounds into a force out. And then Andrew McCutchen singles to right. Whee! First and third, one out. Brandon Inge then hits a double play ball that should send the game to extra innings, but Gonzalez can't make the play. Snider doesn't advance, but everyone's safe on Gonzalez's error. Neil Walker then gets called out on strikes in a terrible at bat. And then ... Russell Martin reaches as Jimmy Paredes comes flying in from right field on a fly ball and runs into Elmore, who's camped under it."
4. May 1, Pirates 6 Brewers 4. Lowest WE: 8.7% (Trailing 4-2 in the 7th)
From the game recap: "In the eighth, Travis Snider led off with a pinch-hit single, and Starling Marte golfed a low fastball over the fence in center to tie the game. Then Jose Tabata singled and stole second, apparently injuring his leg in the process. James McDonald pinch-ran and came home on Brandon Inge's single. Inge advanced all the way to third on an error, then came home himself on a single by Alvarez. Mark Melancon and Jason Grilli did their usual thing, and that was it. Hey, what do you know? It's possible to win in Milwaukee."
3. June 2, Pirates 5 Reds 4, 11 innings. Lowest WE: 7.1 (Trailing 4-2 in the 8th)
From the game recap: "Then, in the bottom of the eighth, Garrett Jones tied the game with a ridiculous two-run blast that hit the water on the fly. The Pirates had Jason Grilli warming even before that, and he had a very Grilli-like ninth, striking out the side. Then Justin Wilson came on to pitch the 10th and 11th before the Pirates put two men on in the 11th for Snider, who hit the game-winning single to right field."
2. June 23, Pirates 10 Angels 9, 10 innings. Lowest WE: 2.4% (Trailing 6-3 in the 9th)
From the game recap: "So it stood 6-3 in the 9th, with the Pirates on the verge of missing a golden opportunity to further establish their bona fides as one of the best teams in MLB. Except they didn't. An Andrew McCutchen pinch-hit forceout with runners on first and third brought in one run, but left two outs. Russell Martin, though, followed with a double and Starling Marte singled to tie the game. Then in the 10th, an Alvarez double and two walks loaded the bases for Travis Snider with one out. Snider looped a single to left, with three runs scoring after the ball got away from J.B. Schuck. Following a McCutchen single, Martin singled in another run to make it 10-6. Incredibly, that almost wasn't enough. Jason Grilli had his first true meltdown of the year, giving up five hits and three runs. The Angels got the tying and winning runs to scoring position for none other than Mike Trout, but Grilli gathered himself to strike Trout out on a slider."
1. April 14, Pirates 10 Reds 7. Lowest WE: 1.8% (Trailing 5-0 in the 7th)
From the game recap: "The score remained at 5-0 until the seventh. But then the Pirates finally came to life. Michael McKenry homered to center leading off the inning, and it looked like that would be all the Bucs would get, as John McDonald and Jose Tabata made outs. But the Pirates put together a string of two-out hits. Starling Marte singled, and then Travis Snider belted a fly ball that nearly cleared the Clemente Wall but ended up a double. Then Andrew McCutchen doubled and Gaby Sanchez singled, and the score was 5-4. The Reds scored one in the top of the eighth, but the Pirates' offense wasn't through, blowing the game open with six runs in the bottom of the inning. McKenry hit another home run, a two-run shot. (Will we soon be calling for McKenry to start over Russell Martin, the way we did last year with McKenry and Rod Barajas? Probably not, but it's great that McKenry still has the ability to make us wonder.) Then Tabata walked, and Marte homered to bring him in. Then Jonathan Sanchez pinch-hit (!) and walked (!!), and McCutchen followed with a single, and Gaby Sanchez hit a sacrifice fly to bring home Jonathan Sanchez. (It's too bad Tony Sanchez wasn't around to pinch-run for McCutchen there. You've got to get them all involved.) Then Neil Walker chipped in, bringing home McCutchen with a single."
