DENVER -- One look at the win expectancy chart for Friday night’s Phillies-Rockies game at Coors Field, and you’d see something that might very well look like a chart depicting the emotional rollercoaster that the Phillies were on in a 4-3, 12-inning loss to Colorado.

When Raimel Tapia flied out to left field for the second out of the bottom of the 12th, Philadelphia’s win expectancy, per FanGraphs, was 88.2% thanks in large part to Bryce Harper, who -- as part of a career-high five-hit performance to break out of a 3-for-24 slump -- had given his club the lead with a go-ahead double minutes earlier.

That all changed with one swing of Charlie Blackmon’s bat, as the Rockies right fielder launched a two-out, two-strike, walk-off home run into the Phillies’ bullpen off reliever Juan Nicasio to take Philadelphia’s 88.2% win expectancy down to zero.

“Brutal,” manager Gabe Kapler said moments after the sudden, jarring defeat. “Just a brutal loss. No way to sugarcoat it. … This game was a crushing blow.”

The Phillies spent the better part of 11 innings unsuccessfully trying to support another strong outing from right-hander Vince Velasquez, whose ERA stands at 2.55 following 5 2/3 innings in which he gave up two runs on seven hits, walking one and striking out eight. The bullpen delivered six scoreless frames before the 1-2 pitch to Blackmon in the 12th.

It wasn’t for a lack of opportunity: Philadelphia was 1-for-16 with runners in scoring position, stranding 19 on base.

“We had 17 hits and only three runs,” Harper said. “That’s kind of crazy, especially at Coors Field. We can always be better, myself included. When we get guys on base, we’ve gotta get those guys in. It’s part of the game. The bullpen threw the crap out of it, and if we could’ve gotten a couple of those runs across, it might’ve been a different story tonight.”

For Harper’s part, there was no solace in his first five-hit game.

“I could’ve gone 0-for-7 and we could win a ballgame,” he said. “That’s all I care about.”

The loss was Philadelphia’s 12th in its last 16 games against Colorado. In that span, the Phillies have won one game at Coors Field. But more than that, it was a gut punch on a night when frustration reigned at the plate for most batters not named Harper, before that frustration transitioned in an instant to elation with Harper’s 12th-inning heroics, and moments later, visceral disappointment.

In the middle of all that came more bad news on the injury front: Both Scott Kingery and Andrew McCutchen had to exit early -- Kingery with a strained right hamstring and McCutchen with left knee inflammation. Jean Segura and Odubel Herrera are among the players already nursing injuries, both also dealing with hamstring strains.

“Our depth is definitely being tested right now,” Kapler said. “We’re going to have to find a way to step up for the guys that are banged up right now. It’s going to be a major point of emphasis for us.”

These are challenging times for the injury-riddled Phillies, who have dropped to 4-6 in their last 10 games, a span corresponding with their decline in production with men on base.

“It all started in Spring Training, when we were all bonding together -- it was kind of like a family, a brotherhood,” Velasquez said. “It sucks encountering these injuries, but I think that just makes this squad tighter and just adds to the fire of what we’re continuing to do.”

As for the Richter Scale of emotions, Velasquez summed up what many before him have, and many after him will experience in baseball.

“That’s what this game is going to do to you,” he said. “You don’t know what to expect until the game’s over. Tonight, unfortunately, it didn’t go our way.”
